Hello all, I'm in the process of restoring my Thorens TD 124 Mk I and have been reading up on a lot of expert advice and opinions on the process. I'm at a point where I need to clean the sintered bronze bearings for the platter. I've heard you need to heat up the bearings in the oven, is that correct? If so, what is the step by set process. do I need to pull the bearing out of the well? Any help would greatly be appreciated. Thanks.
