Sorry mate!
I just read back and saw yours is also 110mm.

This just gets stranger eh ??

Dennis, I will fit the alternator tomorrow (sunday) and let you know the outcome

Pel, Yes my pulley does measure 110 mm but thanks for the offer.

Well fitted the alternator today to check alignment and typically it is lines up between the crank pulley and the water pump. I could adjust it to go either way. The way to go I think is to leave the crank pulley alone and try to push the water pump hub almond it's shaft towards the engine. I found this image today http://www.locostbuilders.co.uk/viewthr ... ?tid=62754 which shows a P6 pump and the pulley is much nearer to the block than mine. I can only think that it has been moved along its shaft. Any comments?

Also noticed on above photo link that the balance rim on this crank pulley is on the radiator side. Is this correct as mine was fitted to the inside edge. How important are these rims?

Both Pel and myself said earlier that your water pump pulley looked too far away from the pump body.
Does the centre shaft of your pump protrude 4-5mm beyond the boss of the pump. It normally does to provide location for the fan.
If it is less than this amount then maybe you could push the boss further on to the shaft.
But I can't say if pushing the boss further onto the shaft will cause the assembly to jam!!!

Yes shaft does protrude, can't say how much but enough for a fan to slide over. Did we not compare measurements of pulley from pump face and find them the same? Is your pulley as near to engine as the photo in link?

The weights in the balance rim are matched to a particular engine in the factory as a final trim to the basic balancing. If the crank is not paired to the rims then it's unlikely that balancing will be correct if a different rim is used.
The rims were used to trim/adjust the balance of the engine at the factory but they also provide safety retention of the harmonic balance ring should it become detached. Many don't bother to install the rims.

Thats how my pulley looks and sits close to the suction pipe

I've just dug out my old p6 water pump pulley,


Is your pulley the same as this ?

Thanks for everyone's input but I am now sorted. I managed to push the buick pumps pulley boss along its shaft allowing me to line all the pulleys up.

New topic will be regarding the distributor. I will start a new topic.

Thanks again
