FUEL INJECTION PUMP JDB435-3010 FOR 4276D ENGINE

The JDB435‑3010 is a heavy‑duty rotary‑distributor fuel injection pump adopting 100% mechanical governing system. Without any electronic control components, it avoids electronic failures caused by strong vibration, dust and high‑temperature exposure on farms and construction sites. Built for classic off‑road equipment, it operates reliably even with low‑grade diesel containing impurities and effectively cuts unexpected shutdown risks. Hardened wear‑resistant alloy is applied for plunger and delivery‑valve, which are finely ground to maintain steady high‑pressure sealing, eliminate internal fuel leakage and extend service life.

• Electronic‑free mechanical design, fewer failure‑prone points for harsh‑environment work
• Outstanding vibration resistance, stable fuel supply over rough farmland and worksite roads
• Reliable heat‑resistant performance for long‑time continuous heavy‑load operation
• Good adaptability to contaminated, low‑quality off‑road diesel fuel
• Hardened precision‑ground core assemblies, leak‑free high‑pressure sealing
• Precise fuel metering, smooth engine horsepower output and improved fuel‑burn efficiency
• Simple mechanical layout, convenient field inspection and low‑cost maintenance
• Fully bench‑calibrated and performance‑tested, direct‑fit aftermarket replacement
