Doosan is a major South Korean manufacturer of construction equipment and industrial engines, with their D1146 and P086 series inline-6 diesel engines widely deployed in excavators, wheel loaders, and power generation equipment across global markets. These are high-displacement, high-output engines requiring a robust fuel injection pump to deliver precise fuel metering across all six cylinders. When the injection pump fails, you'll experience hard starts, rough running, power loss, excessive black smoke, or a complete no-start condition — causing costly downtime on job sites or in power generation applications. This brand-new aftermarket fuel injection pump is a direct replacement covering eight cross-reference formats (A/B/C suffix variants) of Doosan OEM part number 65.11101-8009.
