Component locations (1) Test port for the pilot oil pressure in the pressure reducing valve. (2) Combination valve 924G. (3) Pressure reducing valve. (4) Test port for the steering pressure in the pressure reducing valve. |
The pressure reducing valve is located on the right side of the machine under the operator's platform. The valve controls the pressure in the pilot system.
The test port (1) for the pilot oil pressure is located on the pressure reducing valve.
When a pilot control valve is moved out of the HOLD position, the pilot control valve directs the flow of pilot oil to a valve spool in the bank valve. This causes the valve spool to shift in order to allow high pressure oil from the piston pump to flow to the work tools.

Control lever (5), control lever (6), and control lever (7) are located on the right side of the operator station. The shutoff for the pilot valve (8) is located on the right side of the operator station next to the seat. Auxiliary control lever (6) actuates the optional auxiliary pilot valve. Auxiliary control lever (7) actuates the optional auxiliary pilot valve.
The standard implement hydraulic system consists of a joystick control for the lift control and the tilt control.
The joystick in the lift position causes oil to flow into the head end of the lift cylinders in order to raise the work tool.
The joystick in the lower position causes oil to flow into the rod end of the lift cylinders in order to lower the work tool.
The 924G machine uses a VersaLink front end. Because of the VersaLink design, the orientation of the tilt cylinder is different from the design of the 924Gz machine with the Z Bar front end.
The joystick in the dump position causes oil to flow into the head end of the tilt cylinder in order to dump the bucket for the 924G machine.
The joystick in the tilt back position causes oil to flow into the rod end of the tilt cylinder in order to tilt back the bucket for the 924G machine.
The joystick in the dump position causes oil to flow into the rod end of the tilt cylinder in order to dump the bucket for the 924Gz machine.
The joystick in the tilt back position causes oil to flow into the head end of the tilt cylinder in order to tilt back the bucket for the 924Gz machine.
The switch for the solenoid valve (hydraulic lockout) (8) is used in order to block the flow of oil to the pilot valves. Press the top of switch (8). The shutoff for the pilot valve (8) is in the LOCKED position. The pilot oil to the pilot control valves is blocked. This prevents operation of the implement even though the operator can still move the control levers.
A machine that is equipped with an implement hydraulic system with a third function has one auxiliary control valve.
Move the lever forward for the third function hydraulic arrangement. This causes oil to flow into the one side of the auxiliary circuit.
Move the lever backward for the third function hydraulic arrangement. This causes oil to flow into the other side of the auxiliary circuit.
A machine that is equipped with an implement hydraulic system with a fourth function has two auxiliary control valves.
Move the lever forward for the fourth function hydraulic arrangement. This causes oil to flow into the one side of the auxiliary circuit.
Move the lever backward for the fourth function hydraulic arrangement. This causes oil to flow into the other side of the auxiliary circuit.
