End Gears
Lube Type . . Model T23964 or NLGI#2 Equivalent
Frequency ............... Annually or When Changing
The end gears, shown in Figure 131, 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 cover remains installed when-
ever 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
shown in Figure 131.
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
cover.
5. Using a clean brush, apply a thin layer of
white lithium grease on the gears. Make sure
to get grease between gear teeth, but do not
fill teeth valleys.
6. Apply a small dab of grease to each gear
shaft.
7. Install end gears and mesh them together
with an approximate 0.002"–0.004" backlash.
Once gears are meshed together, apply a
small dab of grease between them where
they mesh together—this grease will be dis-
tributed when gears rotate and re-coat any
areas scraped off during installation.
8. Re-install end cover before re-connecting
machine to power.
