Pulley alignment
Warning
Before running the machines make sure machine areas are
clear, all equipment has been removed and all guards are
back in place.
The machines are now ready to be run.
The final step is to run the machines for a couple of hours
allowing the belts to stretch and seat themselves properly in the
grooves. The belt tensions must be checked to conform with the
recommended values. Now run the machines at least 72 hours.
The tension on the belts should be checked and tightened or
slackened to correspond to the manufacturer's recommended
force values for used belts.
Pulley alignment tolerance
Normal tolerance for belt drives is 0.5°. Most major belt and
pulley manufacturers specify this value. Better tolerances can be
achieved if the alignment procedure is carefully followed. The
table below converts the tolerance from degrees into offset in mm
per 100 mm (mils per inch).

Note that the values between 0.1° and 0.5° fall within recom-
