Camshaft timing belt - manual tensioner refit
CAUTION: When a replacement timing belt
is to be fitted, it will be necessary to fit the
tensioner spring and pillar bolt supplied
with the replacement belt to adjust belt tension.
1. Clean timing gears, coolant pump drive gear
and tensioner pulley.
CAUTION: If the sintered gears have been
subjected to prolonged oil contamination,
they must be soaked in a solvent bath and
then thoroughly washed in clean solvent before
refitting. Because of the porous construction of
sintered material, oil impregnated in the gears
will emerge and contaminate the belt.
2. Check correct alignment of camshaft gear
timing marks, fit camshaft gear locking tool
LRT-12-134.
