518093 Crankpin 29-73 Flathead

For those working on the legendary 45-cubic inch (750cc) Flathead, this crankpin is a necessary component for a proper bottom-end rebuild. It fits all 45-inch Flathead models produced between 1929 and 1973, including the long-running Servi-Car. This part is a direct replacement for the original equipment part number 23960-29. As the central pivot for the connecting rods, the crankpin must be perfectly round and durable to withstand the stresses of the internal combustion cycle. This MCS replacement ensures that your vintage V-twin remains on the road with the same mechanical reliability it had when it left the factory.
