1. Remove the 2 hex head screws and the 2 slot head
screws holding the Motor to the Wire Drive Gearbox
assembly.
2. Remove existing Adapter Plate and Motor
Assembly.
3. Take the two long screws removed in step 1 and
screw one into each of the tapped holes located on
the face of fiber input helical gear. Insert the screws
through the full thickness of the gear, and using a
screwdriver wedged between the screws to prevent
rotation, remove the hex nut that holds the gear to
the shaft. Remove plain washer.
4. Pull the gear from the shaft using the screws as a
pulling device.
5. Be certain woodruff key is properly located on the
shaft. Screw the adapter plate and motor assembly
mounting screws into the new fiber input helical
gear from the stenciled side and place the gear on
the shaft. Replace plain washer, tighten the hex
nut, and remove the adapter plate and motor
assembly mounting screws from the gear.
6. Support the pinion properly and, with the proper
size punch, drive the roll pin that holds the pinion
out of the shaft. Pull the pinion off. Remove the
Ring Magnet from the pinion gear and snap it onto
the new pinion gear. Before installing the new pin-
ion gear with the Ring Magnet onto the motor shaft,
ensure that the flat washer is located at the bottom
of the shaft. Install the new pinion and replace the
roll pin.
7. Cover the teeth of the motor pinion and the input
gear with a non-fluid molydisulfide type grease such
as Non-Fluid Oil Corporation’s A-29 Special/MS
Lubricant. This grease can be scooped from the
cavity of the gear case.
8. Reassemble the motor on the gearbox; make sure
the gears mesh properly and the adapter plate
locating bead is in its cavity. Replace and tighten
the four screws removed in step 1.
9. See the power source manual on how to config-
ure the power source DIP switches for the new
gear ratio.
