Bearing Packing Instructions
Important
Read and adhere to the following instructions; 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 PERSONAL INJURY.
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 followed.
1. 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.
2. Allow all pieces to dry completely.
3. Make sure that your hands are thoroughly clean and the bearing packer (not included) is also
thoroughly clean.
4. Place fresh, clean bearing grease in the packer.
5. With the grease-filled bearing packer in one hand and the bearing in the other, press the bear-
ing 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.
6. Finish assembling the hub/wheel assembly as explained in this manual, being careful not to
get any dirt or debris on any part of the assembly.
