Everyone knows that the timing belt is a very important component in the engine of every car. The factor of economical fuel consumption directly depends on its optimal functioning; it also affects the overall behavior of the car. The Hyundai ix35 uses a timing chain as a timing drive. With its help, synchronized rotation of the crankshafts and camshafts is carried out.

Regulations for replacing a chain in theory and practice

The chain, of course, is much more reliable than a belt drive. It cannot break; its service life is slightly longer than that of a belt. But all this does not mean that it will serve forever and there is no need to monitor it. The service life of the chain drive is regulated and is approximately 150,000 km. In some cases, it fails a little earlier. This may be due to using the car in poor driving conditions, constant extreme driving and some other factors. If the engine experiences maximum load for a long time, this may even cause a circuit break. Yes, sometimes, although very rarely, this happens. But the chain coming off the sprockets is a very common occurrence. So, in order to prevent the chain transmission from breaking or coming off, its condition must be constantly monitored.

Some car enthusiasts claim that in modern cars the chain drive is tensioned automatically, so there is no need to look under the hood because of it. Of course, automatic tensioning is very good, but at least for the sake of common sense, sometimes it is still worth taking an interest in the condition of the chain. Increased loads can cause the chain to sag, which can lead to it coming off the sprockets. A slack chain will constantly make noise, which is also not very good.

But what happens if the chain does break? In this case, the pistons will hit the valves with great force. Both will suffer from this. This will inevitably cause the pistons to bend, and the bushings and valve seats will be destroyed. None of this will happen if you check the condition of the chain drive in time and promptly detect its sagging. If the chain does not sag much, then you can try to tighten it manually. Severe sagging cannot be eliminated, and this requires replacing the sagging chain with a new one.

Replacement procedure

Here we come to the main topic of this article. Here we will talk about how you can independently carry out the procedure for replacing the timing chain. Let’s start with what we actually need for this. Of course, you will have to go to the store and buy a new consumable there. We are talking here not only about the chain itself; most likely, the tensioner and dampers will also have to be replaced. Like all consumables, they also need periodic replacement. You will also have to prepare a set of keys, sockets, screwdrivers with different blades, a jack and a wrench. If you already have all this at hand, then you can start.

We change the timing chain drive on our own

Remember that work can only be done when the engine is cool. The left terminal must be disconnected from the battery, which will lead to the car being de-energized.

Remove the casing from the cylinder block. To do this you will have to unscrew 16 bolts.

Remove the ignition coil.

Disconnect the ventilation system hose.

There is a gasket in the cylinder block cover connector. Don't forget to remove it.

There is also a gasket in the spark plug well block. It also needs to be removed from there.

All mounting surfaces must be thoroughly cleaned of dirt, traces of oil and used sealant.

All these were only preparatory procedures, after which you can begin to directly remove the timing chain.

1. Set the piston of the first cylinder to the dead center position.
2. Prepare the container and pour the engine oil into it.
3. Now we begin to remove the power unit. Let's start with its top bracket.
4. Remove the drive of the auxiliary structures.
5. Dismantle the power steering pump. Here we will have to unscrew a few bolts. We move the hydraulic booster to the side.

6. Remove the tensioner, for which you will have to first unscrew the bolt securing it.
7. Now remove the lower bracket of the right support. It is secured with four bolts.
8. The accessory drive has a tension roller. It is this that needs to be removed at the next stage.
9. Remove the water pump.
10. Remove the generator pulley. In this case, the pulley will have to be constantly held from turning. After this, we remove the generator itself.

11. Remove the generator bracket, having previously unscrewed the 2 bolts securing it.
12. But to remove the timing cover, you will have to unscrew as many as 14 bolts. Unscrew them and remove the cover.
13. Press the tensioner using a screwdriver and fix it.
14. Turn the camshaft to the right and remove the chain and gear.
15. Now you can install the new chain. At the same time, make sure that the marks on the chain itself (painted links) and on the camshaft sprockets match. The pin on the crankshaft must be at the top during installation.
16. Clean the seats from dirt and used sealant.
17. Install the tensioner and once again check that the marks are positioned correctly.
18. We put all other parts in the reverse order.

