UNDERCARRIAGE RT9130E SERVICE MANUAL
prevent the extension cylinder from sliding out of the
outrigger beam when the beam clears the outrigger box.
NOTE: The outrigger beam assembly weighs
approximately 967 kg (2132 pounds).
9. Position the outrigger beam on the blocking material.
Inspection
Inspect the outrigger beams for bends, evidence of cracks,
or other damage. Check the outrigger beam internally for
hydraulic fluid, which may indicate a leaking cylinder, loose
connection, or damaged hydraulic line.
Installation
1. Apply grease (EP-MPG) to the bottom of the outrigger
beam.
2. If removed, install the side adjustable wear pad in the
outrigger beam.
3. Install the bottom wear pads with approximately 3.2 mm
(0.125 in) protruding. This will prevent the beam side
plates from riding on the bottom of the box.
4. Attach a suitable lifting device of straps or belts instead
of chains to prevent nicking the bottom edges of the
outrigger beam.
5. Slide the beam into the outrigger housing and align the
cylinder bushing with the mounting hole.
6. Apply anti-seize compound to the clevis pin. Secure the
cylinder barrel to the housing with the clevis pin and
cotter pin.
7. Connect the hydraulic lines as tagged prior to removal.
8. Install the side adjustable wear pad in the outrigger box.
9. Adjust the wear pads, refer to WEAR PAD
ADJUSTMENT in this Sub-Section.
10. Install the end cover.
NOTE: At installation, be sure that the outrigger stabilizer
cylinder hydraulic hoses are not trapped against
the outrigger box when the beam is fully retracted.
Wear Pad Adjustment
NOTE: When adjusting wear pads, refer to (Figure 8-22).
1. Adjust each of the bottom wear pads (about 1/2 turn)
until there is a gap of 0.12 to 0.18 inch (3.0 to 4.5 mm)
between the top of the beam and the top of the outrigger
box. Install and lock set screws against wear pads.
2. Adjust outrigger box side wear pad until there is a gap of
0.12 to 0.18 inch (3.0 to 4.5 mm) between beam and
shims welded in top and bottom of box. Install and lock
set screw against wear pad.
3. Adjust outrigger beam side wear pad until there is a gap
of 0.12 to 0.18 inch (3.0 to 4.5 mm) between shim
welded on beam and side of box. Install and lock set
screw against wear pad.
DANGER
Be sure any blocking material used is capable of
supporting the weight of the outrigger beam. Do not allow
it to tilt or slide.
CAUTION
Be sure that the piston side of all outrigger cylinders are
connected to the solenoid valve bank. Reversal of port
connection of the rod and piston sides could result in
severe damage to the cylinders as very high pressure
intensification will occur.
CAUTION
During initial start-up and checking of the outrigger
operation, each control switch must be operated before
operating the selector valve. If hydraulic lines are
reversed to one or more cylinders, this will prevent
damage to the cylinders
