Timing belt change - parts?

OK - so I didn't read the post below from Ringman well enough (see below...) - so i DID get soaked! Apart from that removing the belts was (pretty) straight forwards! The belts both look to be in sound condition but the bearing for the lower balance shaft is in very poor condition - I think that just the belts were changed on this car - not the bearings.

I removed the 22mm nut on the crankshaft with a rattle gun. Nothing to it.

The balance belt could be twisted on its longest length about 180 degrees - the timing belt about 110 degrees.

Ok.. The Big Question!!

I think I know how to put the thing back together... but I want to convert the car to a NON air conditioning compressor system by removing the AC compressor. Can I just remove the compressor and use a belt direct from the crank to the power-steering pump in its current position ** OR ** do I have to move the power-steering pump to a new position? Do the AC cars have the correct mounting hardware if I have to move the pump?

thanks, jimn~

It goes through a water jacket so when you take it out, you'll get soaked :-)

I think the only other thing that gave me trouble was that bl**dy PAS & AC arrangement.

I'd guess you can just remove it and stick the non-aircon belt on....was AJ able to help?

no - the ps pump will need to be moved for it to be driven direct from the crank belt location that currently drives the AC compressor...the question is does the setup I have contain this new mount point...

Doh..the PS pump is the top one! I thought AJ had done this...someone certainly has.

I need to check ePER but there's possibly a different bracket available...which flags up a vague memory of someone fabricating their own as the OE version was too much or unobtainable.

Same guy who fabricated his own inlet manifold I think...does that remind anyone else???

I wonder how it is done on an Integrale...

Hmmm, I wonder who knows......

It's a separate belt which runs between the AC pump and the PS pump which has a twin pulley on it.

I had replied to Jim & Gery83, but yes it is possible to do away with the AC pump. The PS pump then moves down slightly (I think taking the upper mount from the original AC pump mount, and the lower of the original PS pump mount).

The twin pulley on the PS pump can then be reversed (3 bolts) and it will be in line with the crank pulley.

You can't run a straight belt from the crank to the power steering pump in the original location. All the mounts are there for it to be lowered if junking the AC pump - nothing extra was needed (on a Coupe 16vt). It might be a bit of a PITA with it all in situ, but far from impossible.
