Rear main seal
Can you replace the rear main seal on a 91 4.0 YJ automatic without removing
the engine? If so, what is involved. -- ----------------------------------------------------- Click here for Free Video!! http://www.gohip.com/free_video/ |
Re: Rear main seal
Yes. You must drain the oil & remove the oil pan, then remove the rear main
bearing cap & bearing. You then GENTLY push out the old upper seal half and reinstall a replacement. Remove the old lower seal half at the rear of the rear main bearing cap, install the new lower seal half , torque the main bearing cap in several steps to the factory torque, reinstall the pan with a new gasket, torque all pan bolts evenly and you're done.....But wait, there's more! What leaks as often as the seal is the pan gasket at the rear main bearing cap. When you reinstall a new pan gasket get the one piece unit sold by the dealer (it's gray rubber.), put a good RTV bead on the groove in the rear main seal where the pan gasket seats, plus put some on the pan surface all along the rear of the pan, opposite the rear main bearing cap. Be sure to install the gasket FIRST, holding it in place with a few studs in the oil pan bolt holes (these keep it in place while you install the pan. If you do all this, and if you didn't FU the new seal putting it in, the fix will last about 25k - 40k miles before it starts to leak again.

Re: Rear main seal
Either you're a real optimist or the luckiest guy around, unless
your'e definition of GENTLY is a whole lot different than mine! Mine took a brass drift and a 4 pound hammer on top of lots of cussing to break that top half-seal loose! Of course this was an '88 but a '91 has had time to cook in, too. Just be sure you get a brass drift punch - welding rod or a stick of brass from the hardware store just a little under a quarter inch will do - so you don't bugger the crank surface. It also helps to loosen the main bearing caps a bit but be sure you support the tranny on a jack to keep stress off the crank. You need to use a small amount of silicone sealer on the rear bearing cap ends of the seals so that they mate right - see the shop manual and I think even the Haynes manual mentions this. Besides getting the pan off (it grows on, too) you will need to pull the starter for working clearance. The first time I had the pan off I spent a lot more time getting the old gasket scraped off than the rest of the job combined, including the time it took to finally bang the upper half of the seal out. A little research will also make the job of getting the pan seal back in place a lot easier. I personally use a thin layer of silicone both to help the seal as well as to tack it up on the block while I lift the pan. Just be careful as you put the bolts in - the silicone makes the gasket slip around pretty easily, so get all the bolts started before you start to tighten any of them. Replacing the seal is actually the easiest part of the process. On Mon, 22 Sep 2003 00:54:51 UTC "Gerald G. McGeorge" <gmcgeorge@frontier.net> wrote: > Yes.

Re: Rear main seal
Yes.
You simply remove the oil pan, loosen the bearing caps, and remove the rear bearing cap. That said, you have a leaking valve cover gasket, not a leaking rear main seal. <rorr4@cfl.rr.com> wrote in message news:1lrbb.18767$Qd.704863@twister.tampabay.rr.com ... > Can you replace the rear main seal on a 91 4.0 YJ automatic without removing > the engine?

Most of the time the upper seal half comes right out, UNLESS some moron decided to use sealer on it, which may have been what caused Will's to be so stubborn.

This isn't necessary on later ones with the little Chrysler starter. It is on CJs', etc. with the larger Ford-type unit. The factory YJ manual suggests making 1" studs to insert into the larger pan bolt holes on either side of the block. They suggests taking 1" long bolts, grinding the heads off of then and cutting slots in the ends. (Whew, lot of work!) You put the studs into the bolt holes on either side the block and slip the seal over the studs before installing the pan. They hold it in place while you muscle the pan back on. Not wanting this much work I simply went to the local hardware store & found some some threaded studs with slots in the ends and used them. Worked like a charm. One last thought, be careful not to over tighten the small front-most pan bolts. They are very short and seat in the aluminum front cover. If you strip them out you'll have to pull the damper and replace the fron cover, which won't be fun.. > On Mon, 22 Sep 2003 00:54:51 UTC "Gerald G.

Re: Rear main seal
What? Maybe in a lexus, but in a Jeep you just pull the bearing cap.

Re: Rear main seal
You're talking about the pan gasket, not the seal.

Re: Rear main seal
Wrongo. The lower half of the seal has tabs on either end that fit in
grooves in the bearing cap. This is what differentiates the top half from the lower. If you use the factory pan gasket it's one piece. The older, 4 piece (POS) pan gasket has tabs for the front & rear pieces. I'd run from that version like it had herpes! "L.W.

Re: Rear main seal
That four piece pan gasket bites the big one. It is the hardest thing to get
on right I have done in a while. I wish I knew about the one piece when I did mine. Holy crap between removing the stock gasket and installing the four piece It was one heck of a miserable job.

Re: Rear main seal
Hi Kevin,
I've been getting away with just laying line of silicone about 3/16 of an inch around over a perfectly clean surfaces, right down the center jogging to the inside around pan bolts, that amount doesn't slop out.
