Transfer installation question

I am installing my d-18 and have a couple questions. Should there be a gasket between the transfer and tranny? I have heard that alot of times you do not need a gasket between machined surfaces and I wasnt sure if this applies here. Also, I am missing a bolt that holds the transfer and tranny together and wondered if anyone knows off the top of there head the size of bolt that is.

 

You definitly need a gasket. Half the time it leaks even with one

 

ya need a gasket, and I think It's a 3/8 x 16 bolt.

 

If you have the means to get the tranny/xfer apart enough to really clean up the mating surfaces, I've had great luck with the gasket installed with Permatex Aviation Sealer (#2 IIRC. It's the molasses lookin' stuff.)
But as with any sealer, the surfaces need to be C L E A N.

At any rate, I'd go with the gasket for sure.

You may want TO BE CERTAIN that the idiot mechanic didn't put the locking plate on the T90 in such a way that keeps the tranny mating to the xfer perfectly. If the two don't go together all the way without brute force, I'd double check.
Read this page for further info on that particular problem. About 3/4 the way down, red lettering.

 

It's a t-14 thats in it now. Would that still apply in this case.

 

That is a good question. Anyone?

 

There is a bearing retainer in there and its probably cocked to one side which is causing the cases to not go together heck he could even have it in backwards. Seperate the 2 cases completely and clean up the surface and make sure the reatainer is put in right and then put the gasket and the Permatex sealer back on and reassemble.
When you're all done with this go beat the sh#$ out of the idiot mechanic that screwed you over.

Good Luck and hope this helps!!!!!!!!!!!!!!!!!!

 

Alright, I got it out last night and part of the problem I'm sure was that one, 2 or 3 or the bolts were barely more than finger tight, the bearing retainer was cocked because he had a huge glob of rtv behind it, and he didnt use any type of gasket he just globbed a bunch rtv all over it.

I have a couple questions just to double check, the bearing retainer should have the tapered edge facing out right? My main drive gear is chewed up a little, no missing teeth or no huge chunks are out of it but its just rough. the gear on the transfer is in perfect condition. There is no way I would have the money to get a new gear rigth now and I need to get my Jeep on the road quick so I can get to work and give my borrowed ride back. Do any of you think that it would be a horrible idea to drive it like this. I know its not optimal and I will replace when I get the chance but like I said I need to get on the road quick. Thanks.

 

Finally got the transfer in last night. Doing it solo with nothing but a floor jack on gravel was quite a task to say the least haha. While I was under there I used Bills clutch linkage method with the Heim joints and the clutch is working great now. Excellent upgrade for under twenty bucks.
