CAUTION: 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
camshaft timing belt if debris other than belt
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
72,000 km (45,000 miles). Do not use an oil
or coolant contaminated timing belt, cause
of contamination must be rectified.

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 mating faces on
camshafts.
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.Place gears inverted on a flat surface, with the
locating lugs on the gears positioned as
illustrated.3.Keeping the timing marks aligned, position
timing belt onto gears.
4.Position LRT-12-195 between the gears, turn
centre nut sufficiently to spread drive belt.
