NH L785 Hyd Pump Leak

robbp · Jan 25, 2009

There is a hyd leak from around the shaft on the back pump which operates the left drive side of the skidsteer. It only leaks when the forward/reverse control is engaged to move or steer the machine. The schematic only shows one seal on the shaft at the back where the leak is coming from, which sits behind a snap ring. The service manual only gives a procedure that explains to press the shaft out upon disassembly in a press. Does anyone know if you have to remove the shaft to get this seal out or can the seal just be replaced by removing the snap ring? It appears the whole pump unit (which is 3 pumps all in one unit) has to be removed from the machine to get access to this pump.

thanks,
Rob

You may want to pull the pumps and have them checked. Usually if the seal is leaking that means the pump is leaking internally and is bypassing more oil than the case drain can carry away.
