Procedures
The two front end motors are individual components that attach directly to the front end gearboxes and are
used to run the table and sweep. NEVER attempt to operate a motor when it is in a partially disassembled
state or when it has been removed from its gearbox housing!
2.3.1
Servicing the Front End Motor, Brake, and Encoder
Wear eye protection and a dust mask when using compressed air to blow out
components.
Perform this maintenance activity every 100,000 frames.
1.
Run the sweep(s) to the 1st guard position.
2.
Remove power from the pinspotters. Follow the appropriate Lockout/Tag Out procedures.
3.
Loosen the screws holding the crossbeam covers to the crossbeam and remove the covers.
4.
Cut and remove the plastic wire tie (if still attached) holding the brake and encoder wire to the motor
housing.
5.
Remove the four Phillips head screws attaching the motor enclosure to the top of the motor.
6.
Carefully lift the motor enclosure with brake from the motor top. Be careful of the motor plug wires,
allowing the motor enclosure to hang.
7.
Using compressed air, blow the dust & dirt from the top of the motor and encoder.
8.
Holding the motor enclosure with brake in one hand, blow out the brake with compressed air.
9.
Inspect brake and encoder components and replace any damaged or excessively worn parts in
accordance with Sections 2.3.2 and 2.3.3.
10.
Reattach the motor enclosure with brake to the motor top by aligning the splines on the brake disc
with the splines on the brake hub. (Depressing the brake release will allow for brake disc movement,
that will ease the reattachment of the motor enclosure).
11.
Install the four Phillips head screws and secure the motor enclosure to the top of the motor.
12.
Check that the wires from the brake and encoder run through the grommet and into the crossbeam.
13.
Install the crossbeam covers and tighten the screws that secure them to the crossbeam.
14.
Install a new plastic wire tie around the brake and encoder wires routing it through the motor vents.
15.
Repeat this procedure for the other front end motor(s), as applicable.
16.
Restore power to the pinspotter.
17.
Run the sweep(s) to the Home position.
18.
Cycle the pinspotter and observe for correct operation.
