Hi,

I have removed the timing cover to check a few things and I tried my best to watch what I was doing and what came out. Well as far as I was aware I did, until I gave the cover a clean in the sink and at the bottom I found a very thin shim. I have looked at it and at the cover plus the parts book but I can't find it shown anywhere. Has anyone got an idea where it is from?

Thanks Eddie.

It`s an acquired skill which only a few of us have; to be able to assemble an engine and have parts left over.

50% of the motors I pull down are missing the shims doesn't seem to hurt that much.

Er... Norm... why are you having to pull them apart in this first place?!

Grumps, I should think the shim, if it was in the timing cover, is from one of the cam spindles. They are usually shimmed to compensate for differences in machining tollerences.

Michael, they are all blown up, busted pistons an big ends, no idea how many I have rebuilt over the years, but it is at an end, I'm sick of trying to gets bits made up,machined, repaired, in particular flogged out fly wheels, just not worth the problem they cause. Hopefully I will put the crank on this last one together in the morning, (picked up the wheels this afternoon) and bolt it all back together and it is out of the shed, I won't do any more

You're supposed to add shims as required to take the end float out of the cam spindles. The factory don't seem to bother and no harms seems to come of the end float. I suppose it might be a bit quieter properly shimmed up.
