Inspect each belt for wear,
fraying or other damage. The
belts should have equal
amounts of tension; you
should be able to deflect the
belts no more than ~1/4”
when pushing firmly inward
as shown in the photo.
Also inspect both large and
small pulleys, and verify that
they are properly aligned; the
black drive belt must be
parallel to the motor mounting
plate, as shown.
Misalignment of these pulleys
can result in failure of the
pulley side plate and/or damage to the belt.
