2. Block all road wheels and place the battery master
switch the 'Off' position.
3. Remove upper pins securing the body cylinders to
body (1) and secure body cylinders clear of the body.
Refer to Section 230-0130, BODY CYLINDER.
4. Using suitable lifting equipment, sling body (1)
assembly at the four lifting points and take an initial
strain.
Note: Approximate weight of body (1) assembly is
5 400 kg (11 905 lb).
5. Remove bolts (5) and washers (6) securing body
hinge pins (3) through body (1) and pin mounting
bores.
6. Remove body hinge pins (3) and shims (4) from
body (1) and remove body (1) assembly from the
vehicle. If necessary, remove bushing (2) from pin
mounting bores.
Note: Do not remove body pads (10) and shims (11 &
12) unless body pads are being replaced.
7. If required, remove locknuts (13), washers (9) and
bolts (8) securing body pads (10) and shims (11 & 12)
to body (1) assembly. Remove and discard body pads
(10) and shims (11 & 12).
INSTALLATION
Numbers in parentheses refer to Fig. 1.
Note: Tighten all fasteners to standard torques listed
in Section 300-0080, STANDARD BOLT AND NUT
TORQUE SPECIFICATIONS.
WARNING
To prevent personal injury and property
damage, be sure wheel chocks and lifting
equipment are properly secured and of
adequate capacity to do the job safely.
1. If removed, install bushing (2) to pin mounting
bores.
2. Using suitable lifting equipment, sling body (1)
assembly and position over the trailer frame.
Note: Approximate weight of body (1) assembly is
5 400 kg (11 905 lb).
3. Align body hinge pin (3) bores in body (1) with bores in
started downward from the fully raised position by
gravity. When the body starts lowering by gravity, the
joystick can be released and internal valve springs will
move the joystick to the 'HOLD' position.
'HOLD' - Moving the joystick to this position while the
body is being raised or lowered traps the oil in the
body hoists to stop and hold the body at any desired
height. The joystick will remain in the 'HOLD' position
when released.
'RAISE' - Pushing the joystick back and holding it in
this position directs oil to extend the body hoists and
raise the body. When released, the joystick will be
spring-returned to the 'HOLD' position.
Note: The body control lever must remain in the
'FLOAT' position until it is necessary to operate the
body again. Failure to comply to this could result in
overheating the hydraulic oil and failure of the
hydraulic system components.
Note: A proximity sensor (19) prevents the body (1)
being fully powered down onto the chassis. At a
predetermined height, the sensor automatically
defaults the body control valve to the detented
'FLOAT' condition.
Note: If the body-up warning light goes out while the
body is being raised, the 'POWER DOWN' operation
will not be available and the body control valve will
automatically default to the detented 'FLOAT'
condition. The cause of the electrical fault must be
investigated and corrected.
REMOVAL
Numbers in parentheses refer to Fig. 1.
WARNINGS
To prevent personal injury and property
damage, be sure wheel chocks and lifting
equipment are properly secured and of
adequate capacity to do the job safely.
Exercise extreme caution when lowering
the cylinders from the body. The cylinders will
swing out sharply as they leave their
mountings.
1. Position the vehicle in a level work area, ensure the
body is fully lowered, apply the parking brake and
switch off the engine. Turn steering wheel several
times to relieve any pressure in the steering circuit.
