Strike each end of worm shaft sharply with a soft face
hammer to seat bearing properly. Recheck flange bolts
for tightness. Worm should turn freely with minimum drag
and end play. If too much end play is present, remove
shims as required. If worm does not turn freely, add shims
as required.
7. Install top load bearing (2) or bearing cup on
worm gear (3),
8. Fill housing fully with grease.
9. Install shell cap (4) and screw down until tight.
Shell cap flange does not necessarily have to bear against
top of shell, there will usually be a gap. This will put a
slight drag on the worm. If worm is hard to turn, back off
slightly on the shell cap.
10. Lock base plate in place with set screws.
If new parts have been installed, it may be necessary to
respot holes for these screws.
11. Screw bottom pipe (16) into shell (1) (upright models)
or into shell cap (4) (inverted models).
12. Install guide bushing (17). Brush lifting screw (19) with
a light film of grease and install in actuator.
13. Operate unit to ensure proper functioning of all
components prior to reinstallation.
