Illustration 3 g01330289
Control valves (2) are on the frame in front of the cab.
There are eight implement control valves on each machine. There is a maximum of 14 implement control valves that can be installed on each machine. The implement control valves are mounted in two different locations. Valve bank (1) is mounted on the frame near the front of the machine. Valve bank (2) is mounted on the frame in front of the cab. The implement control valves direct oil to the corresponding implements.Shutoff Valve
Illustration 4 g06010139Shutoff valve (3) is on the right-hand frame rail in front of the cab.Implement Pilot Oil Filter
Illustration 5 g01329921Implement pilot oil filter (4) is at the rear of the machine. The implement pilot oil filter removes debris from the pilot oil for the implement solenoids.Control Manifold
Illustration 6 g01329944Control manifold (5) is at the service center near the rear of the machine. Manifold (5) directs pilot oil to the implement control valves.Hydraulic Tank
Illustration 7 g01330269Hydraulic tank (7) is located between the engine and the radiator. Tank (7) stores oil.Piston Pump (Implement and Steering)
Illustration 8 g01330022Piston pump (8) is located below the hydraulic tank. Pump (8) is a variable displacement axial piston pump.Pump Control Valve
Illustration 9 g06030293Pump control valve (9) is attached to the hydraulic and steering pump. Pump control valve (9) keeps pump flow at the level that is needed to fulfill the requirements of the hydraulic and steering system.Oil Filter (Hydraulic Return)
Illustration 10 g01330283Hydraulic filter (10) is located in front of hydraulic tank (7). Filter (10) removes debris from the hydraulic system.Joystick Controls
Illustration 11 g01330284Joystick controls (11) are located inside the cab on both sides of the operator seat. Controls (11) send an electrical signal to the solenoids of the hydraulic system.Steering Control Valve
Illustration 12 g06010142Steering control valve (12) is located in front of the cab. Valve (12) directs hydraulic fluid to the steering system and the implement system.Centershift Lock
Illustration 13 g01329919Centershift lock (13) is on the center of the link bar. The centershift lock prevents the circle from moving to either side of the machine when the centershift lock is engaged.Blade Accumulators (If Equipped)
Illustration 14 g01330080Blade cushion accumulators (14) are mounted on the frame in front of the blade lift cylinders. Accumulators (14) cushion the head end of the cylinder from sudden rises in pressure.
