Fluids change

I'm gonna change my transmission, transfer case & diff liquids, and have a few questions:

1. All three liquids are the same: SAE 75W-90. Is that right?
2. How is Loctite 5920 for a diff seal?
3. Is there any particular order I should follow when draining and refilling?
4. Maybe I should wait for warmer weather with this?

Re: Fluids change

Maybe warmer weather is in order, or you can drive it around for a few minutes to let the gear oil heat up. Keep the new stuff inside until you are ready to use it. As for the Loctite I don't know my numbers but, the Ultra Black or Ultra Blue is a good gasket maker. I would aslo suggest some BG MGC I have used this in my trans for years. I helps the gear oil climb the gears and everytime I change the lube it's does not look that bad. One of the race teams I worked on started me on it and no complaints yet. L8r,

Re: Fluids change

The transfer case takes ATF, not gear oil. The others take gear oil.

Re: Fluids change

Hmmm... Chilton says they all use SAE 75W-90. Doesn't that mean they're all the same stuff?

I hope you don't mean that you're gonna use the same oil all around [img]images/graemlins/confused.gif[/img]?

SAE 75W-90 is the viscosity grade for the gear oil.
Does your 93 YJ take gear oil in the T-case [img]images/graemlins/shocked.gif[/img]??
I thought that 93 year model they took ATF fluid....
Do you have a limited slip rear diff??... If Yes .. don't forget to put the additive (friction modifier) ... otherwise you'll fry the LS clutches ....
Maybe I'm wrong... and your set up is different.... but better safe than sorry [img]images/graemlins/grin.gif[/img]

In any case... 75-90 is a good grade for your type of climate... and summers are not excessively hot.... Down here I put SAE 90W-130... especially in summer.... (don't forget that Chilton and Haynes were written mainly with US &amp; Canada in mind)

Loctite makes a good gasket sealer

Re: Fluids change

Ahem... actually, that was the original idea. I emphasise was. Now I thinkit ain't gonna be that way.

I don't have limited slip diff (I guess, it's a stock 93 YJ), but I guess some additive in diffs couldn't hurt, right?

So, I should put the 75W-90 in the transmission, some ATF in T/C. And diffs?

Re: Fluids change

Ahem?.... [img]images/graemlins/chair.gif[/img] you just were about to ruin your t-case.... [img]images/graemlins/thud.gif[/img]

But anyway... [img]images/graemlins/grin.gif[/img] ...... yes put the 75-90 gear oil in your transmission (you have a manual ...right??) and in the diffs....
Drain t-case and replace with good quality ATF fluid...
The additive for limited slip...is not just any additive ...it's a very specific friction (viscosity) modifier formulated for this application only....
