Extension Cylinder
Description
Two outrigger extension cylinders are utilized within each
outrigger box assembly. The extension cylinders provide the
force for the outrigger beam’s horizontal movement. The
cylinder weighs approximately 104.9 lb (47.6 kg).
Maintenance
NOTE: Refer to Outrigger Extension Cylinder, page 2-86
for disassembly and assembly of the cylinder.
Removal
1. Remove the outrigger beam. Refer to Outrigger Beam,
page 8-27 in this section.
2. Remove the cotter pin and clevis pin securing the rod
end of the extension cylinder to the outrigger beam.
3. Pull the extension cylinder from the outrigger beam until
the hydraulic hoses on the rod end of the cylinder can be
accessed. Tag and disconnect the hoses from the rod
end of the cylinder. Cap or plug all openings.
4. Remove the cylinder.
Installation
1. Place the cylinder in the beam.
NOTE: Keep hydraulic fittings and hoses close to angles
shown and as low as possible to prevent rubbing
with the beam top plate and side plate, and for
proper tracking during beam extension and
retraction (Figure 8-23).
2. Position the extension cylinder so the hydraulic ports on
the rod end of the cylinder can be accessed. Connect
the hydraulic hoses to the ports as tagged during
removal. Verify the piston side of the extension cylinder
