Installation Instructions – 3000 and 7000 Lathes

Discard the pin supplied with
the new pulley. The pin has no
function on the 3000 or 7000

lathe and may damage the lathe if installed.

1. Remove the v-belt and discard.

2. Back the set screws fully out of the v-belt pulleys.

3. Remove and discard the old pulleys.

4. Install the new pulleys using the set screws provided.

NOTE: On older lathes without the drive shaft key, the
pulley set screws must engage the 2 recesses in the
pulley shaft to properly position the pulley for correct v­belt alignment.

5. Align the motor pulley to the wormshaft pulley using
a straight edge.

6. Install the new v-belt on the pulleys.

7. Poly V-Belt Tension Adjustment:

The poly v-belt should be adjusted to deflect 3/32”
with a 5 pound push on the belt. The ideal tension is
the lowest tension at which the belt will not slip
under the highest load.

Check and adjust as required.

8. Apply the decal provided to the top outside surface of
the belt cover.
