End Gears
Grease ..... Grizzly T23964 or NLGI#2 Equivalent
Frequency ............... Annually or When Changing
The end gears, shown in Figure 139, 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.

Handling & Care
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 end gear cover remains installed
whenever possible to keep the gears free of dust
or debris from the outside environment.
Lubricating
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove end gear cover and all end gears
(see Figure 139).
3.
Clean end gears thoroughly with mineral spir-
its to remove old grease. Use a small brush if
necessary to clean between teeth.
4.
Clean shafts and wipe away any grease
splatters in vicinity and on inside of end gear
cover.

Lubrication
Port
5.
Using a clean brush, apply a thin layer of
grease on gears. Make sure to get grease
between gear teeth, but do not fill teeth
valleys.
6.
Install end gears and mesh them together
with an approximate 0.002"–0.004" backlash.
Once gears are meshed together, apply
small dab of grease between them where
they mesh together—this grease will be dis-
tributed when gears rotate and recoat any
areas scraped off during installation.
7.
Re-install end gear cover before reconnect-
ing lathe to power.
Mill Leadscrew
Lube Type ..Model T23964 or NLGI#2 Equivalent
Lube Amount ........................................Thin Coat
Lubrication Frequency ....................... As Needed
Before lubricating the mill leadscrew (see Figure
140), clean it first with mineral spirits. A stiff brush
works well to help clean out the threads. Make
sure to move the headstock of the way, so you
can clean the entire length of the leadscrew.
When dry, apply NLGI#2 grease to exposed
leadscrew threads. Move headstock through its
full range of motion several times to disperse
grease along full length of leadscrew.
