Bosch original Fuel Injection Pump 10116257 Replacement for Unit Pump Fit for Liebherr D934 D936LA6 D934SAG Heavy Equipment Engine Parts, for heavy duty diesel engine application original new injector

Engineered for high-pressure, heavy-duty diesel power, the BOSCH 755 Series Fuel Injector Unit Pump (OE 10116257) is a precision-built injection component manufactured to Bosch OEM industrial quality standards. It is fully interchangeable with Bosch alternates 0414755118 and 0414755018 (0 414 755 118 / 0 414 755 018) under internal code PLD1B100/520/24S180, and mounts on the engine head / fuel rail within Bosch common rail and unit pump (UPS) systems.

Advanced Bosch fuel metering technology, hardened alloy steel internals, and high-grade seals enable the unit pump to meter, time, and atomize diesel with exceptional accuracy. Its precision-machined nozzle produces a uniform spray pattern at high injection pressure, while advanced flow calibration and tight manufacturing tolerances keep output consistent. For operators, this delivers efficient combustion, reduced emissions, lower fuel consumption, stable engine performance under load, and longer service life, supported by corrosion-resistant materials and industrial-grade testing.

Compatibility covers Liebherr D934, D934S, D936, D936LA, and D936A7 engines, with applications spanning construction machinery such as excavators and loaders, mining power units, heavy trucks, industrial diesel generators, agricultural machinery, marine auxiliary power units, and material handling equipment. Every unit ships in industrial protective packaging with seller warranty coverage. To protect injection performance, the fuel system should be cleaned before installation, seating surfaces inspected, washers and O-rings replaced, OEM torque specifications followed, and ECU coding plus leak testing completed where required.
