Will the spacer ring come out after the hub is heated or is it a non removable item?
Just out of curiosity it seems like it would make sense on the installation process to remove the spacer ring (part G in diagram) and press the outer bearing in 1st. After this I would drop the cylinder in, followed by the inner bearing and press it in with something until it sits flush with the cylinder.
Does it help to freeze the bearings for installation and if I do freeze them will I need to heat the hub again?
I’m aware that extremely hot things that are cooled down too quickly can sometimes crack (glass for example). Is this true of bearing material or no?
Might be a simple thing for others, but as this is my first time doing it I want to be aware of what can be damaged so I can avoid having to spend money unnecessarily.
