9.Position LRT-12-175 to rear camshaft gears as
illustrated, remove and discard bolts securing
gears to camshafts.
10.Remove rear camshaft gears, timing belt and
special tool as an assembly.
CAUTION: Do not turn the crankshaft or the
camshafts while the timing belt is removed.
11.If camshaft timing belt is to be refitted, mark
direction of rotation on timing belt.12.Remove LRT-12-175 from camshaft gears and
remove timing belt from gears.
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.
