bEARING pAcKING INSTRUcTIONS
WARNING! Whenever a hub is disassembled (if a hub on a new unit requires assembly or a hub is
disassembled for maintenance), the following procedure MUST be obeyed.
Failure to read and obey all of the following instructions completely will void the warranty
and can result in damage to the Trailer, property damage, or serious injury.
a. Using a suitable solvent, thoroughly clean the
bearings and the rest of the parts in the Hub
assembly of all grease, dirt, metal shavings, or
any other foreign object. The parts must be
cleaned even if they are new or appear clean.
b. Allow all pieces to dry completely.
c. Make sure that your hands are thoroughly
clean and the bearing packer (not included)
is also thoroughly clean.
d. Place fresh, clean bearing grease in the packer.
e. With the grease-filled bearing packer in one hand
and the bearing in the other, press the bearing
into the grease, forcing the grease inside the slots
in the bearing. Continue doing this until every
slot in the bearing is completely full of grease.
f. Finish assembling the hub/wheel assembly,
being careful not to get any dirt or
debris on any part of the assembly.
20. Place the Outer Bearings (20) onto the
spindles of both ends of the Axle. Place a
3/4″ Flat Washer (N) onto each spindle of the Axle.
Then secure the Hub and Bearing assemblies,
using the Castle Nuts (K). (See Figure H.)

Cleaning (page 24). Make sure the Hub
rotates freely. If not, back off the Castle Nut
very slightly so that the Hub rotates freely.
22. Press a Dust Cap onto each Hub (18).
23. Place a Tire/Wheel Assembly (19) onto
