ADAPTER GP-OIL LINE 1922968 - Caterpillar

Illustration 7 g03125258The switch is two directional. The switch has three pins that connect to the ECM. The fourth function is normally controlled by the lever. The use of this switch allows the lever to be used for a separate function. This switch could be used to operate the fire plow. Depressing and holding the switch in one direction actuates the raise solenoid for the fourth function. Holding the switch in the other direction actuates the lower solenoid for the fourth function. This switch allows control of the fourth function.Winch Free Spool
Illustration 8 g01642417Push the switch to release the winch cable. The winch cable unreels by manually pulling the winch cable. Machine or hydraulic assistance is not needed. The winch will remain in the FREE SPOOL position until the switch is pressed again or until any other function of the winch is activated.Note: Activating the switch allows the spool to move without tension on the cable. The cable can become tangled when the cable is allowed to move without tension applied to the cable.Winch Drive Away
Illustration 9 g01642474Push the DRIVE AWAY switch to release the winch brake. This function will also activate the DRIVE AWAY solenoid. When the drive away solenoid is energized, the solenoid valve sends pilot hydraulic pressure to the drive away valve. The drive away valve opens, which connects the motor ports together and allows the motor to turn independently of the closed circuit hydraulic pump. The resistance of the motor is then seen from the spool. As speed increases past an “over speed” point the resistance is increased through a Hydromechanical valve. The load will begin to drag behind the machine and limit the reel out speed. Tension is held on the cable to prevent the cable from becoming tangled. When the drive away solenoid is not energized, the valve is closed by a spring. The hydraulic flow from the closed circuit hydraulic pump may flow to the motor parts for the winch as required for the reel-in and the reel-out functions.Outputs
On/Off Solenoids
Implement Solenoid

Implement lockout solenoid
The implement lockout solenoid valve is an On/Off type of solenoid valve. The implement lockout valve is designed to prevent the movement of the blade and an optional attachment. The flow of oil through the implement pilot manifold is blocked when the solenoid is de-energized.The solenoid affects the system in the following manner:LOCKED - The implement lockout solenoid is de-energized. The implement system is no longer operable.UNLOCKED - The implement lockout solenoid is energized. The implement system is enabled.Proportional Solenoids

Each of these solenoids is designed to control pilot pressure to the corresponding winch movement system. The ECM will adjust the solenoid valves according to the request that is made by the operator through the winch controls. These solenoid valves are the proportional type of solenoid valve. The ECM uses a pulse width modulated signal (PWM) to vary the
