Actuator Installation Using Anti-Rotation
Bolts
Tools Needed: A 7/16” open wrench or torque wrench
with 7/16” crowfoot wrench adapter.
Part #: The parts come with the actuator. Retrot kit #
is 25972R (Includes 4 sets of bolts, washers, retainers &
E-clips).
1. Install the Grooved Bolt and Washer and torque
them to 6 lb-ft. See gure 5-48 (a).
NOTE
It may be necessary to adjust the bolt position so
that one of the bolt edges is parallel to line A and
B, then the retainer will drop-on easily. If required,
tighten bolt further for this alignment.

2. Position Locking Retainer over Grooved Bolt, with
the shallow curved edge toward the center of the
command shaft housing. See gure 5-48 (b).
NOTE
The locking retainer hex hole is offset 3° so ipping it
over gives it new positioning.
3. Push E-Clip into Grooved Bolt Head. Once E-clip is
on make sure it rotates back and forth freely. This
will ensure E-Clip is completely seated. See gure
5-48 (c).
