Bosch original Diesel Fuel Injection Unit Pump 0414755118, for heavy duty diesel engine application, 04262056, 10116257 - OEM Replacement for Trucks, Crawler Excavators original new injector

Engineered for Liebherr heavy-duty diesel platforms, the BOSCH 0414755118 unit pump injector belongs to the Bosch 755 Series and operates within the proven Unit Pump System (UPS) architecture. Supplied to OEM standard, it directly cross-references Bosch 0 414 755 118, previous number 0414755018, Liebherr 10116257, and type number PLD1B100/520/24S180, giving distributors and fleet operators a fully interchangeable replacement solution.

Within the UPS layout, each cylinder carries an independent high-pressure fuel generation and injection unit. The engine control unit precisely governs injection timing and quantity; the needle valve opens under controlled pressure, and diesel is atomized into microscopic droplets through precision-engineered nozzle holes. This delivers optimized combustion with clear advantages: precise fuel metering, reduced fuel consumption, lower exhaust emissions, improved power output, better cold-start performance, and extended engine service life in continuous heavy-duty operation.

Verified engine fitment covers the Liebherr D934, D934SAG, D934T, D936, D936L, D936LA, D936TI, and D936 Industrial Series, powering equipment such as the L538, L566, and L580 wheel loaders and R944 and R954 excavators, as well as mining, quarry, and industrial power equipment. Bosch engineering delivers high-pressure injection capability, corrosion protection, and superior durability for long service life and reduced operating costs. For reliable performance, install with new sealing components, tighten to OEM torque specifications, bleed the fuel system, and maintain with ultra-clean diesel and scheduled filter replacement.
