Would've rebuilt the factory pump, if the pump was already in there. but it was already replaced with a duralast one so that's what I'm dealing with.

So basically I uninstalled the bad one and reinstalled the "new" one. anyway, it still leaked even with the new one. But here's where I'm confused. The new pumps come with 2 copper crush washers, and 2 O rings. the 2 crush washers obviously go on the banjo bolt, and one of the O rings goes on the reservoir. but where the hell does the other one go? I literally cannot figure this one out, and being that its been a pain in the ass to take apart almost 4 times now. I cannot for the life of me figure out where this O ring goes. even looking at an FSM there's no clue as to where the O ring goes.

Any help?

Also, I took the old one in to be swapped for a new one and this one didn't even come with a backing plate. Its 100% sealed, so what's the backing plate for, anyway?

Here's my pile:


Here's the back seal to the pump w/ no plate.


Here it is w/ the plate. Is it even required?:




Here's the two O rings that come with the new pumps. the smaller one is the reservoir o ring. but what the hell does the bigger one go to?


This is the only location I could find that looks like an O ring goes into, but its to the banjo fitting, and serves zero purpose since it doesn't even "seal" anything.


Here's the shaft, all sealed:


Here's the pump sitting as itll sit in the truck.


Someone lend me a hand. Tired of bashing my head against a wall.

The extra o ring could be for another application .

I would bet that pump is used in a few vehicles.

Is the back plate needed for a shim in your application ??

MaK92-4RnR

as far as I know, the back plate does nothing but protect the O ring and the back seat. that's it.

Does an O ring go on the banjo bolt?

Looking at this:

theres an O ring that goes on the pressure port union? but I'm confused on how it goes, because the pump comes with 2 copper crush washers.

I just finished installing another new pump and it still leaks. I'm doing something wrong here, I cannot for the life of me figure out this last O ring. I've literally come a master at removing/installing a power steering pump on a 3vz. can someone just tell me where this damn O ring goes?

Just where does it keep leaking ??

All these pumps failed the same place??

Banjo fittings most often use crush washers .

Is there a space machined for a o ring on the pump side of the fitting so it would go under the washer against the pump ??

MaK92-4RnR

honestly, I cant tell where it leaks because of how much ATF has accumulated under the truck and I have zero desire to clean one bit of it because of how much of a POS this truck is being right now.

look at that FSM page. it says theres an o ring that goes on the banjo. but where? it doesn't even say it uses crush washers.

That is not your banjo bolt fitting that gets that o ring.

That o ring goes behind the fitting the banjo bolt threads into .

looking at the 92FSM it shows the banjo bolt crush washers the o ring for the reservoir tank .

Unless your pulling that pressure port fitting out I can`t see a need for a second o ring.

Most pumps I replaced removing that fitting was not needed perhaps on yours it is.

Good luck

there's zero excuse for this thing to be leaking then. everything has been replaced on the damn thing except for hardlines and the steering box.

It has zero air in it, but it still continues to drip.

So basically what you're saying is pull the banjo bolt again and it goes inside where the banjo bolt threads into?

Only if you needed to install that part on the pump you just installed.

Seems like your getting a bunch of bad quality units.

it comes back to just where it is leaking.

Is it a connection you made ??

Is it something done poorly in the rebuild or manufacture??

all you should need to worry about is the reservoir tank the banjo bolt connection the return hose .

Could be a pin hole in the housing could be the pressure hose has a pin hole.

Could be the shaft cut the seal when it was installed

Without knowing where it is leaking you have no idea what is wrong .

With the quality of China built parts who can say.

I have had pretty good luck with Napa parts knock on wood.

just wanted to say I resolved the issue. that O ring apparently does absolutely nothing. I don't even know why it comes with the kit. I swapped the new pump on there and it hasn't leaked out since. Its been going strong with the steering control valve plugged, as well.

Appreciate you dealing with my patience, man. I lose my cool sometimes when I know I do things right but they don't work. haha

Glad you got it fixed a bunch of poor rebuilds.

So many times hardware kits are used in several vehicles so you get a few parts extra.

Not near so bad as putting extra gears in with the transmission in the parts washer.

when you say you plugged the steering control valve, do you by chance mean the air control valve that is connected to the ps pump or steering gearbox?

MaK92-4RnR

nope. the valve that protrudes out of the bottom of the steering pump and has vacuum lines that come up to the intake manifold. plugged that.

93dripper

Yes that is referred to as the p/s pump air control valve.. there is another control valve on the steering gear box as well. Anyways, I just replaced the part you were referring to and cost me $120 at AZ. it started leaking (a couple ounces a day) heavily after I replace the p/s pump and lines.


When referencing the part in the Toyota Service Manual I noticed that part of the valve is labeled a 'non-reusable part'. So anytime it is removed it is suggested to replace (only part of it). I also heard that the plastic half of the valve tends to crack or warp due to long-term heating and cooling.


Bottom line 120 bucks= a clean driveway, but if it ain't leaking for you now, then none to worry.
