Help with JD90 skid steer drive motor.

I have a JD90 skid steer. Works well, but lately one of the hydrostat drive motors is leaking pretty bad. When parked over the winter it will drain the hydro tank. Driving I get a steady drip. The manual has pretty poor information on removing the motor. Any ideas on removal/ repair?

I am guessing at removing the skid plate, hydraulic lines. Then will it slide out of the gear/bearing? It looks like a bolt that holds it in place from the outside? Or do I need to loosen tension and take drive chains off?

On the motor view it shows 2 large O rings. (#12) I am guessing that is the only place where the fluid could be leaking from? The hoses look good. It is dripping off the motor case.

I think it uses the non pressurized hose as the return?
 
I have never been into a John Deere skid loader maybe nobody else has either ? Shady seals o rings and fitting and hoses are place that can leak
