Bonding the Drive Belt Pulley
In 2019 Bend-Tech began using bonding compound to help secure the Drive Belt Pulley to
the Drive Motor. It is recommended that Owners having Drive Belt issues on earlier machines
remove the Drive Belt Pulley and reassemble with bonding compound to secure the Drive Belt
Pulley.
1.
the Trolley Cover.
2. Remove the red button on the switch by unscrewing it counterclockwise. Remove the
chrome plastic collar on the switch by unscrewing it counterclockwise. Remove the yellow
label ring. Remove the E-stop switch from the Trolley Cover. Re-attach the yellow label ring,
chrome collar and red button. Set the e-stop switch on the Trolley, out of the way.
3.
Housing to the Trolley and Front Plate. Remove the Chuck Housing and set aside.
4. Purchase Loctite 638 Retaining Compound
5. Loctite 638 Retaining Compound can tolerate a certain level of contaminants upon
application. However, for best results, Bend-Tech recommends cleaning the motor shaft
and Drive Belt Pulley with Loctite Cleaning Solvent and allow to dry before applying the
Retaining Compound.
6. Place Retaining Compound on the motor shaft and set the pulley at .375 in. from the face
of the motor gear box mount.
7. Apply Loctite 242 to the Drive Belt Pulley set screw and thread it into the pulley. Tighten the
set screw down to the shaft and give another ¼ turn. Ensure Drive Belt Pulley is .375 in.
from the face of the motor gear box mount.
8. Allow the Loctite 638 Retaining Compound to cure for 24-hours before using the machine.
9. Position the Trolley at the center of the Rail. Route the Drive Belt around the idler pulleys
and the Drive Belt Pulley.
10. Perform the Drive Belt tensioning procedure. Set the Drive Belt tension at 120. Increase
tension (up to, but not more than, 140) if the Drive Belt rides too far to the outside of the
Drive Belt Pulley.
