Hey guys, Having an issue with my 310G backhoe. There is hydraulic fluid getting into my rear end, which is filling up and coming out the breather vent. I replaced the three seals on the emergency brake housing, but its still acting up. After replacing the seals, I put fresh fluid in the rear end, used it for awhile and I'm assuming it filled back up because it is doing the same thing. A side note, it was sitting for two weeks and didn't start leaking until the past couple of days. Any advice would be appreciated thanks.
Welcome to hef burkhard1990 ! When you differential fills, is the hydraulic oil going down or is the transmission oil dropping?
Hydraulic oil level is dropping.
Hydraulic oil would be the brake seals. Transmission oil would be the park brake or diff lock.
That’s what I was afraid of, really not looking forward to that job.
