Camshaft Gear Holding Tool
Maintain (no.4) in this counter-holding position and slacken the
EXHAUST camshaft gear bolt. NOTE: It may be necessary to fit a
breaker bar into the square drive provided in (no.4), to increase its
counter-holding leverage.
Remove (no.4) from the camshaft gear and slowly turn the camshafts to position the 'timing flats' to
achieve the correct alignment to the Setting Plate. This will allow the Camshaft Setting Plate to be
bolted down, using the securing bolts provided, in order that the Plate rests fully on the surface of the
cylinder head.
WARNING: The camshaft 'timing flats' MUST BE in correct alignment to the Setting Plates BEFORE
the securing screws of the Setting Plates are tighten down. The action of tightening the securing
screws of the Setting Plates MUST NOT be used to turn the camshaft to position the 'timing flats'
alignment, as damage to the cylinder head will result.
Repeat this procedure on the other bank of camshafts.
NOTE: Discard the old camshaft gear bolts – always fit new
camshaft gear bolts.
WARNING: Tightening procedure for camshaft gear bolts: For early engines, Jaguar instructs that the
EXHAUST camshaft gear bolt is tightened first, followed by the INLET gear bolt. However, for later
engines Jaguar and Land Rover instruct that the INLET camshaft gear bolts MUST BE tightened
before the EXHAUST gear bolts, and a WARNING is given that...failure to tighten the INLET
camshaft gear bolts first, will result in engine damage.
Fit new bolts and use (no.4) to counter-hold the exhaust
camshaft gear. Tighten the new camshaft gear bolts to specified
torque.
