Fitting .

Requirements:

l	The pistons should not be in top dead centre.

l	The camshaft wheels are immobilised with the camshaft fastener -T10016- in all the attachment holes on the camshaft housing to prevent it from involuntary turning.

–	Remove sealant remnants on cylinder head and camshaft housing with a commercially available sealant remover.

–	Prevent dirt and sealant remains from entering the cylinder block.

–	Clean sealing surfaces carefully. They must be free of oil and grease.

–	Apply a thin even coat of sealant onto the clean camshaft housing sealing surface as shown in the illustration (shaded area).

Note

Do not apply too thick a layer, as the excess sealant may penetrate the lubrication openings and damage the engine.

–	Ensure all roller rocker fingers contact the valve ends -1- and are clipped into their respective support elements -2-.

–	Screw in two threaded bolts (M6 x 70) into the cylinder head before installing the camshaft housing.

–	Carefully fit the camshaft housing vertically onto the cylinder head studs and dowel pins -arrows-.

Note

Ensure that no oil falls onto the contact surfaces on which sealant has been placed.

–	Tighten new camshaft housing securing bolts (evenly from inside to outside diagonally).

–	Take care not to tilt the camshaft housing. Tightening torque: 10 Nm

Note

Sealant must be left dry for approx. 30 minutes after installing camshaft housing.

Continue installation following reverse order for removing.
