1. Turn belt with tabs to the inside before installing.
2. Determine direction of drive rotation.
3. Align belt directional arrow with drive rotation.
4. Fit belt in nearest groove of smaller sheave.
5. Roll belt onto larger sheave, turning the drive slowly. Belt
may seem very tight; this is okay. DO NOT jog motor.
6. Check to see all tabs are still in their correct position and
are not twisted out of alignment.
7. For multiple belt drives, work belt from groove to groove.
On particularly wide drives, it may be easier to install
half the belts from the inboard side and half from the
outboard. Note: 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.
1.
Set motor to mid-position of adjustment range and
mark base clearly.
2.
Determine required belt length as in “Measuring
Belt
Length.”
3.
Push motor forward to minimum center distance.
4.
Install belts as in “Installation.”
5.
Pull motor back to previously marked mid-position.

Belts require the maintenance of correct drive tension to
operate effi ciently. 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. Subsequently,
belt tension should be checked periodically and adjusted
when necessary.
