Advanced Punch Service Manual
Maintenance Schedule
Inspect every 750K cycles.
Replace as needed.
Procedure
Inspect all timing belts for wear, missing teeth, frayed edges, and cracks. The belts
should be slightly loose with approximately 1/4" deflection [1]. Belts that are too
loose will not drive properly and belts that are too tight can wear out prematurely
or damage their driven components.
To replace belts:
1. Loosen the screws of the 3 belt idlers [1].
Installation Note: When setting the belt tension, adjust the belt idlers so that the
belt has approximately 1/4" of deflection.
