Unknown. They came in sealed brown paper bags from Armyjeepparts with part numbers like those shown here on the bags typed out on white sticker labels. Bags looked like they had some age to them. I ordered the whole kit but the seals don't look the same as the first picture. They look more like the oversized seals they sell without the sleeves in the second picture.

As long as the open part of the seal with the spring retainer on it goes towards the oil then you are alright. In saying that you have to be sure with any seal that the spring stays on the seal after it is installed. A lot of times they will pop off during the installation and you have to finagle it back on. THAT is a tedious job! That is where those dental picks come in real handy. Nine times out of ten when I hear about a seal that started to leak very shortly after installation I will tell them to look for the mangled spring in there. At that point the seal needs to be replaced anyway. Once you put the yoke in if the spring had come of you are going to destroy it so always check before putting the yoke in.

Understood. I have yet to try putting in the yoke. I see how the seal works now. I don't have a socket that fits to hammer the sleeve down further so the dust seal will work as intended... maybe this weekend. Wife is currently on a new fridge kick and I'll be damned that I can't find a single one with the features she wants that fits the current space. Width is good then it's too deep, vice versa. Measurement #'s just not in my favor this week.

So, inquiring minds want to know, does the sleeve have to pressed on until it's seated???

I have been through tree new fridges in four years! They just do NOT last. And try collecting on the warranty! Yea, right. It takes an act of God to get that through. I had to get a letter from my lawyer to get Lowes to agree to replace my last one and when they delivered it they told me they were not responsible for taking the old one back, I would have to arrange for that! I loaded it in my pick up with my front end loader and took it to the store and then they told me they could not unload it because it was not on a skid!!! I called my lawyer and he suggested the "express unload" method. Yup, Unstrapped it and backed up like a bat out of hell and slammed on the brakes! UNLOADED! And drove off. My phone was ringing off the hook when I got home from them and I just told them to call my lawyer. Funny, I got 300.00 in gift certificates AND a written apology from the Lowes Vice president of operations. I buy very little from Lowes anymore. I used up the certificates and that was it. I will NEVER buy another major appliance from a big box store!

I always went just past the end of the yoke so I could file a smooth transition for the seal. I never put it all the way up to the end because the seal does not ride that far up.

Got it flush by using a method I read on here by sliding the yoke and sleeve onto the old transmission I had. To get it down further, I had a chance to go to the local hardware. Was going to go with a socket as suggested but ended up getting a black pipe nipple for a dollar. Worked out great. Added bonus I saw was that it hits the sleeve all the way around and not just the points of the socket. Only thing I would have done differently would have been to get a longer piece of pipe so I could hold it better. Filed the edge as suggested.

Hi all, I'm getting near to doing the seals on my transmission (seals and sleeve kit currently in my kitchen, and a large pool of EP90 on my garage floor is taunting me). Can the seals be renewed with the transmission in situ on the vehicle, or does the transmission have to come out to renew them?

Prior to my ownership I did help to install this transmission in this vehicle at a show, and it it didn't take us long (photographic evidence and vague memories suggests over 2x cans of beer) to get the motor and trans out and swapped, back in and and buttoned up. Having a Ward LaFrance M1A1 to hand probably helped, but we were also young and full of enthusiasm and determination. Unfortunately age has crept up on me, and keen-ness for undertaking large tasks seems to be wearing off...

Vince, the rear seal is very easy since the seal carrier comes off and the seal can be done on the bench but the front one is above the cross member. I have done them in the vehicle but getting the old seal out from that position will cause you to use every foul word you know plus you will learn or make up new ones. Can it be done? yes. will you want to do it? probably not. If you have a slide hammer type seal puller this makes the job easier and if you are fairly flexible and have a lift it is feasible that way, but still tight.

I think I'll go for pulling the whole power pack as that will give the opportunity to more easily clean all the oil from everything! The transmission we installed was sold as a reconditioned one, but I guess the seals have just age hardened as there is no scoring on the yokes.

Is it normal to have an amount of of up and down play in the yokes? Having studied the drawings, I can't see how the shafts can't have play given that they are just supported by roller bearings.

There should not be any significant play. That would result in a lot of vibration of the propeller shafts and the seals could not do their job.

Thanks, I thought that would be the case. At this rate, I may end up building 1 transfer case from the 2 that I have, as the one on the transmission which was removed seems to have less play in the shafts. I know that the gearbox itself had worn synchros which is why it was swapped out. I'll start tearing down the one on the bench, as perhaps that would be the better beneficiary for the replacement seals.
