Maintenance

Replacing V-Belt: The pulley system allows the lathe to operate at variable speeds and keeps the V-belt properly tensioned. If the V-belt shows signs of cracking, splitting, or any other damage, replace it to ensure optimum power transmission.

1. DISCONNECT LATHE FROM POWER! 2. Remove the V-belt safety cover from the back of the lathe. 3. Pull the motor pulley plates apart so that the V-belt slips down to the motor arbor, as shown in Figure 51. This will decrease the V-belt tension. 4. While keeping the tension off the V-belt, roll it off the spindle pulley and remove it. 5. Install the new V-belt by reversing Steps 3–4. 6. Re-install the V-belt safety cover before connecting the lathe to power.

Aligning the centers: 1. DISCONNECT LATHE FROM POWER! 2. Remove the tool rest from the bed. 3. Install the centers, then slide the tailstock up to the head so that the centers are facing each other, as illustrated in Figure 50. 4. Loosen the head lock lever, adjust the head position so that center tips touch, then retighten the lock lever to hold the head in place.

Note: If the spur center is lower than the live center, use shims under the head. If the live center is lower, use shims under the tailstock.