Be sure to replace the crankshaft seals every time you replace the chain. Otherwise, it may happen that you have to disassemble the entire mechanism just because of them.

FUNCTIONAL PURPOSE OF THE TIMING CHAIN

The Hyundai ix35 timing chain drive is part of the gas distribution mechanism and is involved in the transmission of torque from the crankshaft to the camshaft. The chain can connect them directly or participate in the work indirectly, for example, combining camshafts with each other, if there are two of them, while its functional purpose remains unchanged.

Monitoring the condition of the timing chain, replacing dampers and tensioners is part of routine vehicle maintenance and plays an important role in the operation of the vehicle engine. It is necessary to regularly monitor the condition of the gas distribution system, as this directly affects the vehicle’s power, sensitivity when supplying gas and fuel consumption.

FEATURES OF CHAIN ​​REPLACEMENT

In most engines of older car models, chains with roller links were used to transmit torque, often the components were in two or three rows, this made the timing chain a very reliable, almost eternal mechanism that does not require constant maintenance. Often the car traveled up to 300,000 km. and the chain of the mechanism received only lateral play, and the worst thing that could happen to the gas distribution mechanism was the links jumping; breaks were extremely rare. Over time, production price, efficiency, environmental friendliness and the weight of the car engine, which affects its power, have become trends in the creation of cars. Under these conditions, manufacturers began to strive to replace the timing chain with a lighter, cheaper and easier to maintain timing belt. And those motors whose design retained chains and roller components were replaced with lightweight plate links, more reliable than timing belts, but still not as strong as roller chains.

The Hyundai ix35 timing chain has a number of features that fundamentally distinguish it from the timing belt.

1. The chain is a durable mechanism; it wears out much longer than the timing belt; breaks do occur, but much less frequently than in belt-driven engines.

2. A break in the timing chain occurs quite rarely, which means engine breakdowns requiring expensive overhauls do not occur often.

3. Timing chains are quite noisy, but with the modern level of car noise insulation, this parameter becomes not very important.

4. When the chain wears out, its play and lateral runout occur, this indicates the need to replace the old chain with a new one. Since the metal part sagging and lateral runout is accompanied by strong noise, it is simply impossible not to notice and not to attach significance to it. A noise under the hood will be the first “bell” indicating the need for vehicle maintenance.

5. The main disadvantage of replacing the Hyundai ix35 timing chain is that it is located inside the cylinder block and it is quite difficult to assess its condition without training and experience. In addition, dismantling and replacement, with such a device, is a long and labor-intensive process, and therefore expensive.

6. Tensioners and dampers are involved in the operation of the timing chain - these are consumable parts that wear out quickly and require more frequent replacements than the timing chain itself.

TYPES OF FAULTS

1. Timing chains, when in full working order, have a natural movement, which is compensated by tensioners when oil pressure is applied. A malfunction is considered to be a strong lateral runout of the timing chain, which appears when the links are stretched. The actual degree of chain stretch can only be determined through a qualified inspection of the gas distribution mechanism.

2. Backlash is a direct stretching of the chain, which is observed during long-term operation, can lead to jumping of chain links and malfunction of the gas distribution mechanism, this leads to a decrease in the sensitivity of the engine when the gas pedal is pressed and an increase in fuel consumption.

3. Broken timing chain of Hyundai ix35 is the most dangerous damage to the engine; in the case of a chain drive motor, it does not occur often, but it does occur. If such a malfunction occurs, the camshaft ceases to be connected to the crankshaft and can stop completely arbitrarily in a position in which any of the valves of the gas distribution mechanism is open. In this case, the piston, moving upward, may collide with the valve, which will lead to its deformation and the car engine will face serious repairs. It should be noted that a timing chain break does not occur unexpectedly; it is almost always accompanied by changes in the operation of the vehicle, a decrease in its power, a change in gasoline consumption and the appearance of extraneous noise.

To prevent and prevent the operation of the gas distribution mechanism, it is necessary to periodically troubleshoot the timing chain; this will save the car engine from breakdown, prevent premature engine wear and increase its service life.

CAUSES OF WEAR

1. Operating a Hyundai ix35 in extreme conditions. Frequent driving on unpaved roads, towing trailers, heavy loads, and traveling at high speeds increases the load on the crankshaft, spinning it to maximum speed, which leads to stretching of the timing chain.

