pulleys, and belt inside

ning or starts unexpect-
edly.
nect the lathe from power
before opening the left
side door.

installed in the top position, the 120t/127t in the
middle position, and the 50t installed in the bot-
tom position, as shown in Figure 60. this configu-
ration of gears will cover most feed rates and inch
threading. the 30t, 32t, and two 40t gears are
provided for additional feed rates and inch/metric
threading.

To configure the quick change gears:
1.
disConnECt lAthE FroM poWEr!
2.
Engage the feed gears so that the change
gears will not rotate in the following steps,
then open the left side door.
3.
loosen the pivot hex nut and move the
middle gears away from the bottom gear,
then re-tighten the hex nut to keep the pivot
assembly in place.
4.
loosen the hex nut that secures the middle
gears and lower them away from the top
gear.
5.
to change either the top or bottom gears:
a. remove the cap screw and flat washer
that secures the gear, then the gear.
Note: Take care not to misplace the key
from the gear shaft.
b. Clean away debris and grime from the
gear and apply a light coat of machine oil
to protect it from rust before you store it.
c. repeat Step b for the replacement gear,
then align it with the key and insert it on
the gear shaft.
Note: When cutting metric threads, the
bottom gear must mesh with the 120T
gear of the middle gears. In order to do
this, you need to install the bottom gear
with the raised hub facing in toward the
lathe.
d. re-install the flat washer and cap screw.
