Hi Everyone -
Got a 988 with Front end loader, 6' tiller and dual wheels. She runs great with one huge exception....the hydraulic Shaft seal keeps blowing...and when it does all the hydro fluid runs into the crankcase.
I have changed the bypass valve that feeds the 3pt and PS...I have replaced and re plumbed the hydraulics to be correct...it was feeding the loader first and I've changed that to feed the PS and 3PT then the loader....added new hoses as well.
I have even put a new pump on it (with OLD bypass valve) and sheared the shaft on that.
So..the seals I am getting are from NAPA...they look like the one i pulled out of my new (sheared shaft pump) same material. Im not sure what the heck to do...my pressures are within factory...1500 psi.
Is the pump bad? how do I know what next to replace...
THANKS
