Control
1. Check if there are any scratches on the crackers 9 and on the rod 3, and on the mating surfaces of the shoe and the plunger of the chain tensioner there are deep scratches. Replace damaged parts.
2. The elasticity of the tensioner spring must be within the limits indicated in Fig. Basic data for checking the tensioner spring; If the spring is less elastic, replace it.
