Thank you for your reply. The unit is filled with fluid and I purged the system of any air. The fluid retains it"s level so I don"t believe there are any leaks. I"ve replaced the "O" Rings on the main piston after dipping them in hydraulic fluid. I had no problem installing them and don"t believe there are any nicks.
I also replaced the "O" Rings on the control valves but was unable to determine from the Serviceman"s Handbook, GSS-1024, how many "O" Rings should be on the control valve. I believe there are about 4-5 grooves on each control valve where "O" Rings could be but I"m not sure each groove actually should have an "O" Ring.
I have not replaced any "O" Rings on the "check valve actuators" because I wasn"t sure how to remove them.
