                                                                                                    January 2020

Applications
The M9000-400 Jackshaft Linkage Kit is designed to simplify the installation of select Johnson Controls® actuators
onto dampers with jackshafts. The open-ended design enables the linkage to clamp onto a jackshaft without
requiring access to the ends of the jackshaft.
The maximum jackshaft diameter that can be accommodated is 1.05 in. (26.7 mm). A reversible metal clamp insert
accommodates 1/2 and 3/4 in. (13 and 19 mm) jackshafts.
For tight installation spaces, the actuator anti-rotation plate enables actuator installations to be rotated 90 degrees.
Use the M9000-400 Jackshaft Linkage Kit:
•     on a simple damper and jackshaft.
•     on a jackshaft that connects multiple sections of damper together.
•     to allow damper operation from either side of the HVAC equipment.
•     when dampers are recessed into walls or equipment and the side of the damper is not accessible for control
      shaft mounting.

    IMPORTANT: Do not apply actuators in excess of 90 lb·in (10 N·m) rated torque on a 1/2 in. (13 mm) jackshaft.

Installation
Choose an actuator from one of the series listed in Table 1. There is a torque reduction associated with use of the
M9000-400.

There are three basic locations to mount the kit:
•   Parallel to the damper inside air stream (Figure 15)
•   Perpendicular to the damper inside air stream (Figure 17)
•   Outside the air stream (no illustration available)
When mounting, check that there is at least 3 in. (76 mm) of space between the damper blade and the jackshaft.
Also check that the mounting location allows for the 4-3/4 in. (121 mm) width of the linkage.
To install the M9000-400 Jackshaft Linkage Kit:
1. Set the jackshaft clamp to the correct size for the jackshaft.

                                     Figure 1:      Setting the Jackshaft Clamp

2. Insert the retainer.
                                         Figure 2:       Inserting the Retainer

3. Remove two screws and adjust the anti-rotation bracket length to fit the type of actuator used. See Figure 3
   and Table 2.

9. With the linkage in place, secure the linkage to the damper frame with the anti-rotation L-bracket. Secure the
   adapter plate to the anti-rotation L-bracket with the flat-head screws. See Figure 9.
    Note: The anti-rotation L-bracket can rotate to any angle. If necessary, use the additional adapter plate for
    smaller bearings.
