Tensioning &
Replacing V-Belts
V-belts stretch and wear with use, so it is impor-
tant that tension is routinely checked and adjusted
as needed. Improperly tensioned V-belts will slip
or poorly transmit power from the motor. We rec-
ommend checking the tension on a monthly basis
to ensure optimal power transmission. Replace
the V-belt if it becomes cracked, frayed, or glazed.
Keep belts and pulleys clear of exposure to oil,
grease, or cutting fluids that will cause them to
slip.

The V-belt is correctly tensioned when there
is approximately
1
⁄
8
" deflection when pushed
with moderate pressure between the pulleys,
as shown in
Figure 120.
—If there is more than

tension until it is correct.

Replacing V-Belts
1. DISCONNECT MACHINE FROM POWER!
2. Open end cover.
3. Loosen tensioner bolt (see Figure 119) to
relieve tension on V-belt.
4. Carefully roll V-belt off of pulleys.
5. Install new V-belt, then tension as described
in
Tensioning V-Belts.
