Fuel Injection Pump JDB435-2630 For 4276D Engine

Built as a dependable distributor‑type fuel injection unit, JDB435‑2630 is a purely mechanical pump engineered as an ideal replacement for 2630 tractor equipped with 4276D diesel engine. Free of electric‑driven control elements, it avoids breakdown risks triggered by harsh agricultural operating conditions including continuous vibration, field dust and elevated working temperatures. It can operate steadily with fuels carrying a certain amount of impurities, minimizing unexpected stops during busy farming seasons. Its plunger and delivery valve components are manufactured from high‑strength wear‑resistant alloy and precisely lapped, maintaining excellent high‑pressure sealing performance without internal leakage and prolonging the pump’s service life.
