About This Product
When you are rebuilding the bottom end of a classic 45" Flathead, precision is everything. This steel flywheel thrust washer set is designed for use with steel retainers, fitting perfectly between the connecting rods and the flywheels to maintain proper lateral clearance. These washers are 0.065 inches thick and serve as a reliable replacement for OEM 23972-21B. They are sold as a pair and are suitable for all 45 cubic inch Flathead models produced between 1929 and 1973. Using high-quality steel components in the crankcase ensures your vintage V-twin stays within factory tolerances for smoother operation and longevity.
Manufacturer part number: 517982.
