Should oil at the inlet side of the valve exceed
221 bar (3 200 lbf/in²), pilot poppet (33) will be forced
off its seat. Oil will flow through an internal passage
and exit from port 'B' to the hydraulic oil tank. When
pressure is relieved, tension of spring (32) will force
pilot poppet (33) to re-seat.
REMOVAL
Numbers in parentheses refer to Fig. 1.
WARNINGS
To prevent personal injury and property
damage, be sure wheel blocks, blocking
materials and lifting equipment are properly
secured and of adequate capacity to do the job
safely.
Hydraulic fluid pressure will remain
within the body hoist system after engine
shutdown. To prevent personal injury and
property damage, press and hold down body
hoist bleed down switch and operate the body
control joystick continually to relieve pressure
in the system.
1. Position the vehicle in a level work area, apply the
parking brake and switch off the engine.
2. Press and hold down body hoist bleed down switch
and operate the body control joystick continually to
relieve pressure in the body hoist system.
3. Block all road wheels, place the steering lock bar in
the 'Locked' position and the battery master switch in
the 'Off' position.
4. Remove hydraulic tank anti-spill drain cap, install
drain tube connection and drain oil into a suitable
container. Remove drain tube connection and reinstall
cap.
5. Clean body control valve housing (28) and
surrounding area with a suitable solvent. Identify and
tag all hydraulic and servo control lines connected to
body control valve, to aid in 'Installation'.
6. With suitable containers available to catch spillage,
disconnect hydraulic and servo control lines from
control valve. Drain the oil from the lines into the
container and discard all 'O' rings. Cap hydraulic lines
and control valve ports to prevent ingress of dirt.
Body System - Body Control Valve
7. Support body control valve with a suitable lifting
device and remove mounting hardware securing body
control valve to mounting bracket on the frame.
Remove body control valve from the machine and
transfer to a clean area for disassembly.
DISASSEMBLY
Numbers and letters in parentheses refer to Fig. 1.
WARNING
Spring loaded parts. Use care when removing
end cap, retainers and plugs to prevent sudden
release of spring tension behind these parts.
Personal injury or property damage could
result if care is not taken.
Note: Clean entire control valve assembly with a
suitable solvent and dry thoroughly prior to
disassembly.
Valve Body
1. If required, remove adaptor and 'O' ring from port 'E'
in valve housing (28). Discard 'O' ring.
2. If required, remove bolts (23), lockwashers (24),
blanking plate (25) and 'O' ring (26) from port 'A' in
valve housing (28). Discard 'O' ring (26).
Control Spool
1. Clean the entire body control valve assembly with a
suitable solvent and dry thoroughly. Remove caps
from valve housing (28) ports.
2. If required, clamp body control valve assembly in a
soft jawed vice. Take care to avoid damaging valve
housing (28) machined surfaces.
3. Remove capscrews (14) securing pressure
reducing valve (13) from mounting block (20).
Withdraw pressure reducing valve (13) from mounting
block (20).
4. Remove capscrews (22) securing mounting block
(20) to end cap (10). Remove mounting block (20) and
discard 'O' ring (21).
5. If required, remove plug (19) from mounting block
(20) and discard 'O' ring (18).
6. Repeat steps 3 to 5 for opposite end of valve
housing (28), end cap (17).
