gear noise Cub verse Super A

[49willard]

I recently purchased a Super A (1950). I have had my Cub for 44 years. The Cub gear noise is minimal compared to the Super A. Is this typical? Inspection of the square cut transmission gears looks and feels (for any slop) as you would expect, i.e. no worn looking gears or looseness like a bearing issue.

Depends on how many hours it has on it. I've seen Cubs that sounded awful and Super As that were very quiet, and vice versa.


As long as the lubricant is at the right level and you're not hearing clicks, pops, grinding, etc. I wouldn't worry too much.

Thanks for responding. I have no information on hours. The engine was replaced/rebuilt by the previous owner due to a crack in the block, front right and the compression is 135-140 psi. It sounds like some farmalls are gear noisy and some not. I do have the transmission topped with fluid and there are no other undesirable sounds.

I have a 130 and 2 x 140s and they all have different levels of trans noise as do my cubs. I am in the middle of a trans rebuild on one of the 140s. The pitch changed and the "slinger gear" which is made of a soft metal failed and was making bad noises. One of the bigger bearings was not right.

Hopefully, soon I will hear the difference between "normal" gear noise and a failing transmission

Greetings: I purchased a Super A last fall and drove it home, (about 10 miles) and the noise out of the rear was: very concerning. I checked the levels also and everything looked good. Still when I drive it around, the noise is there. I'm not capable or interested in tearing it apart. I have a Massey Ferguson 1533 as my main tractor, I bought the two together from the same guy, they keep each other company.

The 140 I did the trans rebuild is back together. Have smoother, quieter noises but are still different than my 140 and the cub. Noise is the nature of straight gears and IH trannies
