V-Belt Tension &
Replacement
After initial break in, the V-belts slightly stretch
and seat into the pulley. It is important to check
and adjust them to compensate for this initial
wear. Check the tension thereafter on a monthly
basis. If the belts become excessively worn or
damaged, replace them as a matched set.

Tensioning V-Belts

1. DISCONNECT LATHE FROM POWER!
2. Remove the end gear cover.
3. Loosen the motor mount hex bolts (see
Figure 124).
Note: It may be more convenient to access
the motor mount hex nuts if you first remove
the rear splash guard.

4.
Push down on the motor and re-tighten the
mounting hex bolts.

5. Check the belt tension: Each belt is correctly
tensioned when there is approximately
deflection when it is pushed with moderate
pressure, as shown in Figure 125.
