There are 11 belts used in the AdvancedPunch Pro.
Drive Panel Steering
Sub Assembly
Five of the belts at the rear of the Frame have Tensioner Assemblies. It is
these five belts that should be checked.
Maintenance Schedule
Inspect the Timing Belt every 1000K cycles.
Procedure
Do the following to inspect the Timing Belts.
1. Inspect all timing belts for wear, missing teeth, frayed edges, and
cracks.
2. For replacement, see REP 2.21 Timing Belt Replacement
3. Check for proper deflection of belts.
The belts should be slightly loose with approximately 1/4” deflection

Belts that are too loose will not drive properly and belts that are too
tight can wear out prematurely or damage their driven components.
