new drive gears, tensioner or coolant pump
are to be fitted. Camshaft timing belts must
be stored and handled with care. Always
store a camshaft timing belt on its edge with
a bend radius greater than 50 mm (2.0 in).
Do not use a camshaft timing belt that has
been twisted or bent double as this will
damage the reinforcing fibres. Do not use a

dust is found in timing belt covers. Do not
use a camshaft timing belt if partial engine
seizure has occurred. Do not use a
camshaft timing belt if mileage exceeds

NOTE: Following front or rear timing belt
refitment, it is possible that, after rotating the
engine and positioning the crankshaft pulley to
the 'SAFE' position, the timing marks on the
rear timing gears may be misaligned. This
misalignment is acceptable provided that the
timing belt refitting procedure was carried out
correctly.
1.Clean camshaft gears and hubs, crankshaft
gear, tensioner and water pump pulleys.
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.Fit hubs to camshaft gears and fit gears to
camshafts. Fit new bolts and tighten sufficiently
to allow gears to rotate without tipping.
3.Position timing belt to crankshaft gear.
NOTE: To prevent the timing belt from
disengaging from the crankshaft gear when
fitting, fit a suitable wedge between the belt and
oil pump belt guard.
4.Fit tool LRT-12-197 into each exhaust
camshaft in turn.5.Using assistance, rotate each exhaust
camshaft slightly and align timing marks on LH
and RH rear camshaft gears.

camshaft.
7.Fit tools LRT-12-175 to LH and RH rear
camshaft gears.
8.Rotate both front inlet camshaft gears fully
clockwise as viewed from front of engine.
9.Using fingers only, fit timing belt to gears,
starting at the crankshaft gear and working in
an anti-clockwise direction, keeping the belt run
as taut as possible and turning the camshaft
gears only a minimum amount anti-clockwise to
fit timing belt.
CAUTION: Gears must not be rotated anti-
clockwise more than one tooth.
10.Position an Allen key in tensioner backplate
and hold tensioner pulley against timing belt.
