1. Slide the entire actuator assembly onto the
shaft. If necessary on Optimux actuator
designs with clamping lever arm design,
wedge the splined lever arm apart to loosen
it on the shaft splines. For full rotation of the
disc, marks provided on the end of the shaft
and on the lever arm should be aligned.
2. Bolt the actuator yoke to the valve body. Be
certain the stroke indicator plate is
positioned properly to accurately indicate
the valve's rotation.
3. Position the actuator lever arm on the shaft
so the actuator stem is centered in the
transfer case. Firmly tighten the linkage
bolt, on clamping lever arm actuators.
CAUTION:
On clamping lever-
arm actuators, do not apply air
to the actuator without
the cover plate installed;
otherwise, the unsupported
shaft may sustain damage.
4. Adjust the actuator stroke stop bolts until
the disc is parallel to the seat surface, but
not resting on body disk stop.
CAUTION:
Actuator stroke stop
bolts must be properly
adjusted, to prevent the valve
disc from overstroking. If
incorrectly adjusted the valve
shaft may be twisted or sheared
off.
5. Install valve in line as outlined in
Installation
