Farmall Cub

I am in the process of redoing a 154 that has a lot of wear.The input shaftin the transmisson will move in and out about 1/8 of an inch. Are there some thrust washers inside that are wore or maybe thrust washer. I have not got into the transmission to see. Just wondering if any one on this board has any expericane in this area.

No experience with a 154, but since it is the same as a cub except for the length of the input shaft, 1/8 end play is normal. no thrust washers, etc. that I know of.
