Installation & Adjustment Procedures
General Instructions for Threaded Clevises
When threaded clevises are specified, one is generally attached to the adjustable arm, and two
more to the center phase switch arm (refer to the plan view of the operating mechanism drawing
and the illustration below).
Operating mechanism adjustments consist mainly of incremental lengthenings and/or
shortenings of the pipe that connect the switch arms together. To make these adjustments,
simply loosen both jam nuts “A” and screw the stud in or out as required. Be sure to retighten
both jam nuts securely.
Be sure the initial setting is correct, and do not
adjust beyond the maximum allowable
dimension. If adjustment beyond the maximum
allowable dimension is needed loosen the U-
bolts on the outboard phase clevis and
reposition the pipe toward the center phase.
Initial dimension for ¾” stud is 11/16”; 1” stud is
½”.
Maximum allowable for ¾” stud is 1-3/16”.
Maximum allowable for 1” stud is 1”.
Do not screw the stud out of the clevises. This could cause
the pipe to fall, resulting in serious injury to personnel below.
