0414401102 is supplied as a remanufactured replacement unit pump. Cross-reference numbers: 0414401102. The injection pump is what generates injection pressure and meters fuel to each cylinder in firing order. Because it also provides the timing reference, its condition affects starting, smoke, power and fuel consumption together — a pump that is worn rarely produces a single isolated symptom. Expect extended cranking especially when hot, hesitant throttle response, smoke that persists rather than clears, timing that drifts or will not hold, and in some cases fuel in the sump or a pump body running unusually hot. 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. Key points: align to the timing marks rather than forcing the drive, prime before cranking, renew seals, confirm adequate supply pressure from the lift pump, and bleed the system fully. Skipping any of these is where most comebacks originate. Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