2. Since the timing chain is located inside the cylinder block, it is completely washed by engine oil and, as a result, is very sensitive to its quality. In the case of using high-quality synthetic oil containing specialized detergent additives, the service life of the timing chain is significantly increased

3. The operation of the timing chain involves parts that regulate the tension of the chain; they are consumables and require periodic replacement. During vehicle maintenance, it is necessary to check the degree of wear of the tensioner and the “calculator”; untimely replacement of these parts can lead to stretching of the chain and skipping of links.

SIGNS OF PROBLEM

1. Increase in gasoline consumption by car;

2. Reduced engine power; 3. The appearance of clanging and noise under the hood of the car when the engine is running;

4. A complete stop of the car while moving; when you try to start, the engine does not start, and the starter rotates more easily than usual;

5. Unstable operation of the Hyundai ix35 engine at idle and while driving;

6. The occurrence of shots in the injector receiver and exhaust pipe.

All these problems may indicate a shift in the valve timing and loosening of the chain tension. If you notice one or more signs of this list on your car, immediately contact a service station for an inspection.

HOW OFTEN DO YOU NEED TO REPLACE THE TIMING CHAIN?

The frequency of replacing any consumables for Hyundai ix35 cars depends on the driving style and operating mode of the car. With an extreme driving style and aggressive use of the vehicle, it is necessary to replace the timing chain as it becomes loose and wears out.

Under normal operating conditions, it is necessary to replace the timing chain as planned, every 100 - 150,000 km. mileage If your car has an analog belt, replacement must be done a little earlier than the time recommended by the vehicle manufacturer.

Trust your car only to professional specialists who are capable of competently troubleshooting the timing chain, assessing lateral runout and backlash, replacing and adjusting the operation of tensioners, chain drive "pretensioners" and replacing the Hyundai ix35 timing chain.

The Hyundai ix35 replaced the popular Tucson in 2010. The crossover is built on the same platform as the third generation Kia Sportage. The ix35 was assembled in South Korea, as well as in Europe - at the Kia factories in Slovakia and Hyundai in the Czech Republic.

Engines

On the Russian market, the Hyundai ix 35 was offered with 2-liter engines: gasoline (150 hp) and diesel (136 and 184 hp). All power units have a timing chain drive.

Some owners of gasoline IX 35 after 50-150 thousand km notice an extraneous knocking sound while the engine is running. The reasons were different: a faulty hydraulic chain tensioner, a CVVT clutch (variable valve timing), hydraulic compensators (installed after restyling in 2013) or even scuffs in the cylinders.

Fortunately, bullies are not an endemic phenomenon. When applying during the warranty period, dealers did not replace the entire engine, but only the “short block” complete with pistons and crankshaft. If the warranty is out, then the block will have to be sleeved - from 100,000 rubles.

Starting the engine may be difficult due to a malfunction of the clutch pedal switch (with a manual transmission) / brake pedal (with an automatic transmission), and in cold weather - due to a “retracting” starter (the lubricant thickens).

In diesel units, after 50-100 thousand km, sometimes the crankshaft damper pulley is rented out (from 7,000 rubles). And problems with starting a cold diesel engine arise due to poor contact or oxidation at the crimping point of the glow plug strip wiring (about 1,000 rubles). In addition, the glow plug relay (from 4,000 rubles) or the spark plugs themselves (1,500 rubles/piece) may fail.

Front box

For the ix 35 there are three gearboxes: 5 and 6-speed manual, as well as a 6-speed automatic. There are no serious problems with the boxes. In the case of manual transmissions, many note the appearance of extraneous noise that disappears after depressing the clutch, and in the case of automatic transmissions, owners complain about noticeable shocks during shifts.

Transmission

Poor protection of spline connections of drive elements from exposure to water and dirt leads to unpleasant consequences. So, after 50-100 thousand km, corrosion kills the spline joint of the right composite drive shaft. The splines are licked - there is a backlash and a hum. The intermediate shaft and inner CV joint have to be replaced: 7,000 rubles per element plus 3,000 rubles for labor.

