Mounting
Crank Arm Kit for MEP-4000 Series Actuators
HLO-4001
Installation Guide
1. From the MEP-4xxx actuator, remove and discard
the V-bolt.
2. Assemble and install the kit and actuator as
shown in the diagram below.
NOTE: In general, position both the ball joints
as close to the end of the crank arms as is
feasible for the application. Positioning a
ball joint in the slot closer to the shaft will
change the torque, rotation speed, and/or
angle of rotation—which may be useful for
some applications.

Ball Joints
NOTE: Check for potential issues such as binding
of the linkage or damage caused by the
actuator still rotating when the damper (or
other application) is already closed.
NOTE: See the Accessories section for an auxiliary
crank arm if the damper or other equipment does not have one already installed.
NOTE: For much more information about installing
MEP-4xxx actuators, see the MEP-4xxx
Applications Guide on the KMC web site
(www.kmccontrols.com) as well as the

Maintenance

lubrication of the ball joints may be necessary.
