Maintenance of a Kamaz car

General information about Kamaz vehicle maintenance

The scope of maintenance includes inspection and diagnostic, fastening, lubrication, adjustment, electrical and installation and dismantling work associated with checking and adjusting individual components and assemblies on special stands and equipment

If during maintenance there is doubt about the complete serviceability of a separate assembly unit, then check it with a special device or on a stand.

Maintenance of KamAZ vehicles (road trains) is divided into maintenance during the initial and main periods of operation.

Maintenance during the initial period of operation:

• - daily maintenance;
• - maintenance after the first 1000 km (service A);
• - maintenance after the first 4000 km (service B);
• - service 1 after the first 8000 km;
• - service 2 after the first 12,000 km.

Maintenance during the main period of operation:

Car maintenance frequency

• - daily maintenance;
• - service 1;
• - service 2;
• - seasonal maintenance (service C).

The main purpose of daily maintenance is general monitoring of the condition of units and systems that ensure traffic safety, and maintaining proper appearance.

During the initial period of operation, parts in the vehicle’s components are worn in, so when carrying out maintenance during this period, carry out preventive fastening and lubrication and cleaning work with special care.

Initial maintenance is carried out regardless of operating conditions.

During the main period of operation, maintenance work is carried out at intervals corresponding to the category of operating conditions

Frequency of vehicle maintenance depending on the characteristics of operating conditions:

Motor roads with asphalt concrete, cement concrete and similar surfaces outside the suburban area

Motor roads with asphalt concrete, cement concrete and similar surfaces in the suburban area, streets of small cities (with a population of up to 100 thousand inhabitants):

• - service 1: 4000 km;
• - service 2: 12000 km;
• - service C: 24,000 km.

Motor roads with asphalt concrete and similar surfaces in mountainous areas. Streets of big cities

Roads with crushed stone or gravel covering

Dirt profiled and logging roads

• - service 1: 3200 km;
• - service 2: 9600 km;
• - service C: 19200 km.

Roads with crushed stone or gravel surfaces in mountainous areas

Unprofiled roads and stubble. Quarries, pits and temporary access roads

• - service 1: 2400 km;
• - service 2: 7200 km;
• - service C: 14400 km.

Seasonal maintenance includes additional autumn work, which is performed once a year.

All types of maintenance are carried out within the time limits specified in the service book.

Lubrication

The name of the oils, quantity and frequency of lubrication are indicated in the chemical lubrication chart of the vehicle, and the location of assembly units and units that require periodic replenishment or oil replacement is shown in Figure 2.

Remember that the use of substitutes significantly reduces the durability of vehicle assembly units (for example, a power steering mechanism by three to four times) and is allowed only as a temporary measure.

When switching from one recommended type of oil to another, flush the gearbox with a mixture of 50% diesel fuel and 50% fresh oil intended for subsequent oil filling, cranking the engine for 5-10 minutes with the gearbox in neutral.

Fastening work

The list of maintenance operations includes fastening work, the implementation of which is mandatory.

To control the performance of fastening work, the article - Tightening torques for KamAZ fasteners provides a table of tightening torques threaded connections tightened during maintenance.

Features of repair work

Routine vehicle repair consists of eliminating any malfunctions and damage that are detected during operation or maintenance through repair operations associated with partial or complete disassembly of units, assembly units or their replacement, as well as the replacement of individual parts (except for basic ones).

The basic part of the unit is the most complex and expensive part (body, base, frame, block, etc.), to which all other parts are attached.

Before disassembling the unit (engine) or any assembly unit located on it, check the general condition of the unit (engine) using diagnostic equipment and collect as much data about it as possible.

This will help determine the cause of the problem.

For a faster and more thorough inspection, clean the unit (engine) from dirt and wash it before inspection.

Remove, transport and install the unit (engine) using lifting vehicles equipped with devices that guarantee complete safety of work.

