Great video! I have the other “more expensive” bearing. Is there a trick or
special order to install it?
Even better, put the bearing in your freezer overnight and heat the pulley
in an oven, pull out and quickly insert bearing with minimal pressure.
Good video. However, by pressing on the pulley last, you are placing all
the force on that outside race of the bearing. Potentially greatly
shortening its life. I would suggest pressing the bearing into the pulley
first using a spacer on the outer race. Then press the bearing/pulley
assembly onto the shaft using a spacer on the inner race.