Worse, the mounting of the intermediate shaft support bearing may break off. The mount is part of the block. Ideally, the block needs to be replaced, but argon welding can get rid of it. Fortunately, this problem is much less common.

Another example of poor protection of spline joints is corrosion and cutting of the drive shaft splines in the transfer case and differential cup (after 100-150 thousand km). The repair will be very expensive - about 80,000 rubles. Owners of diesel cars are primarily at risk. Prevention of spline joints will help to avoid problems - lubrication every 30-40 thousand km. In addition, the high torque of diesel engines can lead to the destruction of the differential basket along the weld seam.

The Hyundai ix 35 used two all-wheel drive couplings. Until 2011, an electromagnetic clutch of Japanese origin JTEKT was installed, and since 2011, a hydraulic clutch from the Austrian manufacturer Magna Steyr was installed. The coupling is quite reliable. Malfunctions occur due to damage to the wiring (3,000 rubles) or wear of the electric motor brushes (at high mileage). After 100,000 km, the clutch seal sometimes begins to leak.

The outboard bearing of the propeller shaft (4-5 thousand rubles) can hum after 80-140 thousand km.

Chassis

Knocking suspension is the reason for many complaints about Hyundai, and not only the ix35. Knocks when driving over uneven surfaces worsen with the arrival of cold weather. There are several sources of extraneous sounds. The main thing is the original shock absorber struts, which can begin to knock after 2-3 thousand km. Official services replaced the racks under warranty. But that didn't mean they wouldn't knock again. After all, the new shock absorbers are the same. Some managed to change them three times in 20,000 km. But the problem is not total; there are also those who have driven up to 80-100 thousand km without ever noticing that there is something knocking in the suspension.

Another source of knocking is the boot and bumper of the shock absorber strut flying off the seat. The manufacturer recommended fixing the boot on the stand using sealant. The popular method is to wrap electrical tape around the rod or tie the “buffer” (bump stop) with clamps. On the ix35 2012 model year, the manufacturer eliminated this design flaw.

After 50,000 km, the steering rack may knock. Wheel bearings (from 1,000 rubles) last more than 60-100 thousand km.

Silent blocks and ball bearings of levers serve more than 100-150 thousand km. But the rear arm bracket, to which the stabilizer bar is attached, can collapse after 60-100 thousand km. The bracket can be welded. The new lever is available for 9,000 rubles. The defect affects exclusively all-wheel drive versions of the Hyundai IX 35.

Body and interior

The paintwork is traditionally soft, scratches easily, and becomes chipped over time. Unfortunately, after 3-6 years, paint blistering can sometimes be found on the rear wheel arches, tailgate, hood, roof and windshield pillars. Dealers are reluctant to recognize this problem as a warranty issue.

The interior of the IX 35 often begins to creak, especially in winter - before the interior warms up. Most often, the source of extraneous sounds is the armrest between the front seats.

Another unpleasant moment is the crumbling filling of the driver's seat cushion. Due to close friction with the sharp edges of the frame, the “inside” can crumble completely in just 30,000 km. What is surprising is the persistence with which the manufacturer changed the seat cushion over and over again until the warranty expired. Only in 2015 was it decided to install a special lining on the frame that resists destructive friction.

It’s the same story with the peeling leather covering of the steering wheel and door trim, at the point of contact with the driver’s elbow. The “leather” of the chairs is also not durable. Wrinkles appear on the driver's seat, the leather cracks and tears.

Sometimes the heater motor starts making noise (it needs to be disassembled, cleaned and lubricated), or the plastic air duct casing under the passenger seat flies out of its place. There are also failures of parking sensors, rear view cameras and “glitches” of the standard radio. There have also been cases of spontaneous ignition of control lamps followed by a short-term extinguishing of the instrument panel. In such cases, dealers changed the “tidy”.

Conclusion

When choosing a used Hyundai ix35, special attention should be paid to the operation of the all-wheel drive system. Other defects can be easily eliminated.

FUNCTIONAL PURPOSE OF THE TIMING BELT

Replacing the timing belt is part of routine maintenance on your Hyundai ix35 and plays an important role in the performance of the vehicle's engine. Untimely replacement of the belt can lead to a malfunction of the engine, and a break can lead to deformation of the gas distribution valve and the need for a major engine overhaul.

