Finally getting around to installing some new headstock spindle bearings in my trusty EXL 56B. Original factory bearings being replaced with Timken class 3 brgs and cups. The question I have is, what would be a suitable break in time and speed for the new bearings/cups. Given the price and availability of these parts I only want to do this once.
