ADJUSTMENTS
Changing the belt requires that the headstock spindle be
removed, or half removed, from the headstock casting.
Then the new belt can be slipped over the spindle and
down inside of the headstock to the motor pulley.
1. Unplug the lathe from the power source and remove any
installed spur center or faceplate from the spindle.
2. Open the 2 Belt Doors
to gain access to the belt and
pulleys that are inside of the headstock. Figure 40, A & B.
3. Pull the Belt Tensioning Handle forward, away from the
motor. FIG. 41. (See Page 18, Figures 32 & 33).
4. Push the Tensioning Handle down, FIG. 41, to loosen the
tension on the Poly-V-Belt, and then secure the handle in
place by pushing the handle back towards the motor. The
belt can now be moved off of the 2 pulleys.
NOTE:
If the
belt is not to be saved, the old belt can be cut off at this time.
