• With the motor now applying no tension to the belt, remove the belt. Check pulleys for
signs of wear or damage. Damage to the pulley guard can cause damage to the
pulleys, and this can cause damage to the belt. Make sure pulleys are aligned as well
to prevent damage to the sides of the pulley. Check to make sure motor shaft is not
contacting the side plate slot as well.
• With the belt off and pulleys exposed, check to make sure the pulleys are fixed tightly to
their shafts, via two set screws per pulley.
• Feed the belt back over the pulleys, pulling the motor back to allow for the belt to slip
over the drive pulley. With belt over both pulleys, apply pressure to the motor to create
belt tension. Belt should be tight, but not stretched.
• Holding tension on the belt, tighten the four bolts affixing the motor to the side plate.
• It is now possible to apply power to the machine and test the roller jog function. Care
must be taken to keep hands and fingers out of the belt line! Belts should not slip during
operation, and pulleys should not slip on the roller or motor shaft. If slip is detected, the
pulleys will need to have shaft set screws tightened.
• Once satisfactory, the guard should be reattached.
Drive Motor Replacement
Drive motors should last years if spring tension is adequate but not excessive. Replacement
drive motors can be purchased from TRC Industries wired and ready to install.
To replace a drive motor:
• Disconnect the machine from power. Allow machine to cool if necessary to avoid
contact with hot parts.
• On the infeed side of the machine, remove the two jack screws on either side of the
DB15 connection, circled in the photo below. This may require tilting the machine up on
the outfeed side of the machine to access the inside of the machine, as some of these
connectors use jack screws as well as a nut.
• With the jack screws removed, push the DB15 connector back into the body of the
machine.
