Power Steering Pump Rebuild

Pretty darn simple

Mopar in it's natural state

Disconnect the battery. ..always.
Pull the pump. 2 hoses and 2 bolts.
The tensioner bolt goes into a water jacket so prepare for that mess...

Now, first pull off the pulley.
I bought a Walmart puller - don't. It's crap. It stripped out and never even pulled the pulley. No problem, Walmart gave me my money back.
I rented one for free (deposit) at the parts store and the pulley came right off.

Next, take the tank off.

And here is the pump

Use a c-clamp to compress the cap a little and remove the retaining clip.

At this point, gently tap the pulley shaft and it all comes out of the casting.

The "rebuild" only consists of replacing a few o-rings and a seal ...I didn't photograph the o-rings....just remove one, go to you kit and find the match and put it in...couldn't get any easier.

Then reassemble it the way it came apart...there's not many parts, just take it apart carefully and it's very simple.

Note: there are 10 vanes in the rotating shaft...if you look carefully one side is square and one side is rounded...the ROUNDED side goes out...else you will prematurely were out the pump.

Painted.

Ran out of time. ..I'll reinstall it tomorrow.

Not to derail your thread but since you have such a great picture of what I need. In the first post,second picture the triangular bracket on the back held on with two nuts. I need on in case you may have one.

Ok can someone tell me if my TRW pump is a press on pulley? Looks like it but it has a large hex area at face of pulley?
Thanks.
67 273 cuda if that matters.

Yes, it's a press on...
The large groove on the hub of the pulley is where the 2 halves of the puller go around it to pull it off.
Down inside that hex is threads too....they're used with the tool to press it back on.

Thanks Jeff, so no need to worry about hex part in the teardown? I'll check at work tonight for pulley puller.

Yup...that hex played no roll in removal or installation of the pulley...
It MUST have a purpose because it costs money to machine it but I don't know it's purpose.
Anyone else know what that hex is for?

Ok so did the "loan a tool" for a pulley puller from parts store. "Worked" ok. Was bottoming out before pulley was off completely. Jammed a junk socket in there to take up the slack.
Worked perfect.
I'll start teardown shortly. I meant to do some research on adding the shim. Not sure where they are available.
Once I got pulley off, the seal looks real good with no signs of leaks.
May just leave that seal well enough alone.

^^^ That puller is different from what I used....but it works :thumbsup:
Just be sure to use the installer and do NOT tap it back on with a hammer.....

Jeff
 
Thanks Jeff yeah I was expecting a different type of puller, but this was as close as I could get.
Installer?? Uh oh...

Yes, the installer will screw into the center shaft and push down on the pulley. ..as you screw it down more and more, it pushes the pulley on the shaft....

No threads in the pulley, maybe on shaft under the seal?
The Saginaw has threads in the shaft the pulley goes on....results may vary!
You might have to get crafty to press it back on but just don't beat it back on with a hammer. ....

Anybody know how to press a TRW pulley back on?
(There HAS to be a way)

Jeff
 
Lol I thought I was losing my mind. I'll flip thru FSM and see if anything in there. We got a press here at work.

Yep that's what I was hoping for lol.
Judging by my FSM, looks like mine is the 1.2.
No installer needed, press on....carefully lol
