1994 Kubota B20 Front of transmission seal leaking

[bsg9041]

Hello All,

I just bought a 1994 B20 and am having a pretty sizeable leak coming from the front of the transmission. Can I remove the driveshaft and just replace the seal? does anyone have a part # for this seal?

Yes
You will have to split the tractor in order to take out the propeller shaft to replace the seal.
And on a B20 that's quite the task.
You will need a good flat surface and jack stands and floor jack.
You split them at the clutch housing to motor section and I would also plan on changing the clutch disk, pressure plate, throw-out bearing, and pilot bushing all while your in there.

Clutch disk and pressure plate:

Thanks for the info! I was hoping to not have to tear it apart in order to replace that seal.
