How to Remove the Tower Lift
Cylinder
The tower lift cylinder raises and lowers the tower
assembly. The tower lift cylinder is equipped with
counterbalance valves to prevent movement in the
event of a hydraulic line failure.
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 Tag, disconnect and plug the tower lift 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.
2 Support both ends of the cylinder with a
suitable device to prevent it from falling.
3 Remove the pin retaining fasteners from both
the rod end and barrel-end pivot pins.
4 Place a rod through the pins and twist to
remove. Guide the cylinder out the pivot end of
the tower and carefully remove the cylinder
from the machine.
Component damage hazard.
Cables and hoses can be
damaged if the cylinder is
dragged across them.
