4.) If your actuator has an external anti-rotate mechanism, slide the
rod or rods of the anti-rotate mechanism through the front flange
and into the guide bushing or bushings mounted to the rear of
the flange. Position the extending rod so that the wrench flats are
parallel to the long side of the flange. Slide the cross member
assembly of the anti-rotate mechanism over the end of the rod
and onto the wrench flats. Tighten the two screws that clamp the
assembly to the actuator rod.
Maintenance Procedures for Complete Re-Greasing
Disassembly
Refer to the exploded view on the following page.
1.) Remove the actuator assembly from the machine by
disconnecting the cables, main rod coupling and actuator
mounting bolts or fasteners.
2.) If your unit does not have an external anti rotate assembly, skip
this step. Loosen the two machine screws that clamp the anti-
rotate cross member to the actuator output rod. Slide the anti-
rotate mechanism forward and off the actuator.
3.) Remove the rear tie rod nuts from the back of the actuator.
The end cap houses the Tritex drive and control. Extreme
care should be taken when removing the tie rod nuts or tie
rods so as not to twist or pull on the drive section of the actuator.
Do not disconnect the wiring between the drive and the actuator.
4.) If your actuator does not have a front flange, skip this
step. Slide the front flange forward and off the actuator.
The tie rods will remain attached to the front flange.
5.) When the face plate is removed, the thrust bearing and
the open end of the roller screw internally threaded
cylinder (ITC) are visible. The roller screw can be
removed by turning it counter clockwise and threading it
out of the cylinder. It may be necessary to keep the roller
screw cylinder from turning to remove the screw.
