Delphi has added six remanufactured diesel injectors and five diesel injection oil pumps to its diesel systems portfolio, covering almost 1.5 million light-duty Ford trucks (F-250 to F-550) on the road today.
During remanufacture, each injector is completely disassembled, cleaned and examined for wear and breakage. The nozzle, solenoid, screws, check balls, O-rings, armature screw, NOP spring, shim and stop are replaced with 100 percent new parts. After all critical components and worn-out or nonfunctioning parts are replaced with new parts, each injector is reassembled and tested to OE standards for compliance in fuel delivery, injection pressure and timing.
The five new diesel injection oil pumps, which are geared to support each of the remanufactured injectors, supply high-pressure oil to the intensifier side of the HEUI injector. Each is tested for proper pressure and operating parameters to help ensure the pressure meets OE specifications. The pumps are manufactured with new seals and O-rings, then tested and inspected to ensure quality and durability.
