2023 New Construction Oil pump with groove scavenger idler gear features a singular slot to the edge of the tooth to allow oil to eneter the chain oil cavity which is controlled by the chain oiler adjuster screw.Replace your vintage Harley Davidson FL oil pump scavenger drive gear with the reliable Motorshop part designed specifically for models from 1936 through 1945. This gear features a groove milled into the side to engage the rotor when installed on 1941-1949 oil pumps, ensuring smooth and efficient operation. The drive grooves are strategically placed and do not extend entirely across the tooth profile, precisely driving the centrifugal rotator vane. For 1936-1940 models, the oil pump scavenger idler gear is not a keyed component; instead, it has a single slot to facilitate oil flow through the hole to the primary chain for lubrication. This slot can be adjusted using screws with shims to optimize oil delivery. In 1941 models, the design shifts to a rotor and feed located on the back side, with the adjuster screws going straight in for easier maintenance. Models from 1942-1949 feature a rotor with a face that includes two slots for engaging the drive rotator and one slot on the rear side for chain oiler feed. The gear itself incorporates relief shots to support chain oiler feed, contributing to effective lubrication and prolonged engine life. The adjuster screw, controlled by a screw, shim washer, and nut, allows for precise tension adjustment, ensuring optimal gear engagement and durability. Crafted in Taiwan, this OEM cross-referenced part offers dependable performance and compatibility with your classic Harley Davidson FL motorcycle. Proper installation and maintenance of this gear are essential for maintaining oil flow and engine longevity. Along with the gear, consider accessory items such as the oil pump snap ring installer, factory-style drill jig tool, and additional idler gears to facilitate installation and service. Invest in this high-quality scavenger oil pump drive gear to keep your vintage Harley running smoothly and reliably.
