(Optional)
a. Removal
1. Place the boom in a horizontal position.
2. Using the side tilt control lever, tilt the carriage
fully to the left to retract the side tilt cylinder.
3. Support the side tilt carriage (7, Fig. 9.20) in
this position with blocking.
4. Engage the park lock, place the travel select
lever in neutral, and stop the engine.
5. Operate the hydraulic controls after the engine
has stopped to relieve any trapped pressure.
6. Remove all dirt and grease from side tilt
carriage cylinder (1) and hydraulic lines (2 and
3).
7. Disconnect the hydraulic lines from the
cylinder and cap and plug the open connec-
tions.
8. Remove snap ring (4) and cylinder rod pin (5)
securing the side tilt carriage cylinder rod to
side tilt carriage (7).
9. Remove snap rings (4) and cylinder base pin
(6) securing the side tilt carriage cylinder tube
to pivot base (8).
10. Remove the cylinder from the pivot base using
a strap sling and hoist or other suitable lifting
equipment.

1. Remove any remaining dirt and grease from
the cylinder.
2. Fasten the cylinder in a soft-jawed vise or
other acceptable holding equipment. Do not
damage the tube.
Warning !
Warning !
Relieve hydraulic pressure before servicing any
hydraulic component. Escaping hydraulic fluid
under pressure can penetrate the skin causing
serious injury.
Wait for the hydraulic fluid to cool before servic-
ing any hydraulic component. Hot hydraulic fluid
can cause severe burns.
3. Remove check valves (2) and three O-rings
(15) and backup rings (16).
4. Using a pin spanner wrench, unscrew gland
(4, Fig 9.21) from the tube (1).
IMPORTANT: Protect the finish on the rod at
all times. Damage to the surface of the rod can
cause premature seal failure.
5. Pull rod (5) and attached parts straight out of
the tube.
IMPORTANT: When sliding the rod and piston
assembly from the tube, be careful so that gland
threads in the tube do not damage the piston.
Keep the rod in line with the tube barrel to prevent
binding.
6. Fasten the eye end of the rod (5) in a soft-
jawed vise and put a support below the rod
near the piston to prevent damage to the rod.
