I turns out that I wasn't too far off talking about a smear of JB Weld or Loctite. Loctite has a few products for "retaining and securing cylindrical assemblies". I'll list some below.
Loctite 660, a quick metal retaining compound, high strength (3335 psi) fills voids up to .02", temperature resistance 300 F, for repairing worn coaxial parts, tapers, bearing seats, key seats.
Loctite 609,general purpose retaining compound, medium strength (1870 psi), fills voids up to .005", temperature resistance 400 F, retention of bearings onto shafts and into housings.
Loctite 680, high strength (2800 psi), fills voids up to .015" temperature resistance 300 F, retaining compound slip fit, best resistanse to dynamic, axial and radial loads, for retaining shafts, gears, pulleys and similar cylindrical parts.
I measured the difference between my bearing and the shaft and I come up with .0007 or .0008. So what would be better fom my application. # 680 or # 609? Perhaps the 609 since it is medium strength and migh be easier to disassemble in the future? What temperature would the primary side crank bearing be exposed to? Peter
