7. Check chain wear by removing the chain tensioner plug, spring and pushrod, and removing the chain tensioner without altering the position of the
pistons.
The protruding part of the chain tensioner must not be longer than 15 mm. If it is, the chain must be changed.
8. Check the wear on chain sprockets and chain guide.
Chain guide wear must not be so great that the chain acts on the surface between the outer tracks.
If the surface between the outer tracks shows signs of wear, they must also be replaced and the chain changed in the usual manner.
Changing The Chain
1. Cover the area round the chain with a cloth and also secure the chain with cable ties on both sides.
2. Split the chain by pressing out a link using 83 94 637 Removal tool and then removing the link with a pair of pliers. Attach a cable tie to the end of
the old chain.
