Standard Rotary Mounting Procedure
(See Figure 15
)

The standard rotary mounting applies to valve/actua-
tor assemblies that do not have mounted volume tanks
or handwheels. The standard mounting uses a linkage
directly coupled to the valve shaft. This linkage has
been designed to allow for minimal misalignment
between the positioner and the actuator. The tools
required for the following procedure are:

1. Fasten spline lever adapter to splined lever using

two No. 6 x 0.50-inch self tapping screws.

2. Slide take-off arm assembly onto spline lever

adapter shaft. Insert screw with star washer
through take-off arm and add second star washer
and nut. Tighten nut with socket so arm is lightly
snug on shaft but still able to rotate. This will be
tightened after linkage is correctly oriented.

3. Attach follower arm to positioner feedback shaft

using the star washer and No. 10-32 nut.

NOTE: Arm will point up when feedback shaft is in
the free position.

1. Using four 0.25-20 x 0.50 L. bolts, fasten positioner

to universal bracket using appropriate hole pattern
(stamped on bracket).

2. Using a

0.50 L. bolts, attach bracket to actuator transfer
case pad. Leave these bolts slightly loose until final
adjustments are made.

3. Rotate take-off arm so the follower pin will slide into

its slot. Adjust bracket position noting the engage-
ment of the follower pin and the take-off arm slot.
The pin should extend approximately

tighten the bracketing bolts.

Orienting the Take-off Arm for Final Lock Down

Tube positioner to valve in the following manner:

1. OUTPUT 1 port of the manifold to the bottom side

of the Actuator.
