spinner motor, pulleys, and belt.

motor pulleys by swinging the motor towards
the spinner pulley.

Disconnect the wire harness at the spade
connectors. Remove the two #10-32 locknuts
and washers that attach the motor to the base
plate.

the motor base plate.
6. Reinstall the new motor with the pulley
attached using two #10-32 locknuts and
washers. Reconnect the harness to the motor.

it moves freely. Check for looseness in the
shaft bearings. Repair as needed. Grease both
upper and lower shaft bearings.

and shaft pulleys. Con fi rm that the pulleys are
aligned with each other and that the belt is
running true. If adjustment is needed, loosen
the set screw on the motor pulley and adjust
the pulley up or down as required. Retighten
the set screw.

motor.
