Lubricating
Proper lubrication of ball oilers is done with a
pump-type oil can that has a plastic or rubberized
cone tip (see Accessories section, beginning on
Page 55). Do not use the metal-tipped oil bottle
included with the G0750GV tools, as it can push
the ball too far into the oiler, break the spring seat,
and lodge the ball in the oil galley.
Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside sur-
face to remove any dust or grime. Push the rub-
ber or plastic tip of the oil can nozzle against the
ball oiler to create a hydraulic seal, then pump the
oil can once or twice. If you see sludge and con-
taminants coming out of the lubrication area, keep
pumping the oil can until the oil runs clear. When
finished, wipe away any excess oil.

Removal & Replacement
To remove a damaged ball oiler, thread a coarse
wood screw and flat washer partially into the ball
oiler. Place an open-end wrench under the wash-
er, then carefully pry out the ball oiler.
Clean out the ball oiler opening. Verify no broken
ball oiler parts remain in component oil galleys.
Note: You may need to disassemble a compo-
nent to remove broken ball oiler parts.
To install the new ball oiler, freeze it for an hour
or two, then press or tap it into the bore until flush
using a piece of wood.
End Gears
Grease Type ...... T26419 (or NLGI#2 Equivalent)
Frequency ............... Annually or When Changing
The end gears, shown in Figure 114, 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.
