pulley alignment?

I see light at the end of the tunnel!! Finally, I have the 350 / 700r4 package installed, and picking up my driveline today. I'm down to installing the accessories, fuel line, radiator, TCC adjustment, shift linkage, etc. A previous owner decided to pull the A/C compressor and installed a different pulley setup. It worked ok before I removed the engine, but I discovered that the harmonic damper was not fully seated..perhaps to help in alignment. Anyway, please see attached pics - the power steering pulley alignment is off. Is there an offset pulley available? I know the eng is a circa 1978.

Any ideas - I do want to re-install a/c at some point, but now at this time. I just want to get her running.

Re: pulley alignment?

dumb question, but just maybe...

Is the pulley on the power steering pump fully seated?

Actually, I have no idea since it's the original setup. Water pump is for a 78chev pickup, since that's what matched up when I brought the old pump to the LPS. Which way should the power steering pulley install, right now the shoulder on the pulley is facing forward which might be backwards? But, if i reverse that, the pulley would move forward.

More detailed pics below...

Re: pulley alignment?

I think you may be right about mixing long & short water pump pulleys. The power steering pump looks like the correct one, but it looks like a long water pump in the top photo.

I have the same alternator mount on my truck and a long water pump. The power steering pump & brackets I have are from a later setup also, I would guess like a 75 Chevy ps pump on mine. That may be what you need, although I don't like mine and will be changing it. Hose routing is really bad on my setup and tears up hoses pretty fast.

I am going to a serp belt setup off a later model vehicle so that I can quite worrying about this, I have hunted & gathered numerous brackets & pulleys trying to move the alt back to the left side of the engine, so that I can hook up the factory air.

By the way, the PO on my truck had shimmed the alt out with washers trying to get everything to align correctly.

Re: pulley alignment?

Thanks for the quick replies...I love this board - best "tech support" out there

The water pump, balancer pulley, and the inside groove on the alt pulley line up.

Re: pulley alignment?

with aftermarket AC usually -- most likely inside pulley is power steering, 2nd pulley is alternator on drivers side, third toward radiator is AC on passenger side.

Re: pulley alignment?

I cant really tell by the pics but is the ps pulley set in just a little? Mine was once I switched to a long pump & used misc pulleys. All I did was remove the rear bracket bolt(the one on the motor mount) & put a washer or 2 behind the 2 bolts in the block. It worked just fine.

Re: pulley alignment?

I was wondering about this I have the exact same problem. I put the setup back on the motor that I got with it but for some reason my power steering pump pulley sits about 1/2 inch forward of were I need it to line up with the water pump pulley.
