About This Product
Samwel oil pump drive gear for 1937 to 1973 45" Sidevalves and 1954 to 1977 K, KH, and XL Sportster models. This gear drives the oil pump from the pinion shaft. Worn teeth or a loose bore cause erratic oil pressure. Inspect the bore and keyway before fitting. A sloppy gear will wreck the pump drive. Replaces OEM 26318-37.
Manufacturer part number: 12-0421.
