Rubber Track Loader

9. Loader/Transmission Controls Disassembly and Assembly

9-2

Loader Control Joystick Operation – The right-
hand joystick controls the loader arm and the at-
tachment tilt cylinder. It allows the operator to raise,
lower and pivot the attachment. The joystick oper-
ates on hydraulic charge pressure.

The loader control also has a float position, which is
activated by moving the joystick completely forward
until it “detents”. The joystick is held in the forward
float position by an electromagnet.

The tools required for loader/drive control joystick
removal and installation are listed in Table 9-1. Use
manufacturer-recommended tools whenever possi-
ble.

Table 9-1

Loader Control Joystick/Drive Control
Joystick Removal

Note: Since the procedures for removing both joystick
controls are identical, only the loader control joystick pro-
cedure is described below.

Note: During disassembly, cap all hoses and fittings to
prevent fluid loss and contamination of the system fluids.

! WARNING !

Lower all attachments and make sure the oil is cool
before removing any components or lines. Hot oil can
cause personal injury.

1. Lower the lift arms to the ground.

2. Turn the engine start switch to the OFF position.

3. Relieve hydraulic pressure from the auxiliary

circuit.
