Yoke Wear Sleeves

Unread post by Surveyor » October 4th, 2016, 9:10 pm

I am to the point of changing out seals and placing on the wear sleeves for the replacement transmission I got awhile back. First seal went in just fine in the easy one on the bottom rear. These new seals look cheap compared to the original with one versus two lips but I could tell by the grooves in the yokes that they needed to be changed. Was able to get the first wear sleeve onto the yoke but the face of it is now flush with the end and I need to go probably another 1/4" to bottom out. If I don't it looks like the seal will be too far back and over the old shaft and not over the new sleeve. Recommended way for this backyard mechanic to get it the rest of the way down?

There are three that came in the kit. Two long ones for the yokes and the third short one for the brake. This is one of the "long" ones.

Have a set of sleeves from a 79 contract in front of me.
The long one is pn 11669169-1 and the shorter is -3.
Length for long about 1". Short anbout 3/4 "
The seals are indeed two lip pn 11669194-1

Hope this helps.

I use a large socket that will just fit over the yoke but the teeth of the socket will catch the sleeve and push it further down the yoke. Then I take a fine file and dress the end so it is a smooth transition for the seal to go over the end. I finish it off with medium emory cloth, just the edge, not the face of the sleeve.

I have a 3/4 inch drive 12 point 1-1/4 socket that fits over the yoke just right but, my 1/2 inch drive 1-1/4 fits a little tight so check your sockets to see what fits best.

Will do. Thanks for the recommendations. Thought about that at first but I needed expert opinions to belay my nerves on screwing something up.

Kind of confusing.
Every time I have put on wear sleeves I drove them on with an oak block .
They seated and that was it.
No filing on sanding.
Have had more problems with sliding the yoke on to the shaft without distorting things.

I think rick means he files and sands after seating the sleeve so that the yoke goes in easier. Just measured it and it won't seal without pushing it down further. :cry: Only thing I can think of is that I put the seal in backwards (one lip)????. That's the only one I've done so far and the lip protrudes out toward the drive shaft. Look correct?

The seal looks different from mine.
The outer lip seems closer to the outside than what you show.
The rolled edge should be facing outward.
The seal face is approx 1/16-1/8 recessed. The rear is approx 3/16 recessed. There are two lips.
The inner one has a fine spring around its circumfance
Hope that helps.

That seal is in correctly, what you are looking at right there is the dist lip and the oil seal will be inside and should have a spring around the inside lip of it. The version Fill is talking about is the original military seal that had two heavy sealing lips and no dust seal.

Ahhh.... there is the confusion. I was thinking the dust seal was the oil seal. I'll have to check the backside of the other two... don't remember seeing a spring. That said, I still think I need to drive it down further or the dust seal won't be doing much of anything. Thanks for the input all. So far with all the info here and in ya'll heads my knock on wood moments have been minimal.

Were your seals military NOS or civy equivalent?
If they were civy then that could be the difference.

I knew I had seen this before, this was on one of Frederic's rebuild.
