These instructions have always cornfused me. If the bearing is pressed against
the "... abutment shoulder in the hub
..." there won't be much adjustment possible (unless you have a press strong
enough to compress the hardened steel
bearing race, and distort it). The only way to adjust the 'protrusion' would
be to use differing width spacers. I've
always interpreted this as 'make sure the spacer is at least a slight bit above
the face of the hub.' If it isn't, you
probably have an ill-fitting bearing.
Or am I missing something?
