Transmission Flush
 

I was wondering how you guys flush out your trannys. On early model Cub Cadets.
Thanks

take the back plate off wash it out and if it real bad inside I take the trans out of tractor and take axel tubes of and wash it all. I also if it has a bottom plug and drained it then put kerosene in and drove around shop and drain it out until it looks clean. but that's for gear drive only DO NOT do this with a hydro it will mess the pump up

It kinda depends on the model and how crudded up it is.

On an Original, you can take the plug out of the bottom of the transmission housing to drain the fluid, then remove the gear shift and/or the rear cover to gain access to the inside. I normally use diesel fuel in a pump up garden sprayer to wash them out.

Originals have a seal in the differential bearing retainers that the later models don't have. Over time these seals will leak and the axle housing can fill up with oil and water and there is nowhere for it to drain (except out the end of the axle housing).

That said, if your Original has spent much time setting outside, you may want to remove the axle tubes to clean them out and replace the seals while you're there.

I see a hole at the bottom. Is this a drain hole?

There is a plug under the neath.

My drain hole is leaking. When I drained the trans and filled it back up. The hole drips. Then I wait a day and no more dripping. Do I have seals going bad?

The drain plug underneath leaks?

How much does it leak before it stops?

From here, I can't tell if you have any bad seals.

The hole your talking about is on the brake linkage side?
If so the seals are bad.

There is a small hole at the bottom of the axle housing where you connect your wheels. . You know, where the axel goes through. It's not a plug it's a hole. Im hoping I'm making more sense. Maybe I'll upload a picture so you can see what I'm talking about

Yes, it's on the brake side. Is the seals a cub cadet thing or can I get them at napa?
