RT9130E-2 SERVICE MANUAL UNDERCARRIAGE
carefully lay the end of the cylinder on the bottom of the
outrigger beam or leave on blocking.
NOTE: Do not allow the end of the outrigger extension cyl-
inder to fall when the cylinder mounting shaft is
removed. Use blocking to limit the drop to prevent
damage to the OMS string potentiometer (if
equipped).
OMS string potentiometer may be easily removed
to avoid damage during extension cylinder pin
removal. Refer to Outrigger Monitoring System
(Optional—Standard in North America), page 8-33.
9. After attaching a suitable lifting device of straps or belts
instead of chains to prevent nicking the bottom edges of
the outrigger beam, pull the outrigger beam out of the
outrigger box, re-adjusting the lifting attachment to
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 2132 lb (967 kg).
10. 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 0.125 in
(3.2 mm) 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. Attach the OMS string potentiometer cable (if equipped)
to the attaching point on the outrigger beam.
If the OMS string potentiometer was removed, install the
potentiometer at this time. Refer to Outrigger Monitoring
System (Optional—Standard in North America), page 8-
33.
NOTE: Avoid free-release of cable to prevent damage to
OMS string potentiometer caused by over-range of
cable.
8. Connect the hydraulic lines as tagged prior to removal.
9. Install the side adjustable wear pad in the outrigger box.
10. Adjust the wear pads, refer to Wear Pad Adjustment in
the following section.
11. Install the end cover.
NOTE: At installation, be sure that the outrigger jack
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 in (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 in (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 in (3.0 to 4.5 mm) between shim welded
on beam and side of box. Install and lock set screw
against wear pad.
WARNING
Crushing Hazard!
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.
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
