This 5/16" brass pin punch allows you to remove 8mm, R6 or 3/8" and R8 or 1/2" bearings found in your wheelchair's rear wheel hub, front fork, and front casters.
If you want your wheelchair to move faster, go farther and smoother, then you have to maintain your wheelchair’s bearings. Your wheelchair has bearings in three places: front caster, front fork, and rear wheels. Most wheelchair manufacturers say you need to re-grease or change your front caster bearings yearly, and the forks and rear bearings as needed. With the right tools, this is easy to do. This 5/16" brass pin punch allows you to remove 8mm, R6 or 3/8" and R8 or 1/2" bearings found in your wheelchair's rear wheel hub, front fork, and front casters.
Problem 1: Flathead screwdrivers unevenly remove a bearing causing damage to the caster, front fork stem or rear wheel camber tube.
Problem 2: Most punches do not have long enough necks to reach through a rear wheel wheelchair hub to knock out the bearing
Problem 3: Most pin punches are made of hardened steel. This can damage the bearing if you want to re-grease and reuse it.