All parts of the gas distribution mechanism are closely connected to each other; the injection of the air-fuel mixture drives the piston of the engine cylinder, which in turn pushes the crankshaft, connected by a drive belt to the camshaft. Thus, the camshaft moves, which regulates the frequency of valve movement. The Hyundai ix35 timing belt connects the gears together and transmits torque from the crankshaft to the camshaft, affecting its rotation speed. If the system is working properly, their speed should be equal.

TYPES OF TIMING BELT FAULTS

Wear of the timing belt leads to a change in the torque transmission force from the crankshaft to the camshaft, resulting in a change in the frequency of movement of the engine pistons and valves. This, in turn, leads to a malfunction of the gas distribution system, rapid heating of the engine and, as a consequence, a decrease in engine power and an increase in consumption of the fuel mixture. For reliable and uninterrupted operation of the engine, it is necessary that the valves close and open at the same frequency as the engine pistons. If the timing belt slips due to wear, it can cause a break.

A broken Hyundai ix35 timing belt is the most dangerous damage to the engine. If such a malfunction occurs, the camshaft ceases to be connected to the crankshaft and can stop completely arbitrarily in a position in which any of the valves of the gas distribution mechanism is open. In this case, the piston, moving upward, may collide with the valve, which will lead to its deformation. In this case, the car engine faces serious repairs. It should be noted that a timing belt break does not occur unexpectedly; it is almost always accompanied by changes in the operation of the car engine, a decrease in its power, a change in gasoline consumption, the appearance of extraneous squeaks, creaks, etc.

To prevent and prevent the operation of the gas distribution mechanism, it is necessary to periodically replace the timing belt; this will save the engine of the Hyundai ix35 from breakdown, prevent premature engine wear and increase its service life.

CAUSES AND ASSESSMENT OF TIMING BELT WEAR

Timing belt wear occurs for a number of reasons, avoiding which can extend the life of the car engine.

To prevent complete wear of the timing belt, it is necessary to periodically, during a visual inspection of the gas distribution mechanism, check for damage to the surface of the belt. To inspect and evaluate the belt drive, it is necessary to unscrew and remove the protective casing of the mechanism under which the engine is hidden. The first signs of wear are:

• the appearance of oil and antifreeze smudges capable of chemically destroying the timing belt, with prolonged exposure;
• the occurrence of longitudinal cracks on the rear surface of the belt;
• formation of transverse cracks on the inner surface of the drive belt;
• a torn surface and a broken edge are also signs of wear;
• Rubber dust on the surface of the part also indicates belt wear;
• If the timing belt teeth begin to peel off or wear off, the part must be immediately replaced with a new one.

SIGNS OF A FAULTY TIMING BELT

Gasoline consumption by car has increased

Engine power has decreased

A complete stop of the car while moving; when you try to start, the engine does not start, and the starter rotates more easily than usual

Unstable engine operation at idle and while driving;

The occurrence of shots in the injector receiver and exhaust pipe

All these problems may indicate a shift in the valve timing and loosening of the belt tension. If you notice one or more signs from this list on your Hyundai ix35 car, immediately contact a service station for an inspection.

HOW OFTEN IS IT NEEDED TO REPLACE THE Hyundai ix35 TIMING BELT

The frequency of replacing any consumables for cars depends on the driving style and operating mode of the car. In case of extreme driving style and aggressive use of the vehicle, it is necessary to replace the timing belt as it wears out and the teeth wear out.

Under normal operating conditions, it is necessary to replace the original timing belt as planned, every 60 - 70,000 km. mileage During this period, it exhausts its resource and becomes unusable. If your Hyundai ix35 is equipped with an analog belt, replacement must be made a little earlier than the time recommended by the vehicle manufacturer.

WHICH TIMING BELT IS BETTER TO CHOOSE

Modern belts for the gas distribution system are a high-tech product, characterized by increased strength and wear resistance, capable of withstanding high dynamic loads. Timing belts are made from neoprene or polychloroprene with reinforcement with strong cord threads made of fiberglass, nylon and cotton.

