CAB ASSEMBLY WITH ROPS/FOPS MAINTENANCE - CONTINUED
REMOVAL - CONTINUED
Do NOT remove hydraulic tank filler cap or disconnect or remove any hydraulic system line or fitting
unless hydraulic system pressure has been relieved. Hydraulic system pressure can be over 3,000 psi
(20685 kPa), even with engine and pump OFF. To relieve pressure, lower all hydraulic attachments to
the ground and shut down engine. Move control levers through all operating positions, then SLOWLY
loosen hydraulic tank filler cap. After maintenance, tighten all connections before applying pressure.
Escaping hydraulic fluid under pressure can penetrate the skin, causing injury or death.
At operating temperature hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any
hydraulics. Failure to do so could result in injury.
Wipe area clean around all hydraulic connections to be opened during removal and disassembly. Cap oil
lines and plug holes after removing lines. Contamination of hydraulic system could result in premature fail-
If more than one hydraulic line is removed, tag lines to ensure proper installation. Use container to catch any
hydraulic oil that may drain from system.
Disconnect two hydraulic steering control lines at priority valve (WP 0143 00).
Disconnect six hydraulic lines from hydraulic joystick, four at boom control valve, one at shuttle valve (WP 0181 00).
Disconnect one hydraulic line from transmission disconnect master cylinder at transmission control valve (WP 0122
Disconnect four hydraulic brake lines; one at each brake tee and two at frame tilt/brake relief valve (WP 0133 00).
Disconnect hydraulic line at tee of all four steering cylinders (WP 0141 00).
Disconnect hydraulic lines at frame tilt cylinder port (WP 0183 00).
Disconnect hydraulic line at hydraulic piston pump (WP 0174 00).
Remove nuts (12 and 13), grounding strap (11) and starwashers (14 and 15). Discard starwashers.
Attach a suitable sling and a lifting device to cab. Raise lifting device to take up slack.
Remove four nuts (16), eight flatwashers (17), two washers (shims) (19), four rubber washers (18), two capscrews (20)
and two capscrews (21).
