Sealed
Wheel Bearing and Shielded Wheel Bearing
numbers are imprinted on both side covers of the bearing.
Bearing Installation: A bearing
press or similar pressing tool should be used to exert the force
needed to press the bearing into the wheels hub. A Homemade
Wheel Bearing Press for installing sealed bearings into aluminum electric
scooter and electric bike wheels can be made from the following materials which
are available at all hardware stores and home improvement centers:
1- 8" long
x 3/8" diameter bolt 4-
3/8" fender washers (must be larger than the bearing being pressed)
1- 3/8" nut
To use
this tool place two fender washers onto the end of the bolt
and insert the bolt between the two bearings and the hub. Then place two fender washers
and the nut on the end of the bolt and tighten the
nut and bolt together to carefully press the bearings into
place.
Care needs to be taken so that the bearings are
started out perfectly straight and not at an angle to the hub. Tighten the
bearing press until the fender washers are pressed flush against the ends of the
wheel hub to properly seat the bearings.
