TR4/4A Transmission counter shaft end float.

[John_Progess]

The manual says there should be .006" to .010" end float for the counter shaft gear. I mentioned in an earlier post that I had a terrible time getting the counter shaft gear out of the box because the rear bearing fouled the thrust washer and jammed the gear in the case. I have installed new counter shaft bearings and new thrust washers but now I only have about .001" end float clearance if any at all. With the counter shaft and thrust washers installed in the case it actually feels like it is dragging slightly as I spin the counter shaft gear. Moss only lists one choice for each of the thrust washers so do I need to dress down the bosses in the case to get my .006" float or what have other people done to solve this problem? Thanks for your help and have a good day!

I believe it would be better to take material off the thrust washer, but others may have a different opinion, I have reduced the thickness of a thrust washer in the past by taping a piece of emery cloth onto a piece of glass on top of a flat surface and carefully moved the washer back and forth and around and around to grind down the thickness of the washer. I believe some people use a belt sander but I don't have one. It can be a slow process doing it by hand but it works.

Bob,
My only concern with reducing the thrust washer thickness is that you have to reduce the thickness on the brass/wear side as the other side has the notch on it. Is there any concern that reducing the brass side will cause a problem? I know I am only talking about removing .003" from each washer. Thanks for your help and have a good day?

If you have a friend with a lathe, a small of material can be faced off the distance piece (Moss 848-630) to increase the end float . Usually, the problem is excess end float, in which case, shim stock can be placed behind the thrust washers or distance piece.
