Loosing hydraulic oil.

[Rookie]

Loosing hydraulic oil, but where? I've gone through almost two gallons in about eight hours. I have one tilt cylinder that's a little damp but not actually leaking. No tracks on the ground, even when sitting idle. My worst fear is a motor seal is blown and it's filling one of the chain cases (haven't checked that yet, 'fraid to). Suggestions?

Yesterday I drained one gallon of excess oil from the right chain case and over five gallons from the right. It appears that the motor seals have blown. What could have caused this? There is good access to the motor fronts through the chain case covers. Can the motors be re-sealed without removing them?

Update: Not loosing oil anymore - fixed itself.

I know, an old thread but 'Fixed itself' always leaves me with the hair on the back of my head standing on end!

I forgot all about this thread (I had to re-join due to lost info). Yeah, it was the parking brake cylinders. Replaced one two years ago and recently the other one let go. Parts on order. These cylinders are difficult to find in spite of being used in a wide variety of equipment.
