NOTE
STEPS AND DIMENSIONS SHOWN
ARE FOR MST MODELS. SEE APPENDIX
A-D FOR OTHER MODELS.
1.
Reconfirm the centerline location for the OV (Figure 11).
2.
While holding the OV in place, use a pencil and mark the
center of all four anchoring holes in the base of the OV
(Figure 12).
3.
Using a ⅝" concrete drill bit, drill four anchor holes, 3" in
depth, at the center of each marked location in Step 2.
NOTES
The anchor hole(s) must be clean before installing the
anchor bolt(s). If the hole(s) are not clear of debris, the
anchor bolt(s) may not tighten correctly.
If desired, conduit stub may be marked and installed at this
time. Refer to the "Electrical Wiring" section.
4.
Insert anchors into the drilled holes. The threaded end of the
anchor must be inserted into the hole first. Use a hammer to
tap the anchor into place, if needed. Ensure that the anchors
are flush with the concrete floor.
5.
Place the OV back over the anchor holes and anchor it with
four ⅜" x 2½" anchor bolts and flat washers (Figure 13).
6.
Once the OV has been anchored,
use a socket wrench and 9/16"
socket to tighten the anchor bolts
(Figure 14).
7.
Confirm OV is level and plumb.
Shim as needed.

NOTE
Prior to installing, liberally apply a coating of grease to the shaft, top of the bearing, sides of the bottom
bearing plate and inside the bottom bearing plate (layer ¼" to ½" in thickness). Applying grease as
indicated will help protect against moisture and foreign matter penetrating the bearing area.
1.
Attach the bottom bearing, collar facing up, to the
lower end of the roto (Figure 15) by sliding the
bottom bearing onto the mounting shaft
(Figure 15A).
