Engine Rebuild (Part 14) - Camshaft Bearing and Pulley

Short and sweet this one........

I haven't found this operation in manual 814, but found it towards the end of Operation DX.231-4 in manual 518.

The camshaft pulley had been blasted with glass beads. I had checked it for any play in the rivets as I’ve read several reports of pulleys starting to break apart: replacing the pulley is an awkward job on a rebuilt car and involves removing the steering rack - so now was the time to check for wear and tear. Satisfied that it had a few more miles left in it, the pulley was repainted.

The old bearing collar was removed and I drifted the old bearing out with a suitably sized socket.

The collar was vapour blasted and a new camshaft bearing was fitted.  The new bearing was a looser fit in the bearing cap than the old one – so I gave the cap a small smear of threadlock before pushing the bearing home. The cap was refitted. 

When aligning the pulleys, the camshaft pulley can be shimmed to make it level with the HP pump pulley. My car had a shim so I put it back on for the moment.

The pulley was temporarily slotted in place.

I'm not going to bolt it up until I've aligned all the pulleys.
