Component Location for Main Hydraulic System (1) Implement pump. (2) Main control valve. (3) Lift cylinder. (4) Hydraulic tank. (5) Tilt and tip cylinder ( 834H Wheel Dozer). 834H Wheel Dozer
The implement system uses an open center electro-hydraulic control valve (2) . The main control valve has three stems. One valve stem is used to control each of the following circuits: lift circuit, tilt circuit and tip circuit. The main control valve is supplied hydraulic oil by the implement pump (1) .The main control valve regulates the flow of hydraulic oil to the lift cylinder (3) and the tilt and tip cylinders (5) . The main control valve contains relief valves for the implement pump and the implement circuits. 836H Landfill Compactor
The implement system uses an open center electro-hydraulic control valve. The main control valve (2) has a single stem that is used to control the lift function. The main control valve receives hydraulic oil from a single gear pump. The main control valve is supplied hydraulic oil by the implement pump (1) .The main control valve regulates the flow of hydraulic oil to the lift cylinder (3) . The main control valve contains relief valves for the implement pump and the lift circuit. Schematic for 834H Wheel Dozer and 836H Landfill Compactor Machines
