Pilot Hose Removal and Replacement

Before attempting to remove a servo hose the pilot circuit
accumulator pressure must be vented.
1 Stop the engine. With the operator seat set in the rear
facing position (for backhoe operation), switch the
starter to ON without starting the engine. Operate the
joystick controls several times to vent the servo
pressure from the accumulator. Switch the starter
switch to the OFF position.
2 Note the phasing and routing of the hose to be
renewed. Working under the machine, disconnect the
applicable hose. Note that the hoses have tags to
identify their connections. Plug the open ports. Remove
the hose from any ties under the machine.
3 Working in the cab remove the plastic shrouds A from
the seat as required. Disconnect the hose at the pilot
control valve B. Note that the hoses have tags to
identify their connections Attach some strong string or
cord to the end of the disconnected hose.
