B. Assembling the Sheave, Pulley, or
Sprocket and Clutch
1. Install the key in the outer diameter of
the Electro-Clutch hub. (A special key is
furnished.)
2. Mount a standard sheave, pulley, or sprocket
to the Electro-Clutch with a standard tapered
bushing. Note: Only standard tapered
bushings are recommended for this
purpose. A straight bore drive component
mounted with set screws will damage the
Electro-Clutch bearings.
3. Install the belt on the sheave, pulley, or
sprocket. Keep the belt tensions within the
recommendation of the sheave or pulley
manufacturer.
C. Electrical Installation
Each Warner Electric control is furnished with a
wiring diagram showing the correct electrical
connections between the control and the clutch.
Two straps are provided on the clutch torque
arm to hold the clutch lead wires in place.
(Service Manual P-239 contains complete
information on all standard power supplies.)
D. Replacing Worn Parts
The two main wearing parts, the armature and
the rotor, may be easily replaced. For stub shaft
mounted applications, these parts can be
replaced without removing the Electro-Clutch
from the shaft. The rotor and the armature usu-
ally wear at the same rate and should be
replaced together.
1. Remove the mounting screws and lockwash-
ers that hold the armature carrier assembly to
the sleeve. (Figure 2)

2. Remove the rotor mounting screws.
3. Insert two of the rotor screws in the removal
holes of the rotor to back the rotor off the
bearing. (Figure 3)

4. Install the new rotor on the clutch assembly.
Dip the mounting screws in Loctite ® before
reinserting them.
5. Install the new armature assembly. Dip the
mounting screws in Loctite before reinserting
them.
