3.) Carefully slide the face plate and bushing/seal assembly over the
actuator rod end, while guiding the tie rods through the holes in
the rear end cap of the actuator. The seal is a tight fit on the rod
end. Take care not to damage the seal on the threads of the
extending rod. Standard Tritex rods have a chamfer to provide
a lead in for replacement of the seal and bushing. Be sure that
the faceplate seats completely and squarely on the front of the
actuator. The inner surface of the faceplate provides the pre-
loading for the bearings, and it is important that it is properly
seated.
Units with a Front Flange
Replace the faceplate as described above. Remount front flange by
sliding tie rods through the holes in the faceplate and through the holes
in the rear end cap. Pilot the flange on the pilot diameter located on the
front of the faceplate.
4.) Replace the rear tie rod washers and nuts and tighten to the
proper torque. Tighten the nuts simultaneously by partially
tightening each in an opposing corner pattern until each is
torqued to the rated value as follows.
Tritex 60:
30 lbf-in (2.5 lbf-ft, 3.39 N-m)
Tritex 75 & 90:
90 lbf-in (7.5 lbf-ft, 10.16 N-m)
Tritex 115:
240 lbf-in (20 lbf-ft, 27.12 N-m)
5.) 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.
