I am putting a new power steering pump on my 6.2 conversion. I bought a used pump (just for the brackets, long story) and it had a double pulley on the pump. I ordered a new pump and it comes without the pulley so I ordered a pulley, it is a single pulley. I would use the used pump but either the pulley is bent or the shaft is bent. I am wondering how to get the new pulley on the new pump, it abviously has to be pressed on but I am afraid it will damage the pump in doing so, plus it doesn't appear to be a flat surface on the back anyway.

You need to buy the puller and installer tools, you can usually pick up the set at your local parts store. Unsure of cost as inherited a OTC set when I got my shop.

its a special puller for power steering pump pulleys, I just did my pump yesterday

Yeah, there is a special tool for that. If you can get the pulley off of the old pump without damaging it (tricky without proper tools, it is easy to bend) you can install it easily, just thread a bolt into the shaft and use it to press the pulley on.

I did not notice threading on the shaft, I have a new pulley but it is a single pulley, how do I know if I need the double pulley or the single?

The double pulley is for the air conditioning compressor belt on trucks with air. It is also a handy place to put a second alternator or an air compressor for onboard compressed air if you wanted. But if you don't have air (or it doesn't work) and you don't want to run anything else the single pulley is fine...

Its not on the shaft, is in the center, its 3/8 course thread.

I do have A/C so I need to find a double pulley. The center of the shaft looked like an allen head to me, I will have to check it out further to find the threading. How do you keep the shaft from turning when torqueing down the pulley?

You thread a bolt in the center, then use a nut and washer to draw in the in pulley holding the bolt. The kits use a thrust bearing to make it easier.

Since you do need the double pulley just go to one of the local parts places that has tool loaning... You'll have to put a deposit down on it, but they usually refund the whole thing when you return it. The tool will have instructions on how to do it.

Basically, I'm sure you noticed the little groove in the pulley hub. The special puller grabs that to avoid bending the pulley itself. I think I just used a funny three jaw puller I had laying around to get mine off. Then you just thread the bolt into the shaft on the pump and tighten it down. Clean out the inside of the pulley first so it goes on smooth first (I like to put a little grease in there too, seems to help). It shouldn't be too hard to tighten the bolt so you can pretty much just hold the edge of the pulley to keep it from turning...

Got my pulley today and will try to install it today using a bolt and large washer. I don't have to remove any pulleys because I am putting a new pulley on a new pump. I got a used pump but the pulley was bent, looked like they tried to get it off with a screw driver at the salvage yard.
I guess when the bolt starts getting hard to turn the pulley is far enough on the shaft to keep it from turning.
Also, do I put it on until the pulley is flush with the shaft? If you get that wrong it won't line up with the other pulleys.
Thanks I'll let you know if I have any problems

Yep, just put it on flush with the end of the shaft.

Thanks,will let you know if I have a problem
