V-Belt Service
Checking V-Belt
To ensure optimum power transmission from the
motor to the blade, the V-belt must be in good
condition and properly tensioned. The belt should
be free of cracks, fraying, and wear. Belt tension
and condition should be checked at least every
3 months—more often if the bandsaw is used
daily.
To check V-belt tension:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover.
3. Check the condition of the V-belt. If the V-belt
is cracked, frayed, or glazed, replace it.
4. Check the V-belt tension by applying mod-
erate pressure between the pulleys (see
Figure 91). If deflection is not approximately
3
⁄4", re-tension the V-belt following the same
steps you normally use when changing blade
speeds (refer to Blade Speed on Page 52 if
necessary).

the bearing shaft.

5. Slip the old V-belt off of the wheel pulley and
install the new V-belt in its place.
6. Properly tension the V-belt and re-tighten the
motor mount cap screws.
7. Re-install the lower wheel back and secure it
with the wheel mount bolt.
8. Re-install the blade and close the wheel cov-
ers.

4. Loosen the motor mount cap screws shown

Replacing V-Belt
To replace the V-belt, you must remove the blade
and the lower wheel. After re-installation, you
must properly re-tension the V-belt.
