Hello,


My Turbo is leaking power steering fluid through the front seal, about one drop each second.
When running, it is pulling air into the pump and frothing the fluid causing it to overflow.


I found reasonably priced rebuild units, however they do not come with the v-belt pulley.


How do I remove the old pulley and mount it on the new pump?


Thank you

 

Seems like there must be a a key, pin or set screw on the base of the pulley to hold it to the shaft. Look for a flat spot on the shaft/pulley, if it has one that's where it will be. Might be hard to see if it's covered with dirt. Try probing around with a small screwdriver to see if you can uncover it.

 

Well, this post shows how much I know!

I went to replace my PS pump, and there's no key or hex screw. The shaft on the replacement pump (no pulley) is perfectly smooth.

Did they press fit these on?!

 

OK, so it looks like I'm going to have to buy a smaller 3-jaw puller than the one I have, and maybe get a PS pump from a scrapyard (I may have bent my pulley too much trying to 'persuade' it off).

After that, I'm considering grinding a flat spot in the new pump shaft and drilling out part of the pulley shaft hole so I can so I can fit a piece of metal in as a key (to keep it from slipping).

The shaft actually has threads inside so I should be able to fit a bolt to it with a bit of thread locker to keep if from flying off (unless it happens to spin so as to keep it tight).

Any advice is welcome!

 

If it has threads inside, you could attach a pulley with a slightly tapered sleeve and a bolt on the end to clamp it.

 

Thanks Pierce, that's what I was thinking. Haven't checked to see if it's going to rotate to keep it tight yet or not. If so then I'll use thread locker.

Fortunately I have access to a shop press, so I can get it back on. I'm going to have to put the whole assembly in the press to do it though. I'm going to put some wood down so the back of the pump casing isn't resting on steel (it's slightly curved) when I press it, my only concern is I might crack it when I press the pulley in.

They probably put it on that way though, as you can't get to the snap ring to open up the pump with the pulley on, so maybe I'm being a worry-wort.

 

Well, I went to the boneyard. Got a used pump w/pulley attached. Got it in, works fine.

Getting a pulley off one of these is IMO going to require special tools or sacrificing the dead pump (no core to turn in). I guess you could always turn in a pump from a boneyard.

Guess I'll cross that bridge if/when I get there.
