To lubricate the feed direction gears:
1. DISCONNECT LATHE FROM POWER!
2. Back out the tensioning thumb screw (see
Figure 81) all the way, then push the top
large end pulley toward the back of the lathe
to release the tension on the attached timing
belt.
4. Loosen the pivot lock bolt shown in
Figure 81, then turn the spindle
counterclockwise by hand as you apply
pressure to the direction gear pivot bracket
until both grease fittings are accessible for
lubrication.
5. Add lubricant and wipe of any excess
lubricant.
6. Rotate the direction gear pivot bracket so
that the direction gears correctly mesh
with the spindle shaft gear for your next
operation, then re-tighten the pivot bolt.
7. Apply upward and forward pressure to the
top end pulley to tension the timing belt as
you re-tighten the tensioning thumb screw to
secure it in place.
Important: Leave a slight amount of slack in the
timing belt. Adjusting the tension too tightly
will cause excessive wear and stretching.
Adjusting the tension too loosely could cause
the timing belt to slip during operation.
8. Close the end cover before re-connecting the
lathe to power.
