Lang Tools Crankshaft Bearing End Play Setup Tool For Harley 1936-1999 Features This tool is used to set up crankshaft bearing end play Consists of a large precision machined bolt and nut Outer bearing races are pressed into the crankcase and the inner races along with the shims are assembled in the crankcase Using a dial indicator, end play is then measured Disassemble and change shims until desired end play is reached The diameter of the bolt is turned slightly smaller than the actual crankshaft diameter allowing the inner bearing races to be installed and removed without pressing them on or off Allows for much faster changing of shims, and therefore faster setup time