When performing repair operations, be guided by the following general principles

Disassemble and assemble parts of any assembly unit or unit on a special stand or workbench, using special tools skill and equipment

Assemble all assembly units and assemblies in the reverse order of disassembly. Therefore, when disassembling, place the parts in a certain order.

Disassemble parts connected by welding, riveting or fixed fits only in cases where this is caused by repair conditions.

Unscrew the studs only when necessary under the conditions of disassembling the unit or assembly unit, when replacing the stud and part.

Before tightening the cylinder head bolts (if they were removed), remove oil or water from the threaded holes of the block.

Do not depersonalize pairs of parts that are installed on the engine only as a complete set:

• - main bearing caps with a block, connecting rods with connecting rod caps, plunger pairs of a high-pressure fuel pump, a piston with a cylinder of a manual fuel priming pump, a rod with a rod bushing of a low-pressure fuel pump;
• - driven and drive gears, main transmission of drive axle gearboxes.

Carefully separate the gaskets from the contact surfaces using a screwdriver; press out parts only with the help of tools, or if they are not available, use special drifts or light blows of a copper (wooden) hammer.

To check the technical condition of all parts after disassembly, clean them from dust, scale, carbon deposits, varnish deposits, rust, rinse and dry. Do not wash parts made of aluminum and zinc alloys in alkaline solutions.

Inspection of parts, start with an external inspection; to identify defects on critical parts, use magnifying glasses or a magnetic flaw detector. Demagnetize parts that have been tested using a magnetic flaw detector.

When inspecting, discard:

• - parts that have significant scuffing, chipping or chipping, or traces of burning;
• - parts with cracks on working surfaces and in places that experience heavy loads during operation (for example, cracks on crankshafts and connecting rods are unacceptable);
• - fasteners with thread damage of more than two threads;
• - bolts and nuts with worn edges, as well as screws with clogged or torn head slots;
• - cotter wire and lock washers with folding edges;
• - rubber parts that have lost elasticity;
• - hoses with cracks and delaminations;
• - pipelines with dents that reduce their cross-section, or with cracks at the flared ends;
• - crumpled brass couplings;
• - metal panels and tail parts that have dents, cracks and holes on the surfaces;
• - fuel tanks with dents, leaks, or damage to the coating or paint.

Before assembly, prepare all parts as follows:

• - clean the nicks and burrs on the mating surfaces of the parts;
• - restore damaged threads within acceptable limits;
• - weld cracks or cavities in unloaded areas of parts (for example, in the walls of water jackets and exhaust gas pipelines); after welding, clean the seams to give the part the proper appearance;
• - the parting planes in which the warping slightly exceeds the permissible level should be corrected by scraping;
• - check the water and oil cavities of parts and assemblies, as well as high and low pressure fuel lines for leaks;
• - remove the anti-corrosion coating used when storing parts;
• - wash the parts and assemblies of the high-pressure fuel pump, hand pump and injectors with clean summer diesel fuel, precision parts (plunger pairs, discharge valves and nozzles) with gasoline.

After washing, blow off the parts with compressed air.

Do not wipe fuel equipment parts with cleaning material.

Before assembly, lubricate sealing gaskets, threads in plug holes and threads in through holes with sealing non-drying paste, and impregnate felt seals with grease.

Ready for assembly means that all assembly units subject to restoration have been restored or replaced with new ones and are ready for assembly.

During assembly work, inspect each mechanism and make sure that nothing was missed during restoration.

Assemblycarry out under conditions that guarantee the cleanliness of the parts.

When tightening connections sealed with rubber gaskets, do not use too much force, otherwise the gaskets will be destroyed.

Tighten the threaded connections during assembly, ensuring the torques recommended in Tightening torques for KamAZ fasteners

When pressing rolling bearings, the tool must rest against the ring being pressed.

When installing oil seals and cuffs, use mandrels.

After repair of assembly units and replacing them on the vehicle, perform a run-in to ensure that all mechanisms and systems are in good working order and that they interact correctly.
