The end gears, shown in Figure 121, should
always have a thin coat of heavy grease to
minimize corrosion, noise, and wear. Care must
be taken to avoid over-greasing because excess
grease may be flung onto the V-belts, which will
reduce optimal power transmission from the
motor.

Handling & Care
Make sure to clean and lubricate any gears you
install or swap. Unless you are very careful
during handling and storage, the coating of
grease on the gears will easily pickup dirt or
debris, which can then spread to the other gears
and increase the rate of wear.

Make sure the cover remains installed whenever
possible to keep the gears free of dust or debris
from the outside environment.

Lubricating
1.
DISCONNECT LATHE FROM POWER!
2.
Remove the headstock side cover and all the
end gears shown in Figure 121.
3.
Clean the end gears thoroughly with mineral
spirits to remove all the old grease. Use a
small brush if necessary to clean between
the teeth.

4.
Clean the shafts from which the end gears
were removed, and wipe up any old grease
splatters in the vicinity and on the inside of
the headstock cover.
splatters in the vicinity and on the inside of
the headstock cover.
5.
With clean hands, apply a thin layer of
grease on the gears. Make sure to get grease
between the gear teeth, but not so much that
it fills the voids between the teeth.
between the gear teeth, but not so much that
it fills the voids between the teeth.
6.
Install the end gears and mesh them
together with an approximate backlash of
0.005". Once the gears are meshed together,
apply a small dab of grease in the crux of
where the gears mesh together—this grease
will spread around when the gears start
moving and re-coat any areas scraped off
during installation.

Annual Maintenance
Once a year, remove all the end gears, clean
them thoroughly, and apply a new coating of
grease. Even if the headstock side cover has
been kept in place throughout the year, it is still
possible for dust from the V-belts to build-up
in the grease, and the grease may also start to
break down with extended or heavy use.
