Contrary to the OEMcrankshaft in 1990-1999 models these crankshafts feature a separate sprocket shaft and pinion shaft, which makes a rebuild possible. Another great advantage is that the 1984-1989 style pinion shafts have proven to be much stronger as the OEMdesign used in 1990-1999 models. Crankshafts are ready to install and balanced by S&S for use with stock pistons. Great for engine new builds and rebuilds. 1935 S&S CRANKSHAFT ASSEMBLY FOR EVOLUTION BIG TWIN 782608 S&S 1991 thru 2003 Sportster crankshaft assembly (OEM 23905-00, S&S 320-0053) S&S pinion gears for S&S flywheels in all 1986-2003 Sportster 750076 Red, OEM 24057-86 750077 White, OEM 24058-86 Optional parts required for installation in 1988 thru 2003 models 231835 Pinion gear nut, dealer 5-pack (OEM7913) CNC machined from heat-treated, closed die, steel forgings, and stronger than cast iron or late stock style steel flywheels.

These have proven to be much stronger as the OEMdesign used since 1988. Crankshafts are ready to install and balanced by S&S for use with stock 1200 cc pistons.

Stronger, more durable, and trued to a spec others can only dream of, these crankshaft assemblies for the Milwaukee Eight are the best of the best to build your high performance engine around. Made out of heat treaded 4140 material, harder and more than twice as strong as stock. The stronger assembly eliminates the need to weld the crankpin. The High Strength connecting rods are designed with Finite Element Analysis to eliminate weak spots and handle more power. Consistent balance and precision machining makes them capable of higher RPM and perfect for gear drive cams. Crankshafts that have connecting rods with tapered piston wrist pin ends can be used with stock or S&S pistons. The full-width version can only be used with S&S pistons and S&S Big Bore cylinder kits. Crankshafts with 4 5/8" stroke can only be used with pistons that are designed for this stroke. 4 5/8" stroke gives: - 113CI from a 107CI engine with stock 3 15/16" bore - 117CI from a 114CI engine with stock 4 1/64" bore - 121CI from a 117CI engine with stock 4 5/64" bore - 131CI with an S&S 4 1/4" Big Bore kit 1931 S&S HIGHPERFORMANCE MILWAUKEE EIGHT 3PIECE FLYWHEEL ASSEMBLIES CRANKSHAFT PARTS (Ȧ*ȡ1ȝ (Site 433)
