Abstract:

A combination thrust-washer & pin configured unit that is inserted from the flywheel side of the joining crankshaft and flywheel. Bolted together with a step cut gland nut, the dowel pins are held at a right angle to the crankshaft torque direction thus eliminating deflection forces created by leaning pins. The dowels are held in proper right-angle shear configuration producing a strength gain over the standard dowels that are in the crankshaft only. Hole elongation of the crank is greatly reduced in hi-powered engine application that use dowel pin coupling. The thick thrust washer provides a press fit retainer for the pins and as a secondary benefit provides a superior clamping over the previous passive flatwasher methods where the pins are in the crank only.
