Destroyed Power Steering Pulley

[70grande]

So I recently got a new Power Steering pump and I needed to take off the pulley to get to it. I went to Harbor Freight and bought a Gear/Pully Puller. to get it off.
I screwed it down and had to apply so much force to get the pulley off that it completely destroyed the pulley. What idiotic mistake did I make and where can I get a new power steering pulling (in a decent amount of time cause its the only car I have to drive).

Did you use a tool like this?
Power Steering Pulley Puller OTC4530

You need this to remove and install. It can be a real pain even with the tool, and have seen the tool broken getting stubborn pulleys off.

You may be able to rent this from your local parts store.

Barn has linked to the proper tool for this job. If you use any tool that touches the pulley in any way other than the machined hub, you will destroy it, guaranteed. I have removed scores of these, even ones from abandoned parts cars, and they always come off intact, because there is no stress to the pulley itself.

The power steering pulley is screwed on. Not pressed. Left handed threads.

My 68 pulley was pressed on and required the tool Barn pointed to. Did they switch to screw on in 69?

The power steering pulley is screwed on. Not pressed. Left handed threads.

Wanna bet?

Last one I tried to remove was screwed on. It had an allen socket on the shaft to hold backup.

It's not supposed to, that screw hole is for the installation/removal tools. All I've ever seen is conventional RH thread, though.

The earlier Eaton pump had a tapered shaft with key and retaining bolt, but the Ford-Thompson was press-on.

No doubt some are pressed on, some screwed on. The only one I removed the pulley from was screwed.

Well thanks all for the input, I went to autozone to rent the part and it came off (although it still put up a fight) and it was definitely pressed on, not threaded. Now I just have to drive out to NPD's warehouse and buy myself a new crome pulley! I have a bad feeling that I am going to spend way more than I want to though since they have a whole warehouse full of everything I need....

Unless it's a new item, they don't have any 70-73 PS pulleys. A used one would be quite reasonable, though.

Ha damn...I really wish I had read that last comment before I drove and hour to get there and buy a chrome pulley, drive back, realize it didn't fit and then do the drive again to return it. Oh well I got one on ebay.

All the Ford power steering pulleys I have seen were pressed on, and they all had the hex-shaped hole in the pulley shaft. A convenience for machining or removing/installing some of the internal parts when rebuilding?

I have never seen a threaded-on Ford power steering pulley.
