Installation Instructions
Electro-Clutch
A. Mounting the Electro-Clutch
1. Ideally, the Electro-Clutch should be mounted
on a through-shaft for firm support. In the
case of a stub shaft, the stub should be as
long as the clutch assembly, although for
moderate duty applications a shaft which is
2/3 or more the length of the assembly
normally provides adequate support.
2. Insert the key in the shaft. If the keyseat is
opened at one end of the shaft, prick punch
the shaft to prevent the key from working out.
3. Slide the assembled Electro-Clutch on the
shaft. (When the Electro-Clutch is mounted
on a stub shaft, the set collar end of the
clutch should be toward the support
bearings.) Tighten the setscrews in the set
collar. (Figure 1)

4. Secure the torque arm to the tab on the field
and rotor assembly. Secure the other end of
the torque arm to a solid base. Under no
circumstances should the torque arm be
pinned down so tightly that it preloads the
bearing. For more information on torque
tabs, see page 4.
