Power Steering Q

[strickli]

Time for a total newbie question...newbie both to LC's and this site...

I got an '86 FJ60 about two months ago, and have been going through the parts that have been neglected and are failing...so far, the starter and the radiator. Next up is the transmission seal (and clutch while they're in there)

[FONT=Verdana, Arial]Anyway, the old (I believe, original) power steering pump died late last week, so I replaced it with a rebuilt pump core. My problem now is that the new core is leaking fluid almost as fast as I put it in.[/FONT] [FONT=Verdana, Arial]The problem seems to be where the mounting bracket for the resevoir meets the pump in the front...fluid is seeping out the lock washer on the mounting bolt (which leads to the inside of the pump). I'm not missing any parts, and it's assembled the same as the old pump. I'm leery of cranking down the bolt any harder.

[FONT=Verdana, Arial]Does anyone have any reccomendations on some sort of sealant goop, or should I remove the lock washer and use a rubber gasket?[/FONT]

This image is ripped off of CoolCruisers.com...pretty much the same pump, exactly the same resevoir. This pump, however, has a different bolt that holds on the resevoir (different from the other through-pump bolts, black in this photo). The one I have has 6 identical bolts (like the gold ones in this photo).

Thanks for your help...

Are you using ATF (automatic Transmission Fluid/Mercon Dextron III) or power steering fluid? Make sure your using ATF.

Do a search on this!

I Think there is a write up on this exact thing. If I remember correctly there is something about the length of a bolt that is the issue.

DON'T LET THAT THING LEAK ON YOUR SMOG PUMP!!
Good luck,
Toad

Yep, bolts are an issue. AFTM pumps usually come with a new O ring to seal the resivour to the pump.

You can chse your tail a long time with this. If you must stay smogged then only use an OEM pump. Remans leak down on the smog pump and kill it. If you just like changing pumps and are desmogged then buy aftermarket.

If you want a pump that works a long time then buy OEM. WHat is your time worth? I have installed 100+ pumps; buy OEM!

Each of the six bolts uses an o-ring to seal against the pump body. Although the schematic doesn't show it, there are two bolt sizes that are used (bolt 44329). Five "short" bolts and one bolt that is 2mm longer. The length is there to account for the thickness of the reservoir bracket, and still allow the o-ring to seal. The bolt that is installed in the 12 o'clock postion is probably a short bolt instead of the needed long bolt. It's not clear whether these bolts are available from the dealer. SOR shows them as no longer available. You might try removing the washer. That could position the o-ring inboard enough to allow it to seal. Just another reason to pay the big $$ for the toyota factory pump.

Another suggestion, is to return the pump for a replacement. It's fairly certain that this one was rebuilt improperly and should be still under warantee?

That's what it was! I thought the bolts were sealing with the bolt head, but they're actually sealing with the shoulders. When you add the 2mm resevoir bracket, the shoulders on the 12 o'clock bolt can't seat, and thus, massive leakage.

S&S1stCruzer: No, I am *not* using AT fluid, but I will now.

Toadhopper: Unfortunately, too late. The smog pump is pretty much soaked, so that'll probably fail pretty quickly. And in Central TX, I've gotta stay smogged (at least for 2 more years, until the car gets grandfathered).

dd113: Lesson learned: always buy OEM parts. Foolish me.

I've ordered an OEM pump, and will return the aftermarket POS.

Thanks guys!
