power steering pulley- Should it just drop on?
Permalink  
 


I removed the pulley from my old core power steering pump. It was the threaded/nut style with a keyway.

I'm attempting to install on the new pump which is the same style, but it won't go on, i can't start the pulley more than a 1/8 of an inch. There are no threads exposed for the installer tool to thread onto.    I really don't want to try and beat it into place, think i'm going to crush the pump.

 

I watched a couple you tube videos and looks like they are supposed to just drop on and the nut holds them in place. Is that right?

 

I'm looking at pulleys online and they all look like the one i have???

Are there two different types, a press on and a slip on?

I was under the assumption the other day yours was a press-on. I have the keyway style myself with the nut, it took a bit of force to get it on. I believe I tapped it lightly w/rubber mallet while tightening the nut.

Put the pulley in the oven on 350-400 degrees for a 1/2 hour or so and it should slide right on for you.

I tried beating it on with a rubber mallet and all it did was gouge up the inside bore of the pulley and shoot the keyway out.

Guess I'll have to buy another pulley.

I cannot get it on at all, so no way to push it on using the nut on the threads.

 I'll give that a try. Nothing to lose at this point.

Might not work if the surfaces are galled up.
Toss the pump in the freezer in a Ziploc bag.

You can heat it up with a torch as a last resort, like doing a wrist pin.

But you stand a chance of messing up seals/and or tempering.

Pulley went on after heating in the oven with some taps with a mallet, but it shot the keyway out the back. Can't get it back off again now without the stupid puller I already returned.

Then i dropped the whole thing on my foot and I damn near chucked it through my windshield.

Will revisit this later when I'm not liable to destroy things.

Hmm. All my pulley and pump stuff is aftermarket from March Performance and went together like PB&J. I've never had any good luck with Chevy OEM parts on that car(unlike the Pontiac).

Got it on now.

Rented the puller again and yanked it off. Hit the inside bore with a round file for a few mins and used a small jewlers file to open up the rear of the keyway slot a hair so it could get started easier. Pulley dropped right on like it was supposed to.

Gotta pick up a few washers tomorrow to shim the pump out a bit to line up with the crank pulley and I'll be in business!(as long as I didn't wreck the pump when I pounded on the pulley the first time or when I dropped it on my foot/floor.)
