I am working on a caterpillar 215c lc excavator and i have oil coming out of the breather on final drive past drive motor. Does anyone have a breakdown on this ?
We might - with a Serial Number........ There are a dozen different models of 215.
Serial # 4HG00971
You mean this breather (relief fitting) #16 in the parking brake housing..? My first thought would be a parking brake piston seal leaking, second would be a travel motor shaft seal. Either way it would take disassembly to find out.