To avoid the mistake associated with purchasing a timing belt, contact specialists who will help you, using your car’s WIN code, order a timing belt suitable for your car’s engine. This part is one of the most important in the design of the engine; the slightest deviation in the length, width, shape and size of the teeth can lead to problems with the engine of the Hyundai ix35.

Do not try to save money when buying a timing belt; a cheap product may be a low-quality fake that will quickly become unusable and in the future may cause serious engine damage. The best option for any car is original parts; their cost is higher than analogue ones, but when using the car they quickly pay for themselves.

When purchasing a timing belt, check its rigidity; a good belt should be elastic and bend easily. The worse the belt, the stiffer it will be.

The presence of teeth, sagging, or pores on the belt is not allowed - these are signs of a low-quality belt that will quickly become unusable. The surface of the product must be smooth, small burrs are allowed.

When purchasing it yourself, check the timing belt part number printed on the back side; it must correspond to the WIN code of the car. If it is not possible to compare the code of the belt and the car, then it is necessary to make a visual comparison of the old and new belt; they must be completely identical.

To avoid buying counterfeits, try to purchase spare parts only from official, trusted dealers.

Don’t skimp on a qualified timing belt replacement; contact our certified auto service center, where competent mechanics will help you repair your Hyundai ix35. And in the spare parts store you can buy original spare parts for your car.

  INTRODUCTION

  Hyundai Tucson is named after the North American city in Arizona. In the language of the native inhabitants of these places, the Pima Indians, the word Tucson means “spring at the foot of the black mountain.” The name of this “city of the sun” (more than 300 sunny days a year) perfectly suits one of the most popular Hyundai models - more than 1 million cars sold.

  The next generation of Hyundai Tucson was presented to the public at the automobile exhibition in Frankfurt on September 3, 2009. At the same time, sales began in South Korea under the name Tucson ix. Since in fact the new car turned out to be a class higher than its predecessor, already in January 2010 it was announced that the Tucson model would be discontinued, and the car continued to be produced absolutely unchanged under the name Tucson ix35 in Europe at the Kia Motors Slovakia plant.

  

  The Korean manufacturer spent three years and $225 million creating the new crossover. The car was designed in Europe, at the Hyundai Technology and Design Center in Rüsselsheim, by an international team consisting of specialists from the USA, Europe and Korea. It was possible to significantly reduce costs by using the platform of the previous generation Hyundai Tucson, which has undergone minor modernization. The new car has noticeably increased in size, thanks to which even 5 adults in the cabin will feel constant comfort during the trip. The dimensions of the luggage compartment have also increased - it has become deeper by 67 mm and wider by 110 mm. Innovations in the overall design of the car also affected the height of the trunk - it became smaller by 80 mm. However, unlike the previous Tucson, it is impossible to open the rear window separately.

  

  The exterior design of the new crossover, according to the designers, is based on the concept of “flowing lines.” The sporty appearance is emphasized by the graphic elements of the new hexagonal radiator grille, the aggressive contours of the lower air intake, the sculpted curves of the hood, the headlights extending onto the fenders, the shape of the roof and body lines. Hyundai ix35 turned out to be sporty, dynamic, powerful, but at the same time refined and light.

  

  In addition to the exterior, the interior is functional and elegant. The build quality, interior materials and ergonomics are at the highest level. All controls are very convenient and easy to use. The center console houses a large touchscreen display of the multimedia system. The four-spoke steering wheel with remote control buttons for the audio system is adjustable not only for tilt, but also for horizontal reach. Rear seat passengers do not feel a lack of free space. Both the front and rear seats of the car are equipped with a heating function, while in the front seats heating elements are built not only into the cushions, but also into the seat backs.
  The line of power units installed on the Hyundai ix35 is represented by two in-line four-cylinder gasoline engines with displacements of 2.0 liters and 2.4 liters and a power output of 150 hp, respectively. With. and 176 l. s., as well as one two-liter diesel engine with a capacity of 136 and 184 hp. With. depending on the degree of forcing. All engines can be paired with either a five- or six-speed manual or a six-speed automatic transmission. Traditionally, for this class of cars, two types of drive are offered: front-wheel drive and all-wheel drive.
  The basic package boasts six airbags, including side curtains, active front head restraints, a light sensor for automatic headlight activation, a high-quality MP3 radio with USB and AUX connectors, as well as 17-inch alloy wheels. More expensive modifications, in addition to all of the above, are also equipped with Electronic Stability Program (ESP) - a vehicle dynamic stabilization system that maintains directional stability, with an assistance system when starting uphill and when descending from a mountain, an engine start button, parking sensors and a camera rear view, dual-zone climate control and 18-inch alloy wheels. The richest configuration has a panoramic roof with a sliding sunroof, a tire pressure monitoring system and an interior trimmed with leather in two colors.
  Hyundai Tucson/ix35 is a car designed to become a symbol of success, freedom, youth and sporting spirit.
  This manual provides instructions for the operation and repair of all modifications of the Hyundai Tucson/ix35 produced since 2009.

