Gear change
Note
: The 120/127, 26, and 52 tooth gears are
installed by the manufacturer in the end gear
compartment. This combination will cover most inch
feeds and threads under normal circumstances. The
additional gears found in the toolbox are used for
some metric threads and feeds.
To replace gears:
1. Turn off power at main switch.
2. Remove end cover.
3. Loosen hex nut (S, Figure 11-8) and move
quadrant out of the way.
4. Loosen socket head cap screw (T) and remove
gear(s). Select replacement gears to match
data on feed and thread chart. Thoroughly
clean new gears before installing.
5. Move quadrant so that large gear meshes with
the smaller gears, and tighten nut (S) to secure
in place. Note: Make sure there is backlash of
0.002” – 0.003” between gears. Setting the
gears too tight will cause excessive noise and
wear.
6. Install end cover.
