Extension
Cylinder
Description
The outrigger extension cylinder is a combination unit with
two rods, one for extending each direction. 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 (fly)
beam.
Each barrel has a 6.4 cm (2.50 in) diameter bore. Internal
seals are used to prevent internal and external leakage. A
wiper ring is mounted to the front of the barrel to wipe dirt
from the rod as it is retracted.
The overall retracted length of the cylinder assembly is 183.4
cm (71.93 in) from the center of the rod mounting hole to the
center of the other rod mounting hole. The lower barrel has a
stroke of 119.4 cm (47.00 in) and the upper barrel has a
stroke of 130.8 cm (51.50 in). The fully extended length is
433 cm (169.33 in).
Each cylinder weighs approximately 86 kg (190 lb).
Maintenance
NOTE:
Refer to Cylinders, page 2-29 for Disassembly and
Assembly of the cylinders.
Removal
1.
Remove the outrigger beam.
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.
2.
Connect the lines to the jack cylinder as marked during
disassembly.
3.
Secure the hoses in place with the bolts, pipe clamps
and bolt inserts.
4.
Install the shaft securing the rod end of the extension
cylinder to the outrigger beam.
5.
Install the outrigger beam. Refer to paragraph
Beam (with Adjustable Wear Pads)
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 JACK CYLINDERS
Description
The jack cylinders have 14.0 cm (5.50 in) diameter bores
and are the double-acting type. The cylinders are pinned into
tubes welded onto the end of the outrigger beams. A port
block is welded to the end of the cylinder rod and a pilot-
operated check valve is threaded into the port block. Internal
seals are used within the cylinder to prevent internal and
external leakage. A wiper ring is mounted to the front of the
cylinder barrel to wipe dirt from the rod as it is retracted.
The cylinders have a retracted length of 109.5 cm (43.12 in)
from the center of the mounting fixture on the barrel to the
end of the rod. The fully extended length is 160.3 cm
(63.12 in). The stroke is 50.8 cm (20.00 in)
Each cylinder weighs approximately 89 kg (196 lb).
Maintenance
NOTE:
, page 2-29 for Disassembly and
Assembly of the cylinders.
Removal
1.
Extend the outrigger beam slightly for improved access
to the jack cylinder. Shut down the engine.
2.
Tag and disconnect the hydraulic hoses from the jack
cylinder.
3.
Remove the cylinder cap.
4.
Place a jack capable of supporting the weight of the jack
cylinder at the base of the cylinder barrel. Jack up the
cylinder just enough to relieve any pressure on the
cylinder retaining pin.
CAUTION
Damage Could Occur!
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 cold result in
severe damage to the cylinders as very high pressure
intensification will occur.
