Happy New year ,
I have a 1952 m38
can I change the pinon seal without changing the crush sleeve?
thank you in advance


Hello Tim, I have relocated your post that asks a technical question from our Member's project board to our "Technical Questions" board.

I could be wrong but I don't think there is a crush seal. Just remove yoke and replace seal, replace yoke after checking seal contact area for wear.

Make sure to check the yoke for any seal wear. If so use speedy sleeve #99155
Use indian Shellac when installing it...Also shellac around outside edge of new seal and a coat on yoke splines.

Leak proof it will be

Here's a comparison of original style vs newer style seals.



Usually a leakage problem right after installing either of these seals will be caused by one of the following:

1 - Damaged seal lip during installation.
2 - Worn and/or grooved sealing surface on the yoke. (This can be addressed with a new "Speedie Sleeve" on your grooved yoke)
3 - Excessively worn and/or loose components.

Steps you should take to insure a leak free new seal installation are:

1 - Follow all directions carefully.
2 - Apply sealant carefully and sparingly only where the instructions tell you to.
3 - Apply grease to the yoke splines and the pinion spline.
4 - Insure the open edge of the seal lip that fits shaft tightest faces the gear oil source.
5 - Lubricate the seal lip before installation.
