Bosch 0400864112 Fuel Injection Pump Assembly

The Bosch 0 400 864 112 is a mechanical in-line fuel injection pump designed for diesel engines manufactured by Deutz (KHD). It utilizes a plunger and barrel assembly for high-pressure fuel delivery to individual cylinders in firing order sequence. The pump housing integrates a mechanical governor for speed regulation and a feed pump for low-pressure fuel supply from the tank. This assembly serves as a direct OEM replacement for Deutz part numbers 0423 2525, 0423 2546, and KHD 04232525. It is constructed with high-precision hardened steel components to withstand the cyclic loading of heavy-duty industrial cycles. The pump calibration is set to Deutz engine specifications for injection timing, delivery volume, and smoke limit compliance. Cross-reference interchangeability includes Bosch service numbers F 002 A0Z 769 and 9 400 613 273.
