If you're overhauling an older motorcycle engine or building a lubrication system from scratch, consider the turnkey ease of S&S Cycle oil pump kits. They offer the same width oil supply and return gears as a stock Harley-Davidson® aluminum pump, but these driveshaft gears increase potential oil volume delivery by 25 percent over stock on some engines. S&S pumps are machined with an oil pressure bleed-off passage, relieving pressure build-up on top of the valve to maintain consistent oil pressure. Excess oil is also routed directly to the supply side of the pump to reduce the amount returned to the tank—which means less foaming and cavitation. The kits are available for a variety of bikes, including Big Twin models. S&S Cycle oil pump kits include: * Complete oil pump assembly * Pinion shaft pump drive gear * Oil pump driveshaft gear * Breather gear * Mounting hardware * Fittings and gaskets * Instructions
