MC70B leaking hydraulic fluid into be=gear box

[retiredusaf]

My left side drive box is over serviced and started leaking threw the parking brake cog into the hydraulic bay of my skid steer. Is this a sign that my drive motor needs to be resealed? If so, is it the front side or back side of the motor? I have done several hours of research and can't come up with much on resealing the drive motor. Any help would be greatly appreciated.

Depending on the style of drive motor, some have seals on the high pressure side, but the low pressure/case drain is open. There should be a seal to stop fluid passing from the open side of the drive motor to inside teh gear box. Bobcat have this setup at least, if the case drain filters have a restriction, pressure can build and push past the seal.
Hopefully your issue is this simple, just a bad seal to the gear box.
Hopefully someone that has one of these can assist more.