22. Remove the chain tensioner (A) and chain tensioner arm (B).

23. Remove the timing chain.

24. Remove the chain guide (A).

25. Remove the timing chain oil nozzle (A).

26. Remove the drive chain sprocket from the crankshaft (B).

27. Remove the balance shaft (oil pump) chain.

INSTALLATION

1. Install the balance shaft (oil pump) drive chain.

2. Install the sprocket (B) of the crankshaft drive chain.

3. Install the chain oil nozzle (A).

Note:
Tightening torque: 7.8-9.8 N m.

4. Install the crankshaft so that the key is flush with the mating surface of the main bearing cap. Position the intake and exhaust camshafts so that the top dead center (TDC) marks on the sprockets are flush with the top surface of the cylinder head. As a result, the piston position of cylinder No. 1 will be at top dead center (TDC), compression stroke.

5. Install the timing chain guide (A).

Note:
Tightening torque: 9.8-11.8 N m.

6. Install the timing chain.

To install the chain without slack between each shaft (camshaft and crankshaft), follow this order: Crankshaft sprocket (A) -> Timing chain guide (B) -> Intake camshaft sprocket (C) -> Exhaust camshaft sprocket (D) ). The marks on each sprocket must match the timing chain marks (colored) when installing the chain.

7. Install the chain tensioner lever (B).

8. Install the automatic chain tensioner (A) and remove the installed pin.

9. After turning the crankshaft 2 turns clockwise (front view), align the marks (A) as shown in the figure.

10. Install the timing chain cover.

Using a scraper, remove the old sealant from the gasket surface.

Places where sealant is applied to the chain cover, cylinder head, cylinder block and frame with cross members should not come into contact with oil, etc.

Before assembling the chain cover, Loctite 5900H or THREEBOND 1217H liquid sealant must be applied between the cylinder head and block.

Parts must be assembled within 5 minutes after applying the sealant.

Note:
Band Width: 2.0L: 2.5mm; 2.4 l: 3 mm.

Install the timing chain cover.

Note:
Torque:
6x25: 7.8-9.8 Nm; 8x28: 18.6-22.5 Nm; 10x45: 39.2 - 44.1 Nm; 10x40: 39.2 - 44.1 Nm.

Firing and/or blowing of the timing chain cover must be carried out no later than 30 minutes after assembly.

11. Install the oil pan.

Before installing the oil pan, Loctite 5900H or THREEBOND 1217H liquid sealant must be applied between the cylinder block and pan parting surfaces.

ATTENTION
- When applying sealant, do not allow the sealant to get inside the oil pan.
- To prevent oil leakage, apply sealant inside the mounting bolt holes.

Install the oil pan (A).

Screw the bolts into several holes.

Note:
Torque:
M6 (C): 9.8-11.8 Nm; M9 (V): 30.4-34.3 Nm.

After assembly, wait at least 30 minutes before adding oil to the engine.

12. Install the cylinder head cover.

Excess sealant squeezed out on the top surface of the chain cover and cylinder head must be removed before installing the cylinder head cover.

After applying the sealant (Loctite 5900H), assembly must be completed within 5 minutes.

Note:
Band width: 2.5 mm.

Firing and/or blowing of the cylinder head must be carried out no later than 30 minutes after assembly.

Install the cylinder head cover bolts as follows: step 1: tightening torque: 3.9 ~ 5.9 N.m., step 2: tightening torque: 7.8 ~ 9.8 N.m.
