Alternative Installation Method
1. Set motor in mid position of adjustment range and
mark base clearly.
2. Determine required belt length as described in How
to Measure section.
3. Push motor forward to minimum center distance.
4. Install belts as in Installation section.
5. Pull motor back to previously marked mid position.
Retensioning
Like all high performance V-belts, PowerTwist Plus V-
belts require the maintenance of correct drive tension to
operate efficiently. Experience indicates that drive tension
should be checked after 24 hours running at full load. A
retension may be necessary depending on the severity of
the drive. Any initial belt stretch is then taken up. Subse-
quently, belt tension should be checked periodically and
adjusted when necessary.
IMPORTANT
With drive ratios around 1:1, it may be necessary to add
back one link to allow belts to be rolled on. This does not
apply if using Alternative Installation Method.
