4. Slide the beam into the outrigger housing and align the
cylinder rod with the mounting hole.
5. Secure the cylinder rod to the housing with the clevis pin
and cotter pin.
6. Secure the tube assemblies to the housing using bolts,
washer, lockwashers and nuts.
7. Attach the OMS string potentiometer cables (if
equipped) to the attaching point on the outrigger beams.
If the OMS string potentiometers were removed, install
the potentiometers at this time. Refer to Outrigger
Monitoring System (Optional—Standard in North
America), page 8-70.
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 pads in the outrigger
box.
10. Adjust the wear pads. Refer to Wear Pad Adjustment.
11. 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 8-75.
1. Adjust the bottom wear pads (approximately 1/4 turn)
until a gap of 1.5 mm (0.06 in) is obtained at the tightest
point during full extension. Install and lock setscrews
against wear pads.
2. Adjust outrigger box side wear pads until a gap of 1.5
mm (0.06 in) is obtained at the tightest point during full
extension. Install and lock setscrews against wear pads.
EXTENSION CYLINDER
Description
The outrigger extension cylinder is a combination unit with
two rods, one for extending each beam section. Each “half”
of the cylinder is a double-acting type cylinder. The barrel
end is attached to the mid beam. The lower rod is attached to
the outrigger box and the upper rod is attached to the jack
beam.
Each barrel has a 6.4 cm (2.50 in) diameter bore. Internal
seals are used to prevent internal and external leakage.
Each cylinder weighs approximately 70.3 kg (154.9 lb).
NOTE: Refer to Cylinders, page 2-54 for Disassembly and
Assembly of the cylinder.
Removal
1. Remove the outrigger beam. Refer to Outrigger Beam
Removal in this section.
2. Remove the bolts, pipe clamps, and bolt inserts,
securing the hoses to the inside of the beam.
3. Remove the shaft securing the rod end of the extension
cylinder to the outrigger beam.
4. Withdraw the cylinder until the rod end is exposed.
5. Tag and disconnect the lines to the jack cylinder. Cap all
lines and openings.
Installation
1. Install the extension cylinder into the outrigger beam.
NOTE: Keep hydraulic fittings and hoses as low as
possible to prevent rubbing with the beam top plate
and side plate, and for proper tracking during beam
extension and retraction.
2. Connect the lines to the jack cylinder as marked during
disassembly.
CAUTION
Make 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.
CAUTION
Make 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.
