Anyone got the set of 3 from an engine that died for another reason ?

I think the crank nose, that has the first of the three gears, may exist in two versions, with/without AirCon, so be sure to get the right one

I have been told there are 2 varieties in existence......in simple terms....fat teeth and slim teeth, which were the later quieter version.

I have also been told my engine has a billet race crank ! ......perhaps worth over 4K !!!!

There are indeed.. Mine is the earlier noisier version.. I am wondering if I replace my cam sprockets will quieten it down a bit.

The cams are of course driven by the chain.....the chain runs off the step down gear from the crank which is not the same ratio or indeed the same set of teeth that drive the pumps.

I am not aware of any different chain/cam sprockets that might be quieter.

I'm looking just for the pump aux shaft gear

If anyone has one to sell please let me know

Not sure whether this is small or large teeth but this is the type I'm looking for
