B9200 HST Fluid Leak at RH brake lever shaft.

[KTOY]

I have a leak at the shaft where it goes into the brake housing. My service manual is useless because it just explains how the brakes work with minimal diagrams and no repair instructions. Parts diagrams show no seal here. Are these dry brake shoes, if so, why is there oil? I'm at a loss, advice would be greatly appreciated. I like to know what to expect before I start to take things apart.

Thanks in advance..

I did this repair on my neighbors tractor two years ago. It was fairly straight forward with respect to removing the brake housing with the lever going through it.

An o-ring is used to seal the housing and shaft. For some reason I'm thinking there may have been two o-rings used per side. Can't remember the size off hand.

Other than oil leaking from the housing it was a straight forward repair.

It very likely you'll need a new housing gasket. You might want to purchase before starting the job.

Good luck.

They are wet brakes (sort of), the seals are 2 simple O rings.

If you pull the cover you'll need to get the gasket for the cover too.

Thank you gentlemen, I knew I came to the right place. Should there even be oil in there? Inner seal?

Nope just the 2 O-rings (put on on the inside of the shaft), the rest is open to exchange fluid as needed.
