Slacken the tensioer roller.
Turn the tensioner roller so as to be able to position the tool [4], with the aid of an Allen key placed at «a».
Turn the tensioner roller towards the right to bring it to the index «c» in position «b».
Peg the tensioner roller in this position in order to slacken the timing belt to the maximum.
IMPERATIVE : Never make the dynamic tensioner roller turn by a complete rotation.
Remove the timing belt (8).
Check that the rollers (9) and (10) turn freely (no tight spot).
