Removal of Timing Chains and Gears
Primary Chains
Follow the procedure for "Checking Valve Timing", and fit the appropriate Flywheel Locking Pin and
the Camshaft Setting Plates on both banks of camshafts. Remove the crankshaft pulley following the
procedure detailed earlier. Remove the front timing chain cover and the VTT control solenoid housing,
if fitted. Commence work on the left-hand bank first as the primary chain from this bank is at the front
of the crankshaft gear and therefore must be removed first to allow access to remove the other
primary chain.
Fit (no.4) to the EXHAUST camshaft gear and use to counter-hold whilst slackening the INLET
camshaft gear bolt. Continue to counter-hold and slacken the EXHAUST camshaft gear bolt.
Remove the primary chain tensioner unit and back plate.
Remove the chain guide rails and the primary chain.
Carry out the same procedure on the right-hand bank.
Crankshaft Gears
IMPORTANT: The crankshaft gear is a two piece gear – make a note of the orientation of the gear
teeth. The teeth of the left-hand bank crankshaft gear (front) must be out of phase to the teeth of the
right-hand bank gear (rear).
