Whine in transmission

[SundaySailor]

Hi folks.

One of the things I didn't do when I was doing a restoration on my Farmall Cub (1950) was to tear into the transmission. Main reason: money, and it did work. It just whined. Mostly in first gear. Second and third seem to be relatively quiet.

With that in mind, what do you think I would need to do to quieten down my transmission? 1st & 3rd slider gear? Or what?

What are my options? TMTractor used to sell the individual gears, but I think that has gone by the wayside now.

As always, thanks in advance for your help.

Cheers!

Find a Cub Cadet gearbox in good condition and swap the gear set into your transmission case (if you want to keep the original casting number). CCs were used for mowing an hour a week and most had shelter in a suburban garage. Contrast that to a Cub being hammered 10-12 hours a day cultivating. Best thing i ever did to my gearboxes.

It is funny how the grinds/whines are different in different transmissions. On Lewis, his tranny needs to be completely torn down and reworked...it is awful, but strangely enough 2nd gear is relatively quiet...not perfectly quiet, but relatively. 1st, reverse and third are just awful. It will be interesting to find out why 2nd is so quiet compared with its brothers and sisters...

I like to look at these folks as they make some cool parts. Many of them are not helpful but the front pinion holder looks good to me. The original is a little cheesy. Like those forks, too. . Looks like it is easy to sink a lot of cash into a CC pulling tractor

You learn something new every day...amazing that there is that much market out there for tranny parts.
Since the driven speed gears are 2-3X the drive speed gears, you're probably best to put new sliders in. Some put both in new, but on the cheap, a pair of sliders are less than $100 and you can get new....

When I take the Wine out of the tranny, I like to put hytran back in.

The Wine tastes better before you put it in your tranny by the way.

Thanks folks for the replies.

I managed to snag what appears to be a decent set of Cub Cadet 122 gears, and I also found the 2nd-3rd slider and the first and reverse slider gears BRAND NEW. All of them came from that place none of us like, but need to use from time to time.

I know I spent more than I anticipated, but I want my transmission to be nice and quiet again. This should just about do the trick. I have my splitting stands and I know how to split the tractor and get it back together, so I'm putting this chore on my next year's schedule in the fall.

I'm surprised that nobody has really invoked the "standard answer" for the whine in a Cub transmission...

I.E., a Cub transmission is gonna whine to some degree no matter what. Straight-cut gears being what they are. You may go through all that rigamarole of changing out gears only to find out that it whines just as much, if not more, with all new parts.

Between me and Dad we've got experience with four Cubs, a '52, a '53, a '66 Loboy and a '67. They all whine to about the same degree in 1st, are pretty quiet in 2nd, and whine in 3rd.

Matt,

I was aware of the square cut gears - especially since the Cub's transmission isn't a synchronized transmission.

Back in 2010, I restored a 1200 model Cub Cadet. It had a straight drive transmission just like my Farmall Cub. Once I took it out for a drive several times, that's when I noticed my Farmall Cub's transmission had a very loud whine in first gear. That 1200 Cub Cadet had one of the quietest transmissions I'd ever heard. I almost wanted to use it back then in my Cub and vice versa.

I do know my Farmall Cub lead a hard life. That's probably why it sounds like it does. The prior owners didn't think much of taking care of this tractor. After all, it is a tractor isn't it?

Anyway, thanks for chiming in. I may have missed something if I hadn't asked.

Cheers folks.
