Confirm the correct replacement using the operator’s parts list or the designation printed on the original belt. Width, profile, and length must all match the equipment requirements.
Inspect the old belt for cracks, fraying, glazing, stretching, and uneven wear. Check the pulley grooves, alignment, and adjustment mechanism before fitting the replacement. Persistent slipping can indicate an alignment, tension, or pulley problem.
Disconnect and lock out operator power before accessing the drive. Install and tension the belt according to the manufacturer’s service instructions. Excessive tension can unnecessarily load bearings and other drive components.
Reinstall all protective guards before testing the operator.
Order this belt when your equipment specifies a 4L-profile V-belt measuring 1/2" x 39".
