REPAIR
CAUTION: Ease timing belt off gears using
fingers only. Metal levers may damage the
belt and gears. Do not rotate engine with
timing belt removed and cylinder head fitted.
Timing belts must be stored and handled with
care. Always store a timing belt on its edge with a
bend radius greater than 50 mm. Do not use a
timing belt which has been twisted or bent double
as this can fracture reinforcing fibres. Do not use
an oil contaminated timing belt. Although the belt
has a service life of 96,000 miles, 160,000 km, an
existing belt should only be refitted if it has
completed less than 48,000 miles, 80,000 km.

correct way.
3.Fit timing belt to gears, starting at the crankshaft
gear and working in an anti-clockwise direction.
CAUTION: Ensure the belt run between the
crankshaft and exhaust camshaft gear is
kept taut during the fitting procedure.

REPAIR CHECK CAMSHAFT DRIVE BELT
Service repair no - 12.65.17
CAUTION: This check must be carried out
at the service intervals specified and
whenever carrying out any repair which
requires the timing belt to be disturbed. Pay
particular attention for signs of belt splitting at
base of teeth.
1.Remove 5 bolts securing timing belt upper cover
2.Remove upper cover.
3.Using a socket and extension bar on the
crankshaft pulley bolt, rotate engine to allow the
timing belt to be inspected.
CAUTION: Do not use camshaft gears or
retaining bolts to rotate engine.
4.Check timing belt condition, renew any belt that
shows signs of oil contamination, cracking,
fraying or splitting at base of teeth.
CAUTION: Cause of oil contamination, if
present, must be rectified.
5.Clean timing belt upper cover.
6.Position upper cover.
7.Fit upper cover securing bolts.
