Rear Seal / Oil Pan
 

(87 YJ 258)
I got very tired of oil messing up my driveway and decided to tackle
the oil pan gasket and half way through that I came to my senses and
realized while I had the pan off why not do the rear seal.

I have a few questions before I put it back together tomorrow.

1.) Haynes says to remove the bell housing inspection plate?

I took out all the bolts I could find (including 2 that go thru from
the rear) and it wouldn't budge. This didn't stop me from getting the
pan off so I can assume it was an unnessesary step.

2.) Haynes says to apply RTV to the chamfered edges of the bearing
retainer.

Looking at this picture .....do I have the right spot?

It seems to me if I apply RTV here it will play with the clearance
between the bearing and the cap.



3.) Also should I plan to appy rtv to the cork gaskets but should I
appy RTV to the rear oil pan seal when I reinstall?

Oh.... I almost forgot they also state in the manual to apply liquid
soap to the seal.... What would you folks recommend?

Thanks in advance.

Not necessary.

The factory manual recommends an anerobic sealer, Loctite 515.

Apply it only to the edges of the bearing cap, behind the lower seal half.
The factory manual recommends a 3mm tall bead of the 515 sealer.

If you over do it it may, that's why DC recommends the anerobic sealer.

Forget the old four-piece kit, get the new, grey one-piece pan gasket. Much
easier to install and will seal much better than the old style.

That works fine, however hi-temp grease works better.

The rear seal is a little deeper under the main bearing cap:

Re: Rear Seal / Oil Pan
 

If you follow the directions, you will get it.

I prefer the one piece pan gasket.

Then when you have it all back together and it still leaks out on the
ground, go up top and fix the leaky valve cover....
