5.Raise the idler pulley shaft until you can replace the V-belt with a new one, then lower the shaft onto the bottom bracket.

Note: Make sure the bearings on either side of the pulley shaft are correctly positioned on the bracket.

6.Replace the bearing caps and re-tension the V-belt.

Spindle V-Belt

Proper tensioning of the spindle V-belt is auto- matically set when you push the belt tensioning lever back (see Figure 90).

To replace the spindle V-belt with a new one you must remove the spindle assembly from the lathe. This option is difficult and time consuming.

We recommend the alternative solution of just cutting the old V-belt to remove it, then replacing it with a Power Twist® V-Belt.

Power Twist® V-Belts

H9815—A 12" x 4'

H9816—3L 38" x 5'

H9817—B 58" x 6'

Perfect for lathes, table saws, bandsaws and other powered tools. Smooth running with less vibration than solid belts. Power Twist® V-Belts can be customized in minutes to any size—just add or remove sections to fit your needs. Carry a Power Twist® V-Belt in your vehicle for a fix any- where solution to broken fan belts.
