Position the intake camshaft so that the bolt hole in the gear is uppermost

A new seal can be pressed into place with a lever against the engine mounting

Carefully lever the camshaft seal out of the bore

Use an open-ended spanner to hold the camshaft whilst removing the bolt

5 Remove the four bolts and the right-hand bearing caps from the intake and exhaust camshafts. Remove the housing plug from its location in front of the intake camshaft, and remove the oil seal from the exhaust camshaft.

6 Secure the intake camshaft sub-gear to the main gear by fitting one of the service bolts into the threaded hole (see illustration 10.44).

7 Following the reverse of the tightening sequence (see illustration 10.36), loosen the remaining exhaust camshaft bearing cap bolts in 1/4-turn increments until the bolts can be removed by hand. Lift the bearing caps straight up and off.

Caution: As the centre bearing cap bolts are being loosened, make sure the camshaft is moving up evenly. If one end or the other stops moving and the camshaft gets jammed, start over by refitting the bearing caps. DO NOT try to lever or force the camshaft out.

8 Lift the exhaust camshaft straight up and out of the cylinder head.

9 Following the reverse of the tightening sequence (see illustration 10.33), loosen the remaining intake camshaft bearing cap bolts in 1/4-turn increments until the bolts can be removed by hand. Lift the bearing caps straight up and off.

Caution: As the centre bearing cap bolts are being loosened, make sure the camshaft is moving up evenly. If one end or the other stops moving and the camshaft gets jammed, start over by refitting the bearing caps. DO NOT try to lever or force the camshaft out.

10 Lift the intake camshaft straight up and out of the cylinder head.

11 Clean the oil off the camshaft follower shims, marking them I for intake and E for exhaust (and number their location) with a felt-tip marker and remove the followers with a magnetic tool, keeping the shims with their followers. Store the camshaft bearing caps, followers and shims so they can be refitted without mixing them up (see illustrations).

12 Position the intake camshaft in a vice, clamping it on the hexagonal section. Using a two-pin spanner, rotate the sub-gear clockwise and remove the service bolt from the threaded hole, then allow the sub-gear to rotate back until all tension is relieved (see illustration).

10.11a Mark the followers/shims and remove them with a magnetic tool

13 Remove the sub-gear circlip. The wave washer, sub-gear and camshaft gear spring can now be removed from the camshaft (see illustrations).
