It is much easier to repair and maintain a VAZ 1111, having the proper knowledge. The materials on the site will allow you to find a repair manual for any part for an Oka car in the form of a video or photo report. The video instruction will demonstrate how the repair procedure should be performed and will exclude the possibility of erroneous actions. As for the photo report, it is accompanied by textual explanations that make it an excellent guide for newbie owners.

For drivers of the VAZ 1111, basic knowledge about the most frequent procedures during the operation of the car will be useful. According to statistics, the owners are most interested in replacing the Oka thermostat. The reason for this is the frequent breakdowns of the part in a harsh climate. The next in popularity will be: replacing the timing belt on the Oka, replacing the Oka pump, and also replacing the fuses in the Oka model. Some of the procedures should be done prophylactically, after an annual diagnosis. Heavy road conditions often lead to breakdowns in the braking system or transmission. In this case, the problem will be solved by replacing the brake pads on the Oka and replacing the clutch on the Oka. Knowing the algorithm, the nuances of the repair work and the list of necessary tools, you can fix the malfunction in a timely manner without outside help.

Additional information for those who want to carry out repairs to the Oka model with their own hands will be provided. Experienced vehicle owners or technicians will provide a comprehensive answer to assist with part replacement, diagnosis or repair.

The history of the VAZ 1111 "Oka" model

Despite the fact that the development of the model began in the late 70s, the production of the Oka model began only in 1988. The place for assembling the structure was the Yelabuga passenger car plant. Soon, production was transferred to Serpukhovskiy AZ and AvtoVAZ.

In 1995, the production of Oka stopped at Avto VAZ, but ZMA and SeAZ continued production. In parallel, the model was improved by installing a new type of engine - a 33-horsepower 2-cylinder engine with a volume of 0.75 liters (before that, a 2-cylinder, 0.65 liter and 29 hp was used). The novelty received a prefix to the name and ** was sold as VAZ 11113 **.

In 2006, for a number of reasons, the production of the VAZ 11113 was discontinued. The main one was the unprofitableness of the work that would be needed in order for the car engine conforms to the new Euro-2 standards.

However, the new owners of SeAZ found a way out of this situation. They supplied the car with a Chinese 3-cylinder injection engine with a displacement of 1 liter and a maximum power of 53 hp and a 5-speed gearbox. The novelty became known as SeAZ 11116. She received a lot of modifications, among which were cars for the disabled, vans and even station wagons.

In 2008, the plant stopped production of the Oka, but after 5 years it announced that it was planning major changes in the model, which would be presented in 2020.

VAZ-1111 (Oka) 1998-2003. Car repair and maintenance manual

VAZ 1111 (Oka) 1988-2003

General information about the car.

3-door 4-seater extra small hatchback with transverse engine and front-wheel drive. The production of the Oka was started in 1989 at the Volzhsky Automobile Plant. The engine is a two-cylinder with a working volume of 650 cc, in 1997 it was increased to 750 cc. volume. At present, the production of Oka cars has been transferred to the Kama Automobile Plant, as well as the Serpukhov Automobile Plant. In addition to the basic models KamAZ-11113 and SeAZ-11113, manual options are offered for disabled people. Due to its very low price, it is of interest for export.

This small car was developed at the Volga Automobile Plant for "corporate" production at three factories - VAZ, KamAZ and SeAZ (in a disabled version). It has been produced at the Volga Automobile since 1990.

General data VAZ 1111 OKA

“Oka” is a light front-wheel drive vehicle with a transverse arrangement of the power unit, designed for operation on paved roads. The car is designed for operation at ambient temperatures from –40 to +45 ° С.

The Oka family of cars includes two basic models: VAZ-1111 and VAZ-11113, which differ in the engines installed on them. The car body is an all-metal, load-bearing, three-door, hatchback type. The third door is located at the rear of the body and is intended for loading luggage. For the transport of bulky and long loads, the rear seat can be folded down, thereby increasing the volume of the luggage compartment.

Engines - two-cylinder carburetor: VAZ-1111 - with a working volume of 0.65 liters and VAZ-11113 - with a working volume of 0.75 liters. The vehicle is equipped with a hydraulically actuated dual-circuit service braking system, which increases its safety. The braking system is diagonally divided into circuits. Front disc brakes, rear - drum. Thanks to the front-wheel drive configuration, the car has improved handling characteristics compared to rear-wheel drive models, especially when cornering and on slippery roads.

Currently, the car is produced by the Kamsky and Serpukhovsky car plants.

