Joystick Assembly Installation
1. As required, carefully remove the rubber boot from
the joystick by pulling the boot off the joystick base
(Fig. 414) and lifting it over the joystick handle. Save
the boot for installation later.
Note: If installing a new joystick assembly, label or per-
manently mark the hose ports on the underside as
shown in Fig. 424. Remove any port plugs before pro-
ceeding.
2. Place the joystick in a vise or other suitable device.
Install new small and large O-rings and the six
straight fittings into the joystick valve ports
(Fig. 424) if necessary. To help avoid leaky
connections, always use new O-rings when servicing
the vehicle.
3. Position the joystick assembly above its mounting
hole in the console. Remove the plug from the hose
labeled "P" and secure the hose to the "P" port of the
joystick valve.
4. Remove the plug from the hose labeled "T" and
secure the hose to the "T" port of the joystick valve.
Remove the plugs from the remaining hoses one at a
time and secure each hose as labeled to the proper
fitting on the joystick control valve. Tighten all fittings
securely.
5. Position the lower joystick wires as indicated in Fig.
4–22. Reach in through the logic panel opening and
guide the wires up through the logic panel opening
while lowering the joystick assembly down into its
mounting hole in the console.
