About this part
5801439062 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 5801439062, 0445010320, 0445010319. Application recorded for this part: Fits IVECO — 2.3.
This unit sets both quantity and timing for every cylinder. Modern engines depend on that timing being accurate to well under a degree, so internal wear that would once have been tolerated now shows up as smoke, noise and failed emissions checks.
Typical indicators are progressively harder starting, particularly when hot, reduced power, smoke under load, erratic idle, and fuel dilution in the sump — the last one should always be investigated immediately.
Check supply pressure at the pump inlet and look for air in the clear line before assuming internal wear. Plenty of pumps get replaced for a blocked filter or a suction leak that costs a fraction to put right.
Fitment notes: this unit must be timed to the engine, not simply bolted on. Never force the shaft to align — turn the engine over to meet it. Prime the system before cranking, fit a new drive seal where specified, and verify supply pressure from the lift pump before start-up. Running a dry pump, even briefly, causes damage that no warranty will cover.
How we build it: the unit is fully disassembled, cleaned and measured, not simply resealed. Wear items — seals, springs, and where clearance is out of specification the plunger and barrel or nozzle assemblies — are replaced rather than reused. Sealing faces and bores are re-machined back to original clearances, then the unit is calibrated and run on a bench with delivery, return flow, opening pressure and leakage recorded. Anything outside specification does not ship. Test sheets for your specific units are available on request. Covered by a 12-month warranty.
