is connected to the solenoid valve bank to prevent
damage.
3. Push the cylinder into the outrigger beam. Align the
cylinder rod with the clevis in the beam. Apply anti-seize
compound to the clevis pin and secure in place with the
clevis pin and cotter pin.
4. Install the outrigger beam. Refer to Outrigger Beam,
page 8-27 in this section. Verify no jack cylinder hose will
be trapped by full outrigger beam retraction.
Functional Check
1. Activate the hydraulic system; extend and retract the
outrigger.
2. Observe the operation of the outrigger beam.
3. Check the hydraulic connections for any evidence of
leakage.
Outrigger Monitoring System (Optional—Standard in
North America)
Description
The Outrigger Monitoring System (OMS) aids the operator in
accurately programming the rated capacity limiter (RCL) by
automatically identifying the position of each outrigger beam.
The OMS uses four sensors, one per outrigger beam, to
identify when an outrigger beam is positioned to one of three
pre-defined locations, including fully retracted, mid-extend,
and fully extended.
Removal
1. Remove the outer access cover plate from outrigger
box.
2. Remove the OMS string potentiometer connector (1,
(Figure 8-24)) from the attaching point on the outrigger
beam.
NOTE: Avoid free-release of cable to prevent damage to
OMS string potentiometer.
3. Disconnect electrical harness connector (2) and secure
to avoid damage.
4. Loosen top mounting hardware enough to disengage
OMS string potentiometer from the slotted top mounting
hole.
5. Completely remove the lower mounting hardware.
6. Remove OMS string potentiometer from inside outrigger
beam.
Installation
1. Install string potentiometer inside outrigger beam.
2. Install the OMS string potentiometer enough to engage
slotted hole with top mounting hardware ((Figure 8-24)).
3. Install the lower mounting hardware.
4. Attach the OMS string potentiometer connector to the
attaching point on the outrigger beam.
NOTE: Avoid free-release of cable to prevent damage to
the OMS string potentiometer.
5. Connect electrical harness connector to string potenti-
ometer.
6. Install access cover plate to outrigger box.
Jack Cylinder
Description
Four jack cylinders are used on the crane, one at the end of
each outrigger beam. The jack cylinders provide the force for
the outrigger beam’s vertical movement. The cylinder weighs
approximately 220.4 lb (100 kg).
Maintenance
NOTE: Refer to Outrigger Extension Cylinder, page 2-86
for disassembly and assembly of the cylinders.
