Please help!! Ford 800 rear main

[Bandit7]

I’m trying to help my dad, he’s had My papaws 1963 ford 800 gas tractor apart 4-5 times and can’t keep it from leaking oil out of the rear main, He’s tried the rubber and rope seal he’s tried taking one out he’s tried silicone on the side holes and everything. Every time it starts back leaking bad. I feel bad for him as this was his dad’s tractor and he keeps trying and trying but nothing is fixing it. Any help is very much appreciated!! Local Ford dealer doesn’t know

Is the crank rough? If it is, you'll need a Speedi-Sleeve.

Could be the problem! I’ll have to try to find one on here. Is he supposed to use both seals or only one?

I will show him this again. He tried this the last time and it still leaked, Hopefully he can figure it out one guy recommended maybe a Speedi-sleeve I’ve looked on here and can’t find one I’ll keep looking! Thanks

The rear main bearing cap has two grooves next to the babbit bearing. The outer groove is the seal groove, the inner groove is an oil lubrication groove and lubricates the babbit bearing, nothing goes in the inner groove.

Hey lost wrench m, He only used the seal in the outer groove the last time and it’s still leaking

I speedy sleeve will not work as the rear crank flange is much bigger than the seal surface.
I have not had trouble with the rubber type the lip goes toward the front and I shove a little ultra gray in the side grooves before I install the wedge seals and pins.

My wedge seals was just a hard like rubber that goes up in there but there where no pins?

 

[cushman]

I do not mean the lip goes in the front groove,if that is the way it sounds.

I know what you meant, can you send me a link to the wedge seals you use?

Yes,not all wedges have the pins,thet last one i did had them.But I found the main bearing cap will leak between it and the block without pushing some sealant in before shoving the wedges in.

he tried that the last time the sealant was called “the right stuff” I think? Local machine shop recommended it but I will tell him to try ultra grey. How much do you use on each seal?

Another guy replied and said a speedy sleeve will not work as the rear crank flange is much bigger than the seal surface.

You are not alone!! There are plenty of threads here about problems with these seals. I have done a few and there are too many ways to go wrong to try to steer you right when we can't even figure out how you were doing it. I, like lost wrench did catch that he tried putting a seal in each groove. I suggest you view the You tube video by Chicken House Mechanic.

The crazy part is when he pulled it apart the first time it had a rope seal in front groove and rubber seal in rear, Maybe not from the factory but it never leaked before the rehaul, it’s been a struggle hopefully he can get it right this go around we are gonna try the same deal that chicken house uses

I just put one in a FE block I did not use the rubber side seals YUK!!! I used the old paper wedge seals : ) they were in great shape and stuck well the the cap. I am cleaning up and what do I do with the rubber side seals. I went to youtube and googled FE rear main seal. First one "WHUTS THIS" its interesting BTW I liked the way he sealed the cap to block wink wink...

Is he soaking the seals for a couple hours before installation? A dry rope seals may overheat and glaze before the oil gets to it. ( if he is indeed using a rope).

I prefer a rope on an iffy crank because a lip seal needs a little more accuracy.

Thank you. Hoping he can figure this out! He don’t have the money to buy another tractor and I can see it’s really bothered him. I think he’s going to try the bs 6141-3 seal kit that was in the video and use the victor reinz rtv for the sides and not use the pencil type seals?
