Installation & Adjustment Procedures
Operating Mechanism
Figure 12: Typical Operating Mechanism
1. Lay out all Operating Mechanism parts and check them against the Op-Mech drawing bill-of-
materials.
2. To ensure that the bearing stops do not interfere with switch adjustments, loosen all open/close
bearing stops, and slide them out of the way.
3. Refer to the Operating Mechanism drawing, and install all mounting brackets, bearings,
bushings, pipe clevises, switch operating device, adjustable arm, reach rod, and other
necessary components. Refer to Figure 12 .
4. While installing the pipes and clevises that have piercing bolts/set screws, do not pierce the
pipe until instructed. Tighten the piercing bolts such that they grip the pipe until all adjustments
are made.
The pipe collar (above the vertical bearing) must support the entire weight of the
vertical operating pipe. To prevent unnecessary component damage,
do not allow
the pipe to rest on the switch operating device. Refer to Figure 13 .
