Changing Wheelchair Caster Wheel Treads and Bearings
[ Tuesday May 31st 2016 at 9:20 am ]
This video contains the series of steps each with an accompanying photograph to show how to change a wheelchair caster wheel tread and its bearings. I've made this video to be the same idea as a service manual or "Power Point" presentation so the video may be paused as the work as performed. A replacement tread and bearings are necessary to complete the work. The tools used were a #3 Philips screw driver to remove the hub cap bolts, a #3 flat-head screw driver to remove the worn bearing, a rubber mallet to seat the new bearing and either a hydraulic press or wood and 2 clamps to seat the hub cap into the caster wheel tread. Additionally a heat gun and refrigerator or freezer may be necessary for thermal expansion and shrinking if the replacement bearing is a tight fit.
