Camshaft LH: Installation

WARNING: This page is about a different car, the 2011 Jaguar XK and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Prior to installing the camshafts, position the crankshaft 45 degrees ATDC cylinder 1A to prevent valve/piston collision.

CAUTION: Make sure that the camshafts and camshaft bearing caps are installed in their original locations.

CAUTION: Evenly and progressively install and tighten the camshaft bearing caps.

NOTE: Lubricate the camshafts and the camshaft bearing caps with EP90 oil (or 75/90 viscosity oil will suffice) prior to installation.

Torque: 3 Nm

NOTE: Tighten the bolts in the indicated sequence.

Torque: 12 Nm

CAUTION: Only rotate the crankshaft clockwise.

Rotate the crankshaft untill the camshaft lobe on the valve being checked is 180 degrees from the maximum opening position.

NOTE: If the valve clearance is incorrect, continue to the next step. If the valve clearance is correct, continue to step 8.

NOTE: On vehicles without supercharger the inlet camshaft valve clearances cannot be checked.

Using feeler gauge check the gap between the tappet and the camshaft lobe and check against specifications table.

CAUTION: Do not use a magnet to remove the tappet.

CAUTION: Use the following formula to calculate the required bucket thickness. Original thickness + measured clearance - desired clearance = required bucket thickness.

Remove the tappet and measure the thickness.

NOTE: If a new tappet is installed then go back to step 1 of the install procedure.

Install a new tappet if required.
Using feeler gauge check the gap between the tappet and the camshaft lobe and check against specifications table.
