Camshaft Setting Plates
In order for the camshaft timing to be correct, both Setting Plates
MUST fit flush on to the camshaft 'timing flats' and rest fully on the
surface of the cylinder head. If this cannot be achieved, then timing
adjustment will be necessary. Timing adjustment and applications
involving cylinder head /camshaft removal will involve removal /
installation of gears and timing chains. These applications require
the front timing chain cover to be removed, for access to gears,
chains and tensioners, and to remove the cover, the crankshaft
pulley must be removed.
Adjusting Valve Timing
The following procedure covers valve timing adjustment and also applies to setting up the valve timing
when installing camshafts, gears after cylinder head overhaul etc. Check that the crankshaft is in its
'timed' position and that the appropriate Flywheel Locking Pin has been inserted, as described in
"Checking valve timing" Remove the water pump pulley. Remove the front timing chain cover.
Remove the VVT solenoid housing from the inlet camshafts, if fitted. NOTE: In order for the camshaft
timing to be correct, both (no.3) MUST fit flush on to the 'timing flats' and rest fully on the surface of
the cylinder head.
To adjust the position of the camshafts to achieve this position the inlet and exhaust camshaft gear
bolts must be slackened.
Work on one bank of camshafts at a time. Install an (no.3) loosely
across the 'timing flats' on the camshafts. DO NOT tighten the
securing bolts of the Setting Plate at this stage.
Camshaft Gear Holding Tool
Fit (no.4) in to the holes in the EXHAUST camshaft gear and use it
to counter-hold whist slackening the INLET camshaft gear bolt.
