Do not attempt to remove the main hydraulic pump with four nuts "X" that hold the pump to the adaptor and the flywheel housing. The bolts are required to be tightened from the coupling side of the adaptor, therefore the main hydraulic pump can only be removed by removing the bolts that hold the adaptor to the flywheel housing.
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. To prevent possible personal injury, release the pressure in the implement hydraulic circuits (the boom, the stick and the bucket) before any of the hydraulic lines or any of the components are disconnected or removed.
1. Release the pressure in the implement hydraulic circuits (the boom, the stick and the bucket) before any of the hydraulic lines or any of the components are disconnected or removed. Release the pressure as follows:a. Shut off the engine and place key in the "ON" position. Put the hydraulic activation control lever in the "UNLOCK" position.b. Move the control levers for the boom, the stick and the swing to all full stroke positions. This will release any pressure that might be present in the pilot system.c. Return the key to "OFF" position.d. Slowly loosen the fill plug on the hydraulic tank, and release the pressure.e. Tighten the fill plug on the hydraulic tank.f. The pressure in the hydraulic system has been released, the lines and the components can be removed. Drain the hydraulic tank oil in a suitable container for storage or disposal.2. Drain the oil from the hydraulic oil tank into a suitable container for storage or disposal. The capacity of the hydraulic oil tank is 99 liters (26 U.S. gal). 3.
