Change Gears
Grease Type ............................................NLGI#2
Oil Amount ............................................Thin Coat
Frequency ............... Annually or When Changing
The change gears, shown in Figure 86, should
always have a thin coat of heavy grease to
minimize corrosion, noise, and wear. Wipe away
excess grease that could be thrown onto the
V-belts and reduce optimal power transmission
from the motor.
Figure 86. Change gears.
To handle and care for the change gears:
Make sure to clean and lubricate any gears you
install or change. Be very careful during handling
and storage—the grease coating 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 change gear cover remains installed
whenever possible to keep the gears free of dust
or debris from the outside environment.
To lubricate the change gears:
1. DISCONNECT LATHE FROM POWER!
2. Open the change gear cover and remove all
the change gears shown in Figure 86.
3. Clean the change gears thoroughly with min-
eral spirits to remove the old grease. Use a
small brush if necessary to clean between the
teeth.
4. Clean the shafts, and wipe away any grease
splatters in the vicinity and on the inside of
the change gear cover.
5. Using a clean brush, apply a thin layer of
grease on the gears. Make sure to get grease
between the gear teeth, but do not fill the
teeth valleys.
6. Install the change gears and mesh them
together with 0.003"–0.008" backlash. Once
the gears are meshed together, apply a small
dab of grease between them where they
mesh together—this grease will be distrib-
uted when the gears rotate and re-coat any
areas scraped off during installation.
7. Close the change gear cover before re-con-
necting the lathe to power.
