1953 transmission growl

Postby 1953vacub » Tue Sep 28, 2021 10:27 pm

My cub had a worn out trans when I baught it. I have since completely rebuilt the trans and finals all new bearings and seals. Put everything back together and first and reverse growl loud. I baught a cub cadet trans for parts and switched out the main gears and sliders still growl. Iv tried both sets together and iv also mixed the sets every combo iv tried same growl. Is it possible iv got two trans with same wore out parts or am I missing something? Second and third gears work perfect and quiet and I'm running 80w90 gear oil. Any advice would be appreciated

These things have loud transmissions. Not saying yours may not be louder than normal though. Have you been around another one and heard how it sounds? I have heard it's the way the gears are cut or something? Just saying these things have all kinds of hydraulic noise and transmission noise. My late 70s Yanmar doesn't have any of these noises, it is had to hear over the Loud clack clack of the 2 cylinder diesel.

They have straight cut gears which have a tendency to growl.
I have an excuse. CRS.

I have heard before that they are noisy gears but i have not been around another cub to compare it to. what I was goin on was how much quieter 2nd and 3rd gears are they should be the same type of gears so I was hoping to get close to their sound. I think I'm going to try a new slider gear. will it mesh with old gears or do both need to be replaced?

Some are just louder than others and 1st and reverse are always the loudest. 3rd gear is 1:1 ratio, so that’s the quietest running combination, reduction for 2nd, more reduction for 1st and reverse, just naturally more noise. It seems that everyone who has tried to quiet them down have met with limited success. If you know you have good bearings are your gears are all in excellent condition, you might consider buttoning it up and accept that yours is not one of the quiet ones. I wonder if it might be a tolerance issue on the machining of the transmission case that causes some to be quieter than others (just guessing)
I’m in the process of doing transmission repair, on Cubota. It’s been getting progressively louder and I was expecting to find bearing issues. Actually, the gears look terrible, wouldn’t take too much more abuse from the little diesel to start breaking gears. I too, bought a cadet trans but I’m using it case and all. Just a few changes and it’s a proper Cub transmission. I don’t lose factory ring and pinion set-up, that way. The replacement is ready to go but I’m being a bit lazy about ripping the tractor apart.

I have several cubs they all growl. None sound the same. Took a couple of years to get use to it. And I still worry about it.

By the way, I'm just across the hill from you.

Yea the noise as these things move and run bothered me the first times I ran mine. After watching hours of them on YouTube and hearing the few I have in real life. I have come to realize they are loud machines. Nothing like modern or even tractors from the 80s.

What weight oil are you using in the trans?

Not that it makes a big difference but I have tried using heavier gear oil in a few of the louder ones and maybe overfilling slightly
When you only have 9 horsepower you need to know the names of all of the ponies!

I use to visit Green Valley every year prior to Christmas. My daughter loved books when she was younger. Not so much now life gets busier as one gets older.

If you can get a video up that would help everyone to help reassure you nothing to worry about or what to look at for a problem. Lots of good help here.
