SHUTOFF GP-AIR 4923432 - Caterpillar

The implement hydraulic system is composed of the following systems:
implement electronic control system
main hydraulic system
ride control system
kickout system
fan drive systemThe hydraulic oil tank (30) is common to all of the systems.The implement electronic control system is made up of the following components:
(14) pilot valve (oil manifold)
(24) pilot/brake pump
(28) implement electronic control module
(31-33) lever detent coils
(35-37) switches
(38-40) lever position sensorsThe main hydraulic system is made up of the following components:
(1) main control valve
(2) auxiliary cylinders
(3) tilt cylinder
(4) lift cylinders
(8) main relief valve
(15) implement pumpThe ride control system is made up of the following components:
(4) lift cylinders
(5) manifold
(6) ride control diverter valve
(7) ride control accumulator
(28) implement electronic control moduleThe kickout system is made up of the following components:
(14) pilot valve (oil manifold)
(28) implement electronic control module
(31-33) lever detent coils
(38-40) lever position sensors
(41) lift position sensor
(42) bucket position switchReference: For additional information on the operation of the kickout system, refer to Systems Operation, "Kickout System (Electro-Hydraulic System)".The fan drive system is made up of the following components:
(16) flow diverter valve
(17) front axle oil cooler
(18) hydraulic oil filter
(20) rear axle oil cooler
(21) hydraulic oil cooler
(22) hydraulic oil cooler bypass valve
(26) fan drive pump

(13) Lowering valve (dead engine lower). (14) Pilot valve (oil manifold). (15) Implement pump. (21) Hydraulic oil cooler. (24) Pilot/brake pump. (26) Fan drive pump. (27) Fan drive motor. (28) Implement electronic control module. (30) Hydraulic oil tank.Implement pump (15) and pilot/brake pump (24) are located under the cab. The pilot/brake pump and the steering pump (23) mount in-line to the torque converter housing. The implement pump and the transmission pump are mounted in-line to the torque converter housing.Hydraulic oil tank (30) is located under the cab on the right side of the machine. Breaker relief valve (25) is mounted on the side of hydraulic oil tank. When the operator depresses the breaker relief valve the pressure inside the hydraulic oil tank is released.Machines with the optional ride control system have a ride control diverter valve that attaches to manifold (5). Ride control diverter valve (6) controls the flow of oil to ride control accumulator (7). The ride control accumulator is located in front of the articulation joint on the right side of the front end frame.Reference: For additional information on the operation of the ride control system, refer to Systems Operation, "Ride Control System".The valve for dead engine lower (13) is located in front of the articulation joint. The valve for the dead engine lower is used in order to lower the lift arms when there is an electrical failure.Implement electronic control module (28) is located on the right side and the rear of the cab.
