        I have a Jinma model 354 and the right brake unit keeps filling up with gear oil and leaks out where the linkage rod from the brake pedal enters the unit. The gear oil is leaking out of the transmission gear box.  I think there is a seal on a shaft that needs to be replaced.  Has anyone had this issue and what would be the best way to fix it?

         

        Thanks

          I have seen that a very few times.

          I have seen the seals( two, back to back) bad behind the brake assy.

          I have seen the allen head bolts weep oil due to improper torque.

          There is a O-ring under the collar the seal lip rides on weep/leak.

           

          You should be able to see the problem once dissassembled.

            I was looking at the schematics for the brake assembly and saw the seals, my first guess was bad seals, but it looks like a real job to take apart the  to replace the seal. If I ever some extra down time I start this project and contact you if I need the seals.

            Owning this tractor is like having another hobby as a mechanic. I enjoy fixing things  and this tractor is keeping me busy.
