GENUINE SDF 4-Hole Mechanical Diaphragm Fuel Lift Pump for Same, Lamborghini & Hürlimann Tractors - Part Number: 2.4519.230.0/10
The GENUINE SDF (Same Deutz-Fahr Original Parts) mechanical diaphragm diesel fuel feed pump (part number 2.4519.230.0/10, related cross-references 2.4519.290.0, 2.4519.220.0, 2.4519.230.0) is a camshaft-driven primary fuel supply unit engineered to deliver steady low-pressure diesel flow from the tank to the main fuel injection pump. Built with an original equipment 4-hole mounting flange (vertical hole spacing = 25 mm, horizontal hole spacing = 45 mm), it is actuated by the engine camshaft eccentric lobe and features an integrated manual priming hand lever to facilitate system bleeding during routine maintenance. Manufactured to exact SDF factory specifications, it guarantees positive sealing and direct fitment across wheeled and crawler tractors from Same (Laser, Centauro, Corsaro, Buffalo, Drago, Saturno, Taurus, Minitaurus, Vigneron), Lamborghini (Series 1000, C-Series crawlers, R-Series 600–1000), and Hürlimann (H-Series 351–H 6170).
Key Features & Engineering Advantages
- 100% Genuine SDF Factory Part: Manufactured to strict Same Deutz-Fahr OEM metallurgical and machining standards, ensuring exact rocker arm geometry and zero oil leaks at the engine mounting interface.
- Precision 4-Hole Mounting Pattern (25 x 45 mm): Ensures an accurate and rigid bolt-on fit against the engine block, maintaining correct alignment between the rocker arm and the camshaft lobe.
- OEM-Grade Multi-Layer Diaphragm: High-resilience synthetic elastomer membrane resists degradation from standard diesel, sulfur variants, and modern biodiesel (EN 590 / FAME), preventing fuel dilution into the crankcase oil.
- Integrated Hand Priming Lever: Enables rapid manual bleeding of air bubbles from the fuel circuit and quick filter refilling after field servicing without unnecessary starter motor strain.
- Factory-Calibrated Internal Check Valves: Precision spring-loaded check valves prevent fuel drain-back to the tank when the tractor is stopped, guaranteeing fast engine cranking and smooth cold starts.
- Comprehensive SDF Group Compatibility: Direct-fit replacement for 3, 4, 5, and 6-cylinder diesel engines across Same (916.3, 916.4, 1000.6, 1054, 105.4, 105.5), Lamborghini (984, 986), and related Deutz applications.

Installation Advice & Workshop Notes: Thoroughly clean and degrease the engine block mounting surface, making sure all residue from the old gasket is removed. Turn the engine crankshaft so the camshaft driving lobe is positioned at its lowest lift profile to avoid preloading the rocker arm while threading the mounting nuts. Always install a new genuine SDF gasket of the recommended thickness to preserve factory rocker travel and output pressure; torque the four mounting nuts (25 x 45 mm spacing) in a crisscross sequence. Reconnect the fuel lines, then operate the manual priming lever until bubble-free diesel fuel flows from the fuel filter bleed points.
