OPERATION
The pilot valve casing contains a vertical shaft hole with a reducing valve incorporated into it. When the handle is tilted, the push rod and spring seat are pushed down changing the secondary pressure spring’ s pressure.
The casing provides the inlet port P (the primary pressure) and the tank port T. The secondary pressure commensurate with the variation of the operation angle of the handle (1) is taken out through the output ports A and B below the vertical shaft hole. The secondary pressure functions as the pilot pressure to actuate the spool of the control valve (2).
When the Handle (1) is at the Neutral Position:
The force of the spring (3) for setting the secondary pressure that determines the output pressure of the pilot valve is not conveyed to the spool (4). Therefore, the spool (4) is pushed up by the return spring (5), and the output ports A and B are connected with the tank port T, making the pressures in the ports A and B equal to the pressure in the tank port T.
When the Handle (1) is Tilted:
When the handle (1) is tilted and the push rod (6) is pushed, the spool (4) moves downward and the input port P is connected with the output port A. Then, the oil from the pilot pump flows into the output port A, generating a pressure.

1. Heater Core
Heater cores are like small radiators. The fin and tube construction is designed to route coolant flow for the best possible heat energy transfer from coolant to cab air. Hoses from and to the engine are connected to the core with clamps. The core outlet may be larger or the same size as the inlet.
2. Water Valves
Water valves may be cable, vacuum or air controlled. The valve can be either open, closed or set part way open. Some valves have a bypass design to return coolant to the engine. Most are manually controlled although electronic systems are now being installed.
3. Defrosters and Ducts
Defrosting is accomplished by directing heated dry air through ducts to the windshield. The heater system serves the dual purpose of defrosting and heating. Controls are used to route the air flow to the windshield and occupant areas by opening and closing duct doors. Controls may be manual, air or vacuum.
Many vehicles use a “defrost interlock” system which utilizes the air conditioner to dry the defrost air and clear the cab windows more quickly.
4. Blowers and Fans
Blowers or fans are used in the system to move cab air through the heater core and evaporator. Air can be pushed or pulled through the core depending on system design. Blower or fan speed is usually selected by the operator.

HYDRAULIC PUMP
OPERATION
Piston Pump
This pump is a variable displacement piston pump with a single cylinder block, which discharges two equal volumes.
Ten pistons (2) are installed in the cylinder block (1), and the end surface is in contact with the valve plate (3). The suction port C and the discharge port A of the pump P1 and the discharge port B of the pump P2 are arranged in the valve plate (3). On the other hand, the swash plate (4) is fastened to the housing at a given inclination, and the pistons (2) rotate along this swash plate (4).
When the shaft (5) is rotated, the cylinder block (1) rotates, the pistons (2) in the cylinder block execute reciprocating movement along the swash plate (4), and the pump executes suction and discharge. At this time, the pistons in contact with the discharge port A of the valve plate (3) operate as the pump P1, while the pistons in contact with the discharge port B operate as the pump P2.
In this way, the ten pistons (2) execute one suction and discharge stroke with each revolution of the cylinder block (1), so that suction and discharge are executed continuously when the shaft (5) is rotated continuously.
As the piston stroke displacement depends on the inclination of the swash plate (4), the discharge flow quantity can be changed by changing the inclination of the awash plate (4).

INTERFERENCE PREVENTION SYSTEM
MACHINE CONFIGURATION

OPERATION
The interference prevention system detects the boom position by the cams (1), (2) and (3) and the boom switches A, B and C; and detects the offset arm position by the angle (4) and the offset switches B and A. When the attachment enters the interference area, the solenoids C, 1, 2 and 3 of the solenoid valve are switched by the detected signal to control the spools of the boom section (5) and the offset section (6) of the control valve. Then, the boom cylinder (7) raise is decelerated and stopped, and the left offset of the offset cylinder (8) is stopped, thus preventing interference between the attachment and the cab.
