How to Remove the Secondary
Boom Extension Cylinder,
S-120 and S-125 Models
Bodily injury hazard. This
procedure requires specific repair
skills, lifting equipment and a
suitable workshop. Attempting this
procedure without these skills and
tools could result in death or
serious injury and significant
component damage. Dealer
service is strongly recommended.
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 Two,
Hydraulic
Hose and Fitting Torque
Specifications.
1 Raise the boom until the secondary boom
extension cylinder barrel-end pivot pin is above
the turntable covers.
2 Remove the secondary boom extend cylinder
cover retaining fasteners. Remove the covers.
Bodily injury hazard. Do not
operate the machine unless the
secondary extend cylinder covers
are properly installed. Operating
the machine with the covers
removed could result in death or
serious injury.
3 Tag, disconnect and plug the secondary boom
extension cylinder hydraulic hoses. Cap the
fittings on the cylinder.
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.
4 Support the secondary boom extension cylinder
with an overhead crane or other suitable lifing
device.
5 Remove the pin retaining fasteners from both
the rod-end and barrel-end pivot pins. Do not
remove the pins.
6 Protect the boom lift cylinder rod from damage.
7 Use a soft metal drift to remove both pivot pins.
8 Remove the secondary boom extension
cylinder from the machine while guiding the
barrel end of the cylinder out of the boom.
Crushing hazard. The secondary
boom extension cylinder may
become unbalanced and fall if it is
not properly supported when it is
removed from the machine.
Component damage hazard. The
boom lift cylinder rod can become
damaged if the barrel end of the
secondary boom extension
cylinder is allowed to come in
contact with it.
