0440011002 is supplied as a remanufactured replacement priming pump. Cross-reference numbers: 0440011002. Application recorded for this part: 044. 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. The pattern is normally cumulative: slightly harder starting, then noticeable power loss, then smoke and unstable idle. Where the drive seal has failed, diesel in the lubricating oil is the warning that should stop you running the engine. 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. 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.
