final drive

Hi i have a 48 cub that is in pretty good shape but the rear end is extremely noisy. Is there any adjustment in the gears that drive the rear wheels or is this a major problem. Thanks Dave

David. Welcome to the board and don't forget to read the Announcement and Sticky at the top of the Farmall Cub index posts. Plenty of excellent info there...........

there can be a number of causes for your noise that would require dismantling the rear of the tractor. but before you do that, change the fluid in the transmission and final drives using #90weight and see if that quiets it enough. you can go a little deeper by removing the shifter cover it's a simple way to look at the transmission. just remove the 10 or so screws in the cover and lift off. that will tell you whats up... ie rust, water, gunk, look especially at the oil gallery for the top shaft rear bearing.
if you have water in the transmission, a fill with kerosene or diesel and run it around will clean it up. then refill with #90 gear lube.

hope this helps, :!: otherwise, time to get greasy :) 8)

Hi Dave :lol:
8) Glad to see you here. From my point of view I would change all the fluids. It is an cheap investment. The trans just seems to draw water. The 1st-reverse shifting fork in mine was broken when I got it because someone tried to move it when there was ice in the trans. I would change the fluids and see how it sounds. If you don't use it in winter you can use the heaver 140# gear oil.

Good luck :P
