General Instructions for Threaded Clevises
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.
Do not screw the stud out of the clevises. This could cause the
pipe to fall, resulting in serious injury to personnel below.
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”.
