Change Gears
Grease Type ............................................... NLGI#2
Frequency ................ Annually or When Swapping
The change gears, shown in
Figure 130
, 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 will be flung onto the V-belts, which
will cause the belts to slip and the lathe to lose
power.

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 end gear cover.
3.
Clean the change 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.
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.
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 change gears, clean
them thoroughly, and apply a new coating of
grease. Even if the end gear 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.
