out of its position.
4. Remove the pulley and four standoffs from the
old motor, and install on the new motor.

inside of the machine. Also be sure the belt is
over the pulley.
6. Reinstall the screws into the motor standoffs
through the slots in the cradle side plate.
Before tightening into position, be sure to set
the belt tension to a satisfactory level. The
center of belt span should displace about 1/16
th
of an inch when pressed with one finger
perpendicular to the belt travel (Refer to
“Checking Belt Tension” in Section 2 Machine
Adjustments for a more detailed explanation).
7. Replace all guards removed in the previous
steps.
