I have a mysterious hydrostatic leak on a 963B track loader. The oil level in the transmission drops when it is operated and the only evidence of external oil leak I can find is coming out of frame weldment all the way up by the forward cab pivot (behind the lift arm pivot pin) The machine has consumed about 15 gallons of oil in 1 hr of operation. Transmission divider box is slightly overfilled but the oil definitely did not all go there. My only thought is it is the left hydraulic brake circuit or left track drive motor shaft seal is leaking into the cavity between the final drive and track motor and I have filled the entire machine frame with oil. Not looking forward to pulling either the final drive or track motor but was wondering if there is any test to perform to ascertain which component is leaking and if I should pull the track motor or the final drive. Neither of which looks like a particularly fun project. As long as the oil in the transmission is maintained at the proper level the machine operates normally.
Thanks for any advice.