Ignition system
Spark moment sensor:

1 - holder of the front roller bearing; 2 - sensor support plate; 3 - screen; 4 - the spring of the weight of the centrifugal regulator; 5 - weight of the regulator, 6 - driving plate of the centrifugal regulator; 7- oil seal; 8 - roller; 9 - clutch; 10 - bushing of the rear end of the roller; 11 - driven plate of the centrifugal regulator; 12 - vacuum regulator; 13 - connection for vacuum supply; 14 - thrust; 15 - contactless sensor (Hall sensor); 16 - case; 17 - a block of wires of the Hall sensor; 18 - cover; a - scheme of the centrifugal regulator; ἁ - ignition timing.
Details of the spark moment sensor:


1 - clutch; 2 - case; 3 - vacuum regulator of the ignition timing; 4 - stuffing box; 5 - contactless sensor (Hall sensor); 6 - the driving plate of the centrifugal regulator; 7 - weight of the centrifugal regulator; 8 - roller of the driving plate; 9 - spring; 10 - driven plate of the centrifugal regulator with a screen; 11 - lock washer; 12 - sensor support plate with bearing; 13 - bearing lock plate; 14 - front bearing holder; 15 - cover.
The ignition system is non-contact. Consists of a spark moment sensor, switch, ignition coil, spark plugs, ignition switch and high and low voltage wires. The spark moment sensor is of type 5520.3706 (until 1989 the sensor of type 55.3706 was installed) with built-in vacuum and centrifugal ignition timing controllers. It sets the moment of sparking depending on its initial setting, the number of revolutions of the crankshaft and the load on the engine.
The reading of the control pulses is based on the Hall effect. For each revolution of the crankshaft, there is one impulse (for each revolution of the camshaft - two). The initial ignition timing for the VAZ-1111 engine is 1 ± 1 ° to TDC, for VAZ-11113 - 4 ± 1 ° to TDC. You can check the performance of the Hall sensor with a voltmeter by connecting it between the terminals of the green and white-black wires. Slowly rotating the roller of the spark moment sensor, we follow the readings of the voltmeter. The voltage should change sharply from the minimum (no more than 0.4 V) to the maximum (no more than 3 V less than the supply voltage). If the steel screen with slots touches the sensor (determined by a slight jamming or scratching sound during the rotation of the roller, as well as after partial disassembly of the spark moment sensor), check the axial play of the roller (no more than 0.35 mm, adjustable by selecting washers) and the fit of the screen on roller.
Replace the assembly if necessary. A defective Hall sensor cannot be repaired and must be replaced with a new one (except for a wire break between the sensor itself and the block on the spark moment sensor housing). You can roughly assess the serviceability of the vacuum regulator directly on the car. With the engine running, disconnect the vacuum hose leading to the regulator from the carburetor fitting. If you now create a vacuum in the hose (you can use your mouth), the engine speed should increase, and when the vacuum is removed, decrease again. The vacuum should be maintained for at least a few seconds if the hose is pinched.
Visually, you can make sure that the vacuum regulator is working properly by partially disassembling the spark torque sensor (see "Removing and disassembling the spark torque sensor", p. 86) and applying a vacuum to the inlet fitting at the regulator. In this case, the screen of the sparking torque sensor should be rotated by an angle of 10 ± 1 °, and when the vacuum is removed, it should be returned without jamming. Accurate testing and tuning of the vacuum and centrifugal ignition timing controllers is carried out at special stands. It is not recommended to do this at home. If the vacuum regulator fails, it is replaced; if the centrifugal regulator fails, the spark moment sensor is replaced.

The switch type 3620.3734, or 36.3734, or HIM-52 opens the power supply circuit of the primary winding of the ignition coil, converting the sensor control pulses into current pulses in the ignition coil. The switch is checked by an oscilloscope using a special method, if you suspect a malfunction (engine interruptions, shots at the muffler), replace it with a known good one. Do not disconnect the switch connector while the ignition is on - this can damage it (as well as other components of the ignition system). Ignition coil - two-lead, dry, type 29.3705 - with an open magnetic circuit, or type 3012.3705 - with a closed magnetic circuit. Data for verification: resistance of the primary winding at 25 ° C - (0.5 ± 0.05) Ohm, secondary - (11 ± 1.5) kOhm. Insulation resistance to ground - not less than 50 megohms. Spark plugs - type А17ДВР, or А17ДВРМ, or their imported counterparts (with interference suppression resistors with a resistance of 4-10 kOhm). The gap between the electrodes should be within 0.7-0.8 mm (checked with a round wire probe).

High-voltage wires - type PVVP-8 with distributed resistance (2000 ± 200) Ohm / m or PVPPV-40 with distributed resistance (2550 ± 270) Ohm / m. Do not touch high-voltage wires while the engine is running, as this may result in electrical injury. It is also forbidden to start the engine or allow it to work with a broken high-voltage circuit (wires removed) - this can lead to burnout of insulation, failure of electronic components of the ignition system. Ignition switch type 2108-3704005-40 or KZ813 with anti-theft locking device, interlocking against re-starting the starter without first turning off the ignition. When the key is turned to the "ignition" position, voltage is applied to the control input of an additional relay of type 113.3747-10, which, in turn, supplies voltage to the ignition coil and the switch. This relieves the ignition switch contacts (see also Electrical Equipment).
