Tensioner — inspection, disassembly and assembly (VAZ-2121)

Disassembly and assembly. To disassemble the chain tensioner, remove the cap locking nut 1 (see fig. 2-55), clamp cracker 9 and spring ring 4, then remove plunger 7, spring 5 and rod 3 together with spring 8 and washer 6.

Assemble in reverse order.

Control. Check for burrs 9 and rod 3, and for deep scratches on the mating surfaces of the shoe and plunger of the chain tensioner. Replace damaged parts.

The elasticity of the tensioner spring must be within the limits indicated in Fig. 2-57; if the spring is less elastic, replace it.



Check for excessive wear on the shoe and guide; replace them if necessary.
