Disassembly

To disassemble the clutch, support the clutch on
the back of the field assembly between the coil
leadwires and the center mounting sleeve. Using a
rod that fits inside the inner race of the bearing,
press down on the mounting sleeve until the
mounting sleeve has cleared the armature
bearings. Remove the armature assembly and the
sleeve that separates the bearings. Continue
pressing the mounting sleeve through the rotor
bearings and the field support.

Assembly

Inspect all of the bearings for smooth rotation of
the inner race. Clean any remaining Loctite from
O.D. of the mounting sleeve, the I.D. of the field
support and the I.D. of the bearing spacer.
Support the flanged end of the mounting sleeve
and press the field assembly onto the mounting
sleeve. Next, press the rotor assembly onto the
mounting sleeve. Then place the bearing spacer
onto the mounting sleeve. Finally, press the
armature assembly onto the mounting sleeve and
press the entire clutch assembly together. There
should not be a gap between the mounting sleeve
flange and the field support. Rotate both the
armature and the rotor and check for free and
independent rotation. If the parts do not spin freely
or there is any drag between the rotor and the
armature disassemble the clutch and examine all
of the parts for signs of damage.
