A claw coupling with an elastic coupling ring is located between the motor and the gear. The
coupling ring consists of moisture and heat resistant polyurethane.

Remove the 4 fixing bolts on the motor base above the brake lever.
•
Mark the position of the handwheel in relation to the motor cover.
•
Lift the motor using a rope sling and eyebolts attached to the side of the motor until the
claw coupling is visible.
•
Atttention: Never use the handwheel to lift the motor!
•
Replace the elastic coupling ring; at the same time clean the claw coupling e.g. by blowing
out.

To replace the motor, put the handwheel in the marked position and carefully guide the
coupling claws into each other while lowering.
