Adding Pull Knob To Wheelchair Stem Bearing Dust Cover
[ Monday May 1st 2017 at 12:51 pm ]
In this video I show how I've added a kitchen pot lid knob to my wheelchair stem bearing dust caps. Without this the stem bearing dust cap plastic becomes carved as it is repeatedly removed for replacing bearings. This forms a channel for water, salt, sand and grit to get into the bearing and cause the bearing to prematurely fail. In extreme cases this will cause the bearing to seize in place.
