Refit (continued)
- Refit the belt (10)on the pinion (12).
- Hold the belt(10)with tool [3].
- Position the belt (10)in the following order :
- The guide roller (11), the inlet camshaft pinion(9), the exhaust camshaft pinion (8), the water pump(5), the
tensioner roller (6).
NOTE :Make sure that the belt (10)is as flush as possilble with the outer face of the various pinions and rollers.
- Remove the tools [3]and[1].
T
iming belt.Adjusting the tension.- Turn the roller(6)in the direction of the arrow «b» ; using an Allen key at «a».
- Position the index «c»in its maximum setting at «d».
IMPERATIVE : The index «c» must stand proud of the notch «f» by an angular value of 10°. If it does not,
replace the tensioner roller (6) or the timing belt and the tensioner roller (6)
Bring the index «c»to its adjusting position «f»by turning the tensioner roller (6)in the direction of the arrow «e».
WARNING: The index«c»must not stand proud of the notch «f»: if it does, restart the timing belt tensioning
operation.
IMPERATIVE : The tensioner roller (6) must not turn while its fixing is being tightened up. If it does,
recommence the adjusting operation.
