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.

with clean engine oil, ensure ring gaps are
correctly spaced.
3.Clean bearing shell recesses in connecting
rods and bearing caps.
4.Fit piston ring clamp, LRT-12-204 to each
piston in turn and fit piston to its respective
cylinder liner ensuring that when fitted, arrow
on piston crown will be towards front of engine.
CAUTION: Do not push pistons fully down
bores at this stage.
