Transmission input seal

From TM

I did one like Boss Hog said but I never glued my seal in the retainer. It stayed in place. I got my seal from NAPA.

Sometimes I guess i do a little overkill But I do a lot for other people , no comebacks
I also use NAPA seals

I've done two seals in my cub time, Merlin and Roland. One was tight as tight could be and one was loose. Both had seals from NAPA. Wonder if there were different seal retainers used?

The parts book does not distinguish between the seal and retainer, it is all listed as one assembly, and I only see one version, not multiples offered throughout the years.

The seal is after market

Brian I have seen two different types of seals and retainers. One like the pic above, and another that had a protrusion on both sides that when first seen will give you the impression that the retainer is installed backwards. The seals that I've seen in this version appear to be leather.

Raymond, thanks for the info, it seems like leather seals would have been on earlier tractors and then the manufacturer went to rubber in later years? I'm not sure, I have only come across the one style pictured.

The seal on mine has the protrusion from both sides. It really-really looks like one piece.

I've got a new seal/retainer coming in the mail, hopefully today.

There was at least one part number change on that seal. The early parts catalogs call out 350 865 R91. The latest call out 528 810 R91. Interetingly enough, the early says the 3 retaining cap screws are 3/4 long. The late calls out cap screws that are 11/16 long. The hardware difference is consistent with 2 vs. 1 layer of sheet metal stamping for the retainer.

Jim, why does Rev F not call out two individual part numbers, similar for example like the steering knuckle, I guess it was just an IH thing probably?

Jim, why does Rev F not call out two individual part numbers . . . ?

Because the newer part can be substitutesd for the earlier one. There was no reason to maintain a supply of the earlier part.

Fewer than half of the parts included in TC-37F were in the originl TC-37. Many of them are for equipment that was added, but it still represents a lot of substitutions over the years. There is no point cluttering a current catalog with obsolete parts.

Mine has National 350865R91 stamped on the seal. Google comes up blank when I checked.

The new seal was sitting on the porch when I got home.

Got it in, and got the tractor buttoned back up.

Let me run this installation technique by you:

1. I wrapped an old Tractor Supply receipt around the input shaft, then slid the seal on to the paper.
2. I then carefully slid the paper down the shaft with the seal on it.
3. Once I got on to the smooth shaft at the transmission, I peeled the paper out from under the seal and slid it into place.
