A2C80584700 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: A2C80584700. Application recorded for this part: Fits Nissan — Master 2.3 DC. 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. Symptoms associated with pump wear include hard starting when hot, loss of power, unstable idle, excess smoke, timing that will not hold, and in some cases diesel getting into the lubricating oil via a leaking drive shaft seal. Eliminate the cheap causes first: filter condition, lift pump output, suction-side air leaks, fuel quality. Only then have delivery quantity and timing tested before committing to a replacement unit. 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. 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.
