SPACER 2038115 - Caterpillar

Illustration 2 g00920264The hydraulic tank is not vented. The hydraulic tank contains a reverse flow element. The hydraulic tank is located directly behind the operator's cab.Hydraulic and Steering Pump
Illustration 3 g00920265The hydraulic and steering pump is a variable displacement axial piston pump. The hydraulic and steering pump is located below the cab in front of the engine.Pressure and Flow Compensator Valve (Hydraulic and Steering)
Illustration 4 g00920277The pressure and flow compensator valve for the hydraulic and steering keeps the pump pressure and the pump flow at the level that is needed to fulfill the requirements of the hydraulic and steering system. The pressure and flow compensator valve is attached to the hydraulic and steering pump.Combination Valve
Illustration 5 g00920267The combination valve directs hydraulic fluid to the steering system and the implement system. The combination valve is located underneath the cab next to the hydraulic and steering pump.Steering Priority Valve
The steering priority valve establishes a priority to the steering circuit before the implement circuit. Steering Relief Valve
The steering relief valve limits the maximum pressure that is allowed to the steering circuit. The steering relief valve is set at 19300 689 kPa (2800 100 psi).Implement Relief Valve
The implement relief valve protects the hydraulic and steering pump from excessively high pressures. The implement relief valve is set at 26900 kPa (3900 psi).Load Check Valve
The load check valve maintains the steering accumulator pressure at the inlet of the steering metering pump. This pressure will allow a more responsive steering operation.Signal Resolver Valve
The signal resolver valve selects the higher of the two signal pressures from the steering circuit and the implement circuit. The highest signal is then routed to the pressure and flow compensator valve.Signal Relief Valve
The signal relief valve limits the maximum implement signal pressure. The signal relief valve is set at 22050 kPa (3200 psi).Signal Purge Valve
The signal purge valve allows the signal pressure to go to the hydraulic tank when the implement controls are returned to the HOLD position.Centershift Lock Cylinder
Illustration 6 g00920877Centershift lock cylinder is located on the rear of the link bar. When the lock pin is not engaged with the arm assembly, the arm assembly and the circle can be moved in order to place the blade in the correct position.Steering Accumulator
Illustration 7 g00920270The steering accumulator prevents the momentary interruption in the steering operation that is caused by sudden changes in pump demand. The steering accumulator is mounted to the combination valve.Steering Metering Pump
Illustration 8 g00920271The steering metering pump directs hydraulic oil to the right steering cylinder and to the left steering cylinder. The steering metering pump is located inside the steering column.Implement Control Valves
Illustration 9 g00920274There are typically eight implement control valves on each machine. There is a maximum of fourteen implement control valves that can be installed on each machine. The implement control valves direct oil to the corresponding implement. The implement control valves are located underneath the cab.Fan Drive Pump
Illustration 10 g00923120The fan drive pump is a variable displacement axial piston pump. The fan drive pump is mounted on the hydraulic and steering pump.
