MK-3100 Series Typical Mounting
Accessories Required for Mounting Per Figure 5
1 — AM-113 Crank arm.
1 — AM-122-0-0-2 or AM-132-0-0-2 ball joint.
1 — AM-125 link rod 5/16-inch x 20 inches.
To mount proceed as follows. Refer to Figure 5.
1. Measure a minimum of 8 inches from damper shaft in the
direction of actuator location.
2. Hold actuator up to duct with actuator shaft approximately
1-1/2 inches above (N.C.) or below (N.O.) damper shaft
and mark mounting holes.
3. With drill or punch, pierce holes marked in Step 2.
4. Mount actuator to duct.
5. Attach ball joint to crank arm at approximately 2-1/2
inches from center of shaft hole.
6. Attach crank arm to damper shaft at approximately 45
angle, from vertical, toward actuator with damper in the
normal actuator retracted position.
7. Connect actuator ball joint to crank arm ball joint with
5/16-inch diameter rod. Cut off excess rod.
8. Refer to Checkout.

shaf
t, with the actuator rotary shaft approximately in line
with the damper shaft.
2. Hold actuator up to duct and mark mounting holes.
3. With drill or punch, pierce holes marked in Step 2.
4. Mount actuator to duct.
5. Attach crank arm to actuator shaft at approximately 45
angle.
6. Attach ball joint to crank at approximately 2-1/2 inches
from center of shaft hole.
7. Attach crank arm to damper shaft an approximately 45
angle, from vertical, toward actuator with damper in the
normal actuator retracted position.
8. Attach ball joint to crank arm at approximately 2-1/2
inches from center of shaft.
9. Connect actuator ball joint to crank arm ball joint with
5-1/6-inch diameter rod. Cut off excess rod.
10. Refer to Checkout.
