⚙️ Technical Insights
The Cummins 4891275 oil pump uses a gear-driven mechanism to deliver a steady oil flow, which is crucial for engine health. As the gears rotate, oil is drawn in and forced through passages that reach the crankshaft, bearings, pistons, and camshaft. Because this Cummins genuine part is built to exact tolerances, it prevents oil starvation and reduces the risk of metal-to-metal contact. Additionally, its precise pressure control supports efficient fuel burn and lower emissions, all while extending engine life.
