I need the proper LHM pump tensioner bolt for a PRV6.

Does anyone have a spare?

which part are you missing, the bolt that sits in the cup on the rear rocker cover or the clamp part that this bolt threads through and is used to lock the pump bracket off when tensioned?

Both bolts. My car came with no tensioner bolt at all.

I can't quite work out how the bolt works properly. As the tensioner bolt applies tension the bolt cants over. How does the horizontal bolt stay horisontal?

This begs another question.
Which end is the tensioning bolt fitted, the inboard end or the belt side?

Tensioning bolt is on the belt side, locking nut is the other side and part of the pump mount, it is a variation of the standard H1 pump tensioner setup but the whole cradle is levered off the rear rocker cover, i will get a picture of mine.
Not sure i have one spare but Paul might.

Thanks. The parts guide depicts it reversed. I thought it was odd.

The flange the tensioner bolt rests down onto is partially broken off, there is no cup at all, so I'll have to look into sorting that. I think I'll be able to make a bolt set, otherwise I'll make a cantilever tensioner tool.

Not sure if 2.1's were the same but the 2.0i cradle had a 1/2" socket in so you could use a 1/2" breaker to tension the pump while you did tightened the lock nut, that never had to be that tight though.
I think I have come to the same conclusion though, a heavily loaded auto tensioner would solve any slippage problem if used it conjunction with a longer belt, something that springs to mind is a K series rover engine cam belt tensioner bolted to a custom bracket.

I've bodged together a tensioner bolt assy. It isn't pretty, but it works well.
