RE: Exceed Monster Power 160
OH, Yes. Both of mine have been completely rebuilt. Re-soldered 12AWG wires, Re-glued magnets, new bearings and shaft. On one the stater came loose and had to be glued back on. As long as the case doesn't get bent or the coils damaged, it's easy to rebuild. McMaster-Carr has class 5 bearings and metric hardened drill blanks. Always buy 2 or 3 shafts, because technically they are the same size as the bearings and sometimes don't slide through. Bearings have a tolerance of -0.000 +0.005mm and the drill blanks tolerance is -0.005 +0.000mm. So there could be 0.01mm difference which slides in easy or 0 difference which would need to be pressed (don't), but mostly they slide with a little push.
