Measure belt tension
by using a straight edge
and tension gauge as
shown above. Refer
to diagram below for
proper tension
specifications.
To tighten belt, slide
turbine away from the
motor. Before sliding
the turbine, the
silicone on the top of
the motordeck must be
cut and removed.
After removing the
silicone, loosen the
turbine hardware and
adjust the turbine
position as necessary.
Once the belt has been
properly tensioned,
secure the hardware
and re-seal the turbine
with silicone.
CAUTION: Motor deck will be heavy and will require a hoist to remove.
Before any maintenance
service is done, follow standard lock out and tag out procedures as well.
New 6-groove belts should be set to 6lbs at 3/16” of deflection. New 10-groove belts should be
set to 9lbs at 3/16” of deflection. Allow new belts to stretch by running in for several hours. After
run-in period, 6-groove belts should be between 4lbs to 5lbs, and 10-groove belts should be
