15.Noting that the front camshaft oil seals are
black in colour and the rear oil seals are red, fit
new camshaft oil seals using LRT-12-203 and
LRT 12-148A
CAUTION: Oil seals must be fitted dry. Do
not use tool LRT-12-148 for fitting seals.
16.Clean camshaft timing belt cover backplate
bolts and apply sealant, Part No. STC 50552 to
the first 3 threads.
17.Position camshaft timing belt rear cover
backplates to cylinder head, fit and tighten bolts
to 9 Nm (7.5 lbf.ft).
18.Fit spark plugs.
19.Clean rear camshaft gears and mating faces on
camshafts.
CAUTION: If sintered gears have been
subjected to prolonged oil contamination,
they must be soaked in solvent 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 timing belts.20.Place gears inverted on a flat surface, with the
locating lugs on the gears positioned as
illustrated.
21.Keeping the timing marks aligned, position
timing belt onto gears.
22.Position LRT-12-195 between the gears, turn
centre nut sufficiently to spread drive belt.

31.Remove LRT-12-175 from camshaft gears.
32.Remove LRT-12-197 from front end of exhaust
camshaft.
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.

CAUTION: Do not rotate crankshaft or
camshafts with timing belt removed.
CAUTION: Camshaft timing belt must be
replaced if cylinder head is to be removed or
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
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.
