2.
Install bearings and place hub on spindle in
reverse order as listed in the Section F6-A - "Re-
moval of Hub". Rotate the hub while applying
approximately 50 ft-lbs. of torque to the spindle
nut. This translates into a full hand pressure load
with a 12" long wrench. This "seats" the bear-
ings.
3. Loosen the spindle nut to remove the torque ap-
plied. DO NOT ROTATE THE HUB.
4. Tighten the spindle nut until snug, backing off
only enough to line up the cotter pin with the hole
in the spindle.
5. Bend the cotter pin into place.
6. Load hub with "Lucas Oil Marine" grease using
the instructions for adding or changing grease
Section F5-J - "Bearings" and/or manufac-
turer's Literature.
7. Replace the Vortex grease cap. Turn in a clock-
wise rotation until the o-ring on the cap comes in
contact with the hub surface. Turn an additional
1/4 turn to seal the Vortex cap to the hub. (This
is similar to installing an oil filter in an automo-
bile).
8. Replace tire/wheel, torque lug nuts according to
wheel manufacturer's instructions.
9. Test hub for proper end play by grabbing the tire
and pulling the tire from side to side. Readjust if
necessary.
NOTICE:
IMPORTANT
Re-check lug nuts after 25 miles of use.
Refer to Sections F-2F and the F-7 for additional
informa tion.

SUPPLEMENTAL TRAILER INFORMATION
A. Information Contained on Sidewall of the Tire
Both U.S. and Canada Federal regulations require
tire manufacturers to place standardized information
on the sidewall of all tires. This information identi-
fies and describes the characteristics of the tire. See
Figure F21.
Trailer Information - Section F
Figure F21: Axle Components
Maximum Permissible Inflation Pressure: Indicates
the tire manufacturer's maximum permissible pres-
sure and/or the pressure at which the maximum load
can be carried by the tire. Refer to the Certification
Label on the port forward half of the trailer for the
correct tire pressure for your trailer.
U.S. DOT Tire Identification Number (TIN): This
begins with the letters 'DOT' and indicates the tire
meets all federal standards. The next two numbers
or letters are the plant code designating where it was
manufactured, the next two are the tire size code,
and the last four numbers represent the week and
year the tire was built. For example, the numbers
5110 mean the tire was built the 51st week of 2010.
The numbers are identification codes used for trace-
ability. This information is used to contact customers
if a tire defect requires a recall.
ST: Indicates the tire is a special tire for trailers in
highway service.
215: Indicates the nominal width of the tire in millime-
ters from sidewall edge to sidewall edge. In general,
the larger the number, the wider the tire will be.
65: Indicates the aspect ratio which gives the tire's
ratio of height to width.
R: Indicates a "radial" type tire.
15: Indicates the wheel or rim diameter in inches.
Tire Ply Composition and Materials Used: Indicates
the number of plies or the number of rubber-coated
fabric in the tire tread and sidewall. Tire manufactur-
ers also must indicate the ply materials in the tire and
the sidewall, which include steel nylon, polyester,
and others.
