ADJUSTMENTS
To change the belt, the whole spindle shaft needs to be
shifted right, out of the headstock, towards the tailstock.
This will allow the new belt to be slipped over the spindle
and onto the spindle pulley. Then the whole spindle shaft
assembly can be re-installed so turning can be resumed.
1. Unplug the lathe from the power source.
2. Remove any accessories from the spindle - spur center,
face plate, chuck, etc.
3. Open the top Headstock Cover (#35, FIG. 10, A) and the
left side, Bed Cover Plate Door (#8, B) to gain access to
the belt and pulleys that are inside of the headstock.
4. Loosen the motor mount Locking Handle (#21, C).
5. Lift the Motor Connecting Plate Handle (#19, D) to
loosen the tension on the Poly V-Belt (#16). The belt can
now be removed from the lower Motor Pulley (#14, E).
6. Loosen the two (2) Set Screws (#40) that attach the
Hand Wheel (#41, E) to the spindle, and remove the Hand
Wheel.
7. Remove the two countersunk Phillips Screws (#33B)
that hold the RPM Reader and Support Bracket assem-
blies (#49, 48, 48A-F), which are located under the Spindle
Pulley’s Segmented Plate (#53, G). This will drop the RPM
Reader inside of the headstock and safely away from the
spindle pulley. FIG. 11. See Parts Diagram on page 18.
8. Remove the Set Screws (#51, H) that attach the Spindle
Pulley to the spindle. The pulley should now be loose on
the spindle.
NOTE:
There are two (2) set screws, one on
top of the other, in both of the two (2) threaded holes. This
stacking keeps the set screws from loosening during use.
9. Remove the Retaining C-Clip (#39) that is on the out-
side, left end of the spindle where the hand wheel was.
10. Carefully knock the spindle, towards the tailstock. Use
a block of wood against the spindle end to prevent any
damage when it is hit with a mallet/hammer. The spindle
pulley, now loose, will slide along the spindle.
11. Remove the old belt, if present, and install the new belt
over the spindle pulley. Return the pulley back onto the
spindle, and re-install the spindle back into the headstock
casting. As in step 10, carefully knock the spindle and bear-
ings into place with a block of wood and mallet.
12. Secure the spindle pulley in place on the spindle with
the set screws. Make sure that the set screws engage back
onto the flat sections on the spindle to eliminate slippage.

13. Re-install the RPM Reader & Support Bracket that
were unscrewed in step 7. The Reader’s elements are ‘U’
shaped and must be positioned so that the Segmented
Plate is in the middle of the two Reader’s elements.
You will have to reach up inside the headstock to position
the bracket to take the two screws. HINT: Use an awl, stiff
wire or toothpick to help align the bracket’s threaded holes
with the countersunk holes in the headstock. This will make
re-fastening the screws easier.
14. Re-assemble the remaining headstock parts by revers-
ing the procedure previously described.
