I have a 72 olds witch originaly had a 350 Ac but was switched to a 455 ac. I have had problems with the alignment of the power steering pump pulleys since I bought the car. Nothing is bent. There are two sleeves used to bush the pump out to the proper setting. I can not find these sold except at Year One and the diagram in my assembly manual shows two of them that are used. The bushing or sleeve in the front of the block is the longer one and the one down on the side of the block is shorter according to the manual. Is there a difference in the brackets between the 455 and the 350? The assembly manual shows the same assembly for both 350 and 455. Funny the discription in the Year one catalog says use where needed. Since this was all mixed together at some point before I bought the car maybe I should just toss it all and start over with the correct brackets.

All 1968-1990 Olds V8s use exactly the same PS pump brackets. The spacers are used because the Toronado front motor mount is sandwiched between the pump bracket and the front cover and the Toro differential mount is sandwiched between the PS pump bracket and the side of the block. RWD applications need these spacers instead. I take it you lost the ones on your 350 originally? Any wrecking yard 307 can source them.

 

The one on the timing tab stud is 3/4'' and the one on the driver's side bottom by the exhaust is 1/2"

Washers would work fine.

 

Thank you ,Thankyou,Thankyou!

On a similar note, when I got my engine back from getting rebuilt it had all new bolts. Is the one water pump bolt a stud with a nut made on it where the p/s mounts or just a bolt? And the timimg tab was also a stud with a nut made on it right?

 

Yes on both, you'll need those studs to mount your power steering pump.
RUN back to the machine shop and hope they've not thrown the old bolts away!

 

I bet if you they did you could post a wanted add and have 20 of them in a day! I got 50lbs of nuts and bolts from tear downs over the years.......Jerr

 

Thanks, I am going to call the engine shop today, If that doesn't work I'll post a request.
