V-Belt Tension &
Replacement
V-Belts stretch and wear with use, so check the
tension on a monthly basis to ensure optimal
power transmission. Replace the V-belts if they
become cracked, frayed, or glazed.
On the Model G0602, the low range V-belt ten-
sion is controlled by a tensioner between the
secondary drive pulley (B) and spindle (C) pulley.
The high range V-belt between the spindle (C)
and motor (A) pulleys is tensioned by the motor.
On the Model G0752, V-belt tension is controlled
by a tensioner between the spindle and motor
pulleys.

Tensioning V-Belt
To tension the Model G0602 low range V-belt
or Model G0752 V-belt:
1. DISCONNECT LATHE FROM POWER!
2. Open the change gear cover.
3. Loosen the tensioner lock nut (Model G0602)
or tensioner lock bolt (Model G0752) shown
in Figures 93–94.
4. Push the tensioner against the V-belt to ten-
sion it, then secure the tensioner.
The V-belt is correctly tensioned when there
is approximately
1
⁄4" deflection when it is
pushed with moderate pressure, as shown in
Figure 95.
Figure 94. Model G0752 tensioner and lock bolt.
—If there is more than
1
⁄4" deflection when the
V-belt is pushed with moderate pressure,
loosen the tensioner, adjust it so the ten-
sion is correct, then secure the tensioner.
5. Secure the change gear cover.
