clark Ranger 664C leaking fluid
« on: July 29, 2020, 12:00:42 PM »
Hello everyone , this is my first post. I have a Clark Ranger 664C and it started pushing transmission fluid out  around the breather on the torque. Does any one have any thoughts what would cause this to happen.

Does your 664c have a divorced converter?  If so there is a drain hose from the converter to transmission housing that could be kinked or blocked. Also transmission pump could be leaking through the shaft seal making the volume to great to drain as it would normally .

Thanks  Kiko I'll check on the return line. I just rebuilt the torque and put a new charge pump on the old girl . It was leaking a little bit before but now it's leaking worse. half a gallon every couple of days.

The seal ring set under the stator would be another source of internal converter leakage. Some of the Clark convertors that stator seal was a two piece seal that had a spring of sorts under the seal to keep it expanded.
