(Optional)
a. Removal
1. Place the boom in a horizontal position.
2. Using the auxiliary hydraulics control lever,
swing the carriage to the centered position.
3. Lower the boom until the carriage is resting
firmly on the ground.
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 swing car-
riage cylinders (1, Fig. 9.35) and hydraulic
lines (2 and 3).
7. Tag and disconnect the hydraulic lines (2 and
3) from the cylinders (1) and cap and plug the
open connections.
8. Remove bolt and nut holding the center
mounting pin (4) to the pivot mount (5).
Remove the pin.
9. Remove snap rings (6) and cylinder base end
pins (7) from the mounting plates on the
carriage. Identify and mark the location of the
1-1/2" I.D. shims (10) at the base end of the
cylinder.
10. Remove the cylinders from the pivot mount
and the mounting plates using a strap sling
and hoist or other suitable lifting equipment.
While removing the cylinders identify the
locations of the 2" I.D. shims (9) at the rod
ends of the cylinders. Be careful not to lose
the bearings (8) in each of the cylinder rod
ends.
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.

b. Disassembly
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.
3. Remove counterbalance valve (11 Fig. 9.36),
relief valve (12) and the O-rings and back-up
rings. Remove the orifice (13) from the valve
block.
4. Using a pin spanner wrench, unscrew gland
(7, Fig 9.36) 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.
