steering assist pump

Recommended Posts

My power steering pump is leaking badly. Last time i took apart one was 15yrs ago and i know for sure there is a large O-ring seal sandwiched between circumference of inner body and top part of pump which sit's in a groove of top section. Thing is i can't remember how i manage to separate the top section with shaft/bearing & pulley from the pan like body.

 Has anybody done this in recent times? Will appreciate any tips so i don't end up mucking up too much of it. Sadly i gave away all my extra pumps .

Pretty sure you have to remove the mounting points from back of the pump, and then the tank comes off.

Yes that's it, remove bracket and studs then thread in 2 bolts. Lay the pump on edge face down preferably on 2 blocks of wood and tap on the 2 bolts and out it comes.

Thanks Bean.

So was the tank seal the culprit?  It looks like a common GM style pump - is there a readily available reseal kit for it?

Yes it was the very large seal. I just went down to our local marine supplier with old square profile seals and matched what was closest to a wide selection of O-rings.

And yes it's GM design so it was easy to find a U tube repair video, here's link to it.
