About this part
3417677 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 3417677, 3090942. Application recorded for this part: Fits Cummins — cummins QSNT M11.
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.
Set timing to the engine’s marks and never lever the pump into place — bar the engine over instead. Prime thoroughly, use a new mounting seal, verify lift pump supply pressure, and bleed before starting. A dry start is the fastest way to ruin a sound pump.
Rebuilt rather than refurbished: full teardown and measurement, worn components replaced instead of cleaned and reused, sealing surfaces restored to specification, then bench calibration and testing. The record is what separates this from a used part — we can provide the test sheet for your order. Covered by a 12-month warranty.
