S&S CYCLE Oil Pump with Cam Plate 3100731

Precision CNC machined forged aluminum. Increased structural strength. Dimensional stability. Freedom for internal porosity. Separate scavenge sections for flywheel cavity and cam chest scavenge each area more efficiently with no interference. Gerotors are designed to tolerate more pinion shaft runout without damage. Cam chest pic up features a magnetic trap to protect scavenge rotors from metal debris. Both scavenge rotors are protected from debris, the most common cause of stock oil pump failure. Passage plugs are removable for service. Bronze pinion shaft bushing in all models and bronze cam bushings in 07-15 style can be replaced. Adjustable oil pressure regulator - adjust without removing plate from engine. 99-06 cam support plate is designed to use late style hydraulic cam chain tensioners because stock spring-loaded tensioners used in 99-06 models don't adequately control the valve train at high rpm, especially with higher lift cams or performance valve springs. Made in the U.S.A.
