The Royal Enfield Genuine Oil Pump Assembly with Pressure Relief Valve (Part No. 1570103/D) is a heart-line engine component designed for the advanced J-Series engine platform. This assembly is solely responsible for drawing engine oil from the sump and circulating it under precise pressure to critical overhead components, including the cylinder head, camshafts, and crankshaft bearings.
this updated assembly comes integrated with a factory-calibrated Pressure Relief Valve (PRV). The PRV plays a vital role in preventing oil seal blowouts by safely bypassing excess oil when internal pressures spike during cold starts or high-RPM riding. Utilizing the genuine 1570103/D oil pump ensures consistent lubrication film thickness, lower operating temperatures, and robust protection against premature engine wear.
