Power steering pump rebuild question

[landtank]

WIth my Hubbel glasses I thought I could see a difference.

My thought on this was that I'd throw in the seals and let the rest ride. The kit was cheap and everything else is submerged in oil so how much wear can there be?

I didn't need a puller as my gear came off with a little mallet help. The nut on the shaft spun right off with the aid of an air impact.

Tip: remove the rear cover with the pump facing down. That way you can remove the vanes individually and place them on the kitchen table with a specific orientation to be sure that they get re-installed the way they came out.

OK my input:

this job will be made a lot easier by pulling the drivers side (US) tire and attacking the problem through the rubber flap on the wheel well. The rubber flap should pull off (if it hasn't fallen off already :)

I know this because I did it twice in a week. The first time from underneath which was a pain but not impossible. The second time (story to follow) my dad comes in to see what Im bitching about, and pulls the flap up with the tire still attached and goes "why aren't you going in from here?"

I look at him incredulously and reply..... "uh.... I don't know"

try it... you'll like it...

now, my 2 centavos on a rebuild:

I rebuilt the pump on my 93 which was pumping all the PS fluid into the crankcase through the front seal. I was leaking no fluid from outside the pump. (rear seal)
I did everything right (AFAIK) and followed the manual. I remembered the snap rings mentioned, and could even tell which end of the vaines were *rounded*
2 days later on the trail it pumped all my PS fluid into the crankcase again..... I missed 1 1/2 days of a great trail ride due to it......

replaced with new Toyota OEM no problems since with MUCH locked wheeling

You might be OK rebuilding it, but I think it's good to know that some (me anyway) have NOT had luck...

sorry for the book :

I hope the 80 PS pump is easier than the FJ60 pump. The 60 pump had MANY small springs that would of went flying all over the house had I not been warned that is should be taken apart in a small room.

I found the 60 pump to be easier to rebuild. The slippers are kind of a pain, but the cover was a lot easier to install than the 80 pump.

Only one spring located in the high pressure port...not under any kind of pressure to where it will com out on ya.

So I took the smack to it and popped it off using a soft shovel handle. The reason that it was stuck was apparent once removed. The PO seems to have been in there before and used silicone or some other Make-A-Gasget type material in conjunction with the big orange seal. There's a notch apparently ground out of the side of the PS pump housing. I have no idea if this is normal or not, but it doesn't seem to be a "nice" factory groove. More like someone tool a small grinder blade to it. The picture below better illustrates the problem he was trying to fix. Question is...Is this normal? or some sort of Upgraded feature that allows the pump to blow that seal easier in case of failure? The reason I ask is that it just seems totally foreign to have a grinder around that area of the pump, and to have "accidentally" cut that deep of a groove.

Is this fixable with that Make-A-Gasget type stuff or is it too high pressure? What does a replacement housing cost?

On a brigher note, I did find two other seals that were shot...hopefully all this work we be worth something in the end. BTW...if you follow the FSM word for word, you'll forget a couple seals and the final snap ring. I caught the two seals, but had the hole thing back together before I noticed the snap ring sitting on my bench and had to pull the gears off again.

Thanks again.

I've been in Denver for 2 and 1/2 days gettin' learned up

I'll pull a new pump tomorrow and look at it. This one looks like a factory milling.

 

[Riley]

Not that I need one yet but anybody want to guess-timate the cost of the OEM unit?

 

[cruiserman]

SOR shows it at $310.

 

[cruiserdan]

I just looked at a new pump. There are no cuts of any kind around the ring.

Current list is $310.43, a smart shopper could fine one for about $232.82

Thanks Dan....I guess I need to talk to Rick.
