S410195117008 Flat O-ring, kickstart shaft

When you are working on a kickstart assembly, the shaft seal is often the culprit behind annoying primary leaks. This Athena flat O-ring is designed to sit perfectly between the bushings of the kickstart shaft to provide a tight seal. It fits a wide range of models, including 1952 to 1979 K models and XL Sportsters, late 1937 to 1969 FL models, and 1971 to 1986 4-speed FX models. This O-ring is a direct replacement for OEM 33076-37 and 2078-37. Using a fresh seal during your transmission or primary service is the best way to ensure your kicker shaft stays dry. Athena's precision manufacturing ensures this O-ring maintains its shape and sealing properties even after countless kicks, making it a staple for any vintage workshop.
