Boom Extension Cylinder
How to Remove the Extension
Cylinder
Note: When removing a hose assembly or fitting,
the O-ring on the fitting and/or hose end must be
replaced and then torqued to specification during
installation. Refer to Section 2,
Hydraulic Hose and
Fitting Torque Specifications.
1 Raise the boom to a horizontal position.
2 Tag, disconnect and plug the hydraulic hoses at
the boom extension cylinder manifold. Cap the
fittings.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
Component damage hazard.
Hoses can be damaged if they are
kinked or pinched.
3 Attach a lifting strap from an overhead crane to
the center point of the boom extension cylinder.
Support the cylinder. Do not apply any lifting
pressure.
4 Remove the extension cylinder support loop
from the underside of the boom.
Note: The extension cylinder support loop is
located at the fork end of the boom.
5 Remove the fasteners securing the extension
cylinder pivot pins to the boom.
6 Use a soft metal drift to remove both pivot pins.
Remove the cylinder from the machine.
Crushing hazard. The boom will
fall if not properly supported when
the pivot pins are removed from
the machine.
Note: During removal, the overhead crane strap
will need to be adjusted for proper balancing.
