Sealed Wheel Bearing Removal
A hammer and punch or a shop press and punch are commonly used to remove sealed wheel bearings from wheel hubs. Tap or press the wheel bearings out gently and evenly to avoid damaging the wheel hub.
Sealed Wheel Bearing Installation
A homemade wheel bearing press or a shop press and punch are commonly used to exert the force needed to press the bearings into the wheels hub.
Homemade Wheel Bearing Press
A homemade wheel bearing press for installing sealed bearings into aluminum electric scooter and bike wheels can be made from the following materials which are available at all hardware and home improvement stores:
1- 8" long x 3/8" diameter fully threaded machine bolt
4- 3/8" fender washers (must be larger than the bearing being pressed)
1- 3/8" nut
Place two fender washers onto the end of the bolt and insert the bolt between the two bearings and the wheel hub.
Place two fender washers and the nut on the end of the bolt and tighten together with wrenches to press the bearings into place.
Make sure the bearings start out perfectly straight and that they are not at an angle or misalignment 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.
