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.
Refit
NOTE: For torque values.See
Specifications, torque, Torque values
1.Clean timing belt gears and pulleys.
2.Clean crankshaft pulley.
CAUTION: If original belt is to be refitted,
ensure direction of rotation mark is facing
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.
4.Fit timing belt lower cover, tighten 3 bolts to the
correct torque.
5.Fit crankshaft pulley to crankshaft timing gear.
6.Fit tool LRT-12-059 to crankshaft pulley, fit 2
bolts to retain tool.

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.
