Checking the technical condition of shock absorber parts (VAZ-2101)

After disassembling the shock absorber, it is recommended to wash all its parts with gasoline or kerosene and dry them. When checking, the shock absorber parts must meet the following requirements:

• the compression and rebound valve discs, as well as the relief valve plate, must not be deformed; the flatness of the bypass valve plate is allowed to be no more than 0.05 mm;
• the working surfaces of the piston, piston ring, rod guide bushing, cylinder and valve parts must be free of burrs and nicks that could disrupt the normal operation of the shock absorber;
• the springs of the rebound and compression valves must be intact and sufficiently elastic;
• the compression valve discs must be intact and not show significant wear;
• it is recommended to replace the oil seal with a new one during repairs.

Possible shock absorber malfunctions, their causes and methods of elimination are given in Table 17.
