Aggregate (overhaul) auto repair– is it complete or partial replacement units vehicle. Such repairs are necessary when the parts of the mechanism are worn out or severely damaged. Unlike routine repairs, during the overhaul process, faulty units are separated from the vehicle. In their place, new working spare parts or old spare parts are installed after complete restoration.

AVS Motors auto repair center offers repairs and comprehensive service cars German made. We professionally repair cars related to to the VAG concern: Volkswagen, Audi and Skoda, as well as Mercedes-Benz and BMW brands.

TYPES OF REPAIR OF VEHICLE UNITS AND COMPONENTS

Service specialists will quickly and efficiently perform the following types of work:

• Engine repair. May include repairing the cylinder block, oil pump, gas distribution and cooling systems. In the process of unit repair of a car engine, some elements are replaced, channels are cleaned and welding work is carried out.
• Gearbox repair (manual transmission, automatic transmission). Prerequisites for overhauling the gearbox may be a violation of the integrity of the housing, wear of bearings, couplings, gears, synchronizers and other parts. After the transmission has been restored, the transmission oil is replaced.
• Starter repair. Unit repair car allows you to eliminate starter problems such as sticking traction relay, breaks/shorts in the windings of stators and armatures, hanging brushes, breakage of the drive ring of the coupling, weakening of the drive buffer spring, burning and short-circuiting of the commutator plates.
• Generator repair. Overhaul of the generator is necessary if there are significant defects in the bearings, fasteners, pulley, charging circuit wires, voltage regulator, commutator, diode bridge and other elements. Most common reasons unit repair: long-term operation car, corrosion, excessively high loads.
• Transfer case repair. As a rule, it is carried out when there is an oil leak. May include replacing oil and worn parts: oil seal, flange, bearings. After repair, the unit is installed on the car, adjusted and centered.
• Steering rack repair. Aimed at eliminating problems such as leaking boot and rack housing; play, sticking or heavy movement of the steering wheel; tapping the slats. During unit repairs, the steering rack elements (shaft, pistons, bushings, rings, bolts, etc.) are changed or the entire unit is replaced.
• Repair of suspension parts: transverse and trailing arms, stabilizers, shock absorbers, silent blocks, steering knuckles, ball joints. The AVS Motors technical center specializes in aggregate repairs of suspensions on VAG cars of various years of manufacture.

STAGES OF CAR AGGREGATE REPAIR

Current car repairs are carried out by means of the vehicle fleet, and major repairs, as a rule, are carried out at repair enterprises - factories or workshops.

Troubleshooting current repairs of a vehicle in motor vehicle fleets is carried out through simple repair operations associated with partial or complete disassembly of vehicle units and components or replacement of units that require overhaul.

Current repair of a unit or assembly consists of replacing or repairing worn or damaged parts, except for the basic ones.

Typical works during current repairs are:

• for the engine - grinding in and adjusting valve thermal clearances, replacement piston rings, pistons, thin-walled liners, gaskets between the head and cylinder block, repair of cracks and holes in the cooling jacket, etc.
• on the chassis - replacement brake linings on brake pads, groove brake drums and brake linings on pads, replacement of kingpins, pin bushings of axle pins, springs, clutch discs, friction linings, gears in gearboxes, sliders and shift mechanism clamps, straightening and welding of frame cracks, replacement of springs, repair and restoration of body paint, repairs electrical equipment and engine power supplies, etc.

Car repairs are carried out using one of two methods:

• aggregate
• individual

With an individual repair method faulty units are removed from the car, repaired and reinstalled on the same car. With this repair method, the units are not depersonalized, and the vehicle downtime is determined by the duration of the repair of the most labor-intensive unit.

With the individual method, there is a significant period of vehicle downtime for repairs, as a result of which this method is used only in extreme cases when the vehicle fleet does not have a stock of replacement units.

Aggregate method of car repair consists of replacing faulty units with serviceable ones, previously repaired or new ones from the working capital. The unit (unit) is replaced in the case when troubleshooting directly on the vehicle requires more time than replacing it, and when repairs cannot be made between shifts. The faulty unit removed from the vehicle is repaired, after which it goes into the revolving fund.

The main advantage of the aggregate method is the reduction in vehicle downtime for repairs, which is determined only by the time required to replace one or more faulty units or components. Reducing downtime during repairs leads to an increase in the technical readiness factor of the fleet, and, consequently, an increase in its productivity and a reduction in the cost of transportation. Therefore, the Regulations on maintenance and repair of rolling stock road transport As a rule, an aggregate method of car repair is provided.

With the aggregate repair method, a car is sent for major repairs in the case when its frame, cab (truck), body ( passenger car) and most of the major units installed on it require this repair.

To carry out repairs using the aggregate method, it is necessary to have an irreducible fund of working units that satisfies the daily needs of the vehicle fleet. This fund is created both from the receipt of new units and usable units from written-off vehicles.

The scope of repairs carried out in a vehicle fleet using the aggregate method includes current repairs of the vehicle, including replacement and routine repairs of main units. IN bus depots also perform average renovation bus, determined by the need to restore the body.

Faulty units requiring major repairs are sent to repair facilities.

Repairs in automotive operating enterprises can be organized based on the use of ready-made spare parts, partial production and restoration of worn parts, and outsourcing of components and mechanisms for repair. Repairs of the vehicle and its components, as mentioned earlier, are carried out solely as needed.

The need for routine repairs can be determined:

• during the operation of the car and the subsequent application of the driver
• when inspecting the car by the mechanic on duty at the checkpoint upon returning the car from the line
• during the first or second maintenance of vehicles - by a mechanic or foreman

The need for major repairs of a vehicle that has completed a specified mileage is determined by a special commission chaired by the chief engineer; The composition of the commission is approved by the head of the vehicle fleet.

After inspecting the car, the commission draws up a report on its technical condition and gives a conclusion on putting it under major repairs or on further operation. In this case, the approximate mileage is determined, after which the car must be inspected again. The results of the commission's inspection are recorded in the appropriate section of the vehicle registration sheet. Faulty units, components and devices removed from the vehicle are transferred (via an intermediate warehouse) to the relevant production areas, where they are exchanged for serviceable ones. The head of the production site determines the nature and scope of repairs. The unit is sent for major repairs to an automobile repair plant by the decision of the production manager based on the conclusion of the head of the production site, which is documented in an act approved by the chief engineer.

The units are handed over for major repairs in accordance with the current technical specifications for vehicles and units submitted for repair. Units are accepted from major repairs after they have been tested on stands in accordance with the technical specifications for vehicles and units accepted from repair.

Each unit must have a passport issued by a repair company, and in a motor vehicle fleet a “unit repair card” is issued for the unit, where data characterizing its condition (new, repaired, etc.) is entered.

During operation trucks, they are subject to greater loads, and therefore require more frequent repair work than passenger cars. There are several types of repairs. Aggregate repair involves replacing one or more worn out/broken units.
