Re: Jet 1442 Question ()

When the reeves pulleys have excessive wear they will start to eat the belts quickly.
The range of speed selected which displays the noise is the area on the reeves pulleys
that have extensive wear causing the noise. The reeves pulleys are flexing back and forth
on the outside edge of the belt causing the noise and the excessive wear on the belt. The
belt usually shreds to pieces and the pulleys can fragment when the belt lets go. Any slop
in the reeves splines and the shaft hub clearance will slowly cause this problem. Regular
maintenance and cleaning of the shaft and reeves pulleys will extend the life. The die cast
pulleys have a rated life cycle and their is no getting around the issue. The old cast iron or
steel pulleys lasted a long time but were expensive to manufacture.
