First up -- Logan 400 Lathe

After a general clean-up, the first task was to disassemble the head in order to replace the worn V-belt and to refurbish the bearings.

 The headstock bearings are 1) sealed and 2) one is a precision bearing only available through Logan. Don't be fooled into ordering the bearing from a bearing supply house; they stock the number, but not the "special" one.

Rather than buy a new bearing, I attempted (successfully) to re-grease the sealed bearings according to instructions for Scott Logan. First, I soaked the bearings in PineSol and then spun the inner race with an electric drill until no more debris was ejected. It took several attempts. Then, I wiped enough bearing grease on the outside of the bearings that approximated one-third to one-half of the inner volume of the bearings. (If they were made "full" they would run hot.) The bearings were then placed in a plastic bag from one of those vacuum-sealing devices my wife uses in the kitchen. Sucking the air out draws the grease inside the bearings. Job done!
