ROCKET PERFORMANCE GARAGE LLC 2022 FLTRX Road Glide Custom Harley Davidson OIL PUMP AND CAM PLATE `17-UP M8 TWIN COOLED. The Milwaukee 8 engine is now notorious for its oil sumping issues since its release in 217. �The Rocket Cams forged oil pump and camshaft support plate corrects the issues by separating the scavenge chamber for the crankcase and the cam chest with individual chambers and pump gears. �The oil cooled model has increased oil pressure and flow to get the oil through the passage ways of the heads quicker. �The forging process strengthens the aluminum by aligning the grain structure making it more durable than billet while making the components up to 25% stronger than the stock castings.. The vendor part number is 1900174.
