Using a wheel dolly place wheel on spindle; care must
be taken not to damage the seal, especially on the
leading edge of the spindle or axle (Fig. 11).
INITIAL LUBRICATION OF WHEEL BEARINGS
Transparent Hub Cap (Front Axle)
Add oil through filler plug hole in hub cap allowing time
for oil to seep through the bearings and seek a level on initial
fill. When properly filled oil should be on or 9.5 mm (3/8")
above the oil level mark on the hub cap window. Use engine
oil or gear oil for front wheels (see LUBRICATION, Section
CTS2412).
Hub Cap Without Window (Front Axle)
Add .71 liter (1-1/2 pints) of matching differential
lubricant or enough lubricant to touch the bottom surface of
the wheel spindle outside diameter of each front wheel. For
initial fill, pipe tap hole should be at.12 o'clock position.
Add oil through pipe tap hole in axle shafts. Fill until oil runs
out of filler hole when positioned at 4 to 5 or 7 to 8 o'clock
positions [approximately .71 liter (1-1/2 pints)].
TRACTOR DRIVE WHEELS (Rear Axle)
Dip bearing cones in lubricant.
Before installing outer cone fill the wheel cavity
between bearings with the same oil to be used in differential.
This will assure bearing and spindle lubrication until
lubrication creeps through the outer bearing.
NOTE: The differential must not be over-
filled. A periodic check is to be made for
proper lubricant level.
On tractor drive wheels, apply Loctite gasket eliminator
(sealant) material No. 504 to back of axle flange and install
axle (Fig. 12).
