Camshaft timing belt - automatic tensioner - refit
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.
1. Clean timing gears, coolant pump drive gear
and tensioner pulley.
2. Check correct alignment of camshaft gear
timing marks, fit camshaft gear locking tool
LRT-12-134.
3. Check that crankshaft gear timing marks are
aligned with flange on oil pump - 90
°
BTDC.
4. Fit flywheel locking tool LRT-12-145, secure
with 2 bolts.
5. Fit timing belt tensioner ensuring that index
wire is positioned over pillar bolt and that
tensioner lever is at 9 o’clock position.
6. Fit a new tensioner securing bolt and tighten
bolt until it is just possible to move tensioner
lever.
7. Using the fingers only, fit a new timing belt over
crankshaft gear, then camshaft gears,
tensioner pulley and coolant pump drive gear
ensuring that the belt run between the
crankshaft gear and the exhaust camshaft gear
is kept taut.
8. Check that timing belt is positioned centrally
around gears and tensioner pulley.
9. Ensure inserts are fitted in timing belt lower
cover.
