Input shaft seal, how do I get to it?

Is "the right stuff" anaerobic? I have had good luck with this stuff elsewhere on my truck.

I usually use black RTV for the trans to t-case area. You can use a gasket too... doesn't matter. "The Right Stuff" will work fine.

anerobic sealant for the plate. it does not need air to cure.
do not use a gasket on the front plate.

I will just make a recommendation on my experiences with the no gasket on the front plate. Your results may differ. The gasket was included when transmission was assembled to get proper endplay specs. The other gaskets are not as critical. Silicone would be my choice if just enough is applied (more is not better) over anaerobic sealing. Sealing surfaces that take anaerobic type sealing have both surfaces finished for this type of seal. Again just my 2 cents certainly not the only way to do this repair.

thanks for the info. I edited my posts.

So you suggestion is to track down a gasket then?

Whoever was in my fm146, for whatever reason, used some sort of rtf.

Also, if I did go gasket, would I use some sort of sealant or gasket conditioner as well or install dry?

Wish I had a transmission manual...torque values would be nice.

I don't think you quite got the scope of his message there sir

guess not, what am i missing here? just trying t figure the best way to do this

I think he basically made two statements there EC, the second one beginning with the word "Silicone"

Here are the specs on torque. Lb/ft. I was stating simply what has served me well over the years but that is me. If you choose to use gasket use high tac or shellac before install.

I'm no real expert with these type sealers either, just looked it up
Anaerobic means "living, active, occurring, or existing in the absence of free oxygen", as opposed to aerobic which means "living, active, or occurring only in the presence of oxygen."

One cures without any present oxygen, the other requires it I suppose

I may have messed up in replacing my intake because I wasn't aware of its' curing characteristics

What did you use on the intake?

 

[Josh B]

Not sure Transman, I wondered earlier if I'd still be able to find it. It came with a two piece lower intake gasket and was there to use on the front and rear ridges across the block. A black stuff in a red tube iirc
I didn't realize it would cure so fast due to other types being slow so took my time getting to the final torque, 10-15 minutes. It could have cured out before I finalized torquing the bolts so I'll be watching for oil leaks and possibly re-doing it

Thanks a ton for this information!

For better or worse I am going with a gasket. Just ordered a set. I'll update the thread as I move forward.

Well, I finally got it back together. Really there is no rocket science to reassembly. Put the seal in the bearing cover, use some grease to place the spacer ring in the slot on the cover and put it back together. I do have one worry with my specific installation though. I had some trouble getting the studs that hold the bell housing on tight when I installed them. I used two nuts, but could not get them to jam in order to tighten the stud. Eventually I used two wrenches and two nuts. I applied some pressure to the left with the inward on while tightening to the right with the other. I was able to get each one about a half a turn past hand tight. After that I put the bell housing on and when I put the nuts on those studs I tightened the snot out of them hoping that it would screw them into the tansmission housing even more. It looks tight, but I really don't want to drop the tranny again anytime soon. I am wondering if I should do it over so I can get those tighter, or do you guys think it will be fine?
