I recently discovered an oil leak underneath casing between engine and transmission. Thought it was the rear crankshaft seal or transmission shaft seal so split the tractor and replaced both seals. However, the leak is still there. It looks like it's hydraulic fluid. I then thought the steering orbitrol was leaking and hydraulic fluid was leaking into the flywheel casing between engine and transmission so I replaced the orbitrol but leak is still there. Don't know where it's coming from. Any ideas? I can send pictures of the exact location by mail.
