The central gearbox of the rear axle, after being removed from the car for repair, is disassembled on a workbench 500-600 mm high in the following sequence:

The YaMZ-236M2 and YaMZ-238M2 engines are six- and eight-cylinder models of the family of four-stroke diesel engines of Avtodizel OJSC

Adjusting the tension of MAZ car drive belts

The drive of the water pump, compressor and generator is carried out by V-belts, on the reliable operation of which the normal operation of these units depends

The service life of the engine depends on the timely and thorough lubrication, as well as on the grade and quality of the oils and greases used

Replacing the piston rings of the YaMZ diesel engine of the MAZ car

Piston rings during engine repair are replaced in the following cases:

• - when the engine has run more than 150 thousand km;

The location of the gears of the drive mechanisms of the engine, subject to restoration or replacement in the process of repairing the engine, is shown in fig. 1

The crankshaft is steel, made by hot stamping. The shaft journals are hardened with high frequency heating

Removing the steering mechanism from the car

To remove the steering gear from the vehicle, do the following:

Power steering pump for MAZ vehicle with flow and pressure valve

The NSh-32U gear pump consists of a housing 6 (Fig. 1) and two gears placed in it: driving 7 and driven 9, rotating in bronze bushings

Model 182 diaphragm clutch (Fig. 1) consists of driving and driven parts, as well as parts of the clutch release mechanism installed in the clutch housing

Removing the power cylinder from the vehicle

Removal order;

- disconnect the hoses, after draining the oil from the tank;

Compressor capacity at 2000 rpm engine crankshaft - 201 l/min

Remove and disassemble the brake valve (Fig. 1) in the following order:

• - remove the brake pedal release spring and disconnect the brake pedal rod from the lever;

The engine power system includes components, parts and assemblies designed for thorough cleaning and uniform distribution of strictly metered portions of fuel over the cylinders

Plunger type high pressure fuel pump (high pressure fuel pump), driven by the camshaft through the fuel pump drive gear

The nozzle is designed to inject fuel into the engine combustion chamber in a finely atomized state

Fuel priming pump (fig. 1). Piston type, mounted on high pressure pump and driven by camshaft eccentric

The power and economic performance of the engine, as well as the reliability of its operation, largely depend on the thoroughness and quality of the adjustment of the parameters of the high-pressure fuel pump
