The sleeve, which fits over the crankshaft, fastens both inner races of both bearings mechanically to the crankshaft. The front end seal is machined onto that same sleeve. Crankshaft endplay is set at .003 to .004 with machined spring steel shim washers to be shown. Even at elevated running temperatures, the end play remains the same, because all parts; the crankshaft; the sleeve; the shims; the front end; & the bearing races; ARE ALL MADE OF STEEL! This system also works with all metal bearings, but CERAMICS WILL RUN FASTER, LONGER!
