About this part
0460424260 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 0460424260, 3991098, 12F1250R840-8. Application recorded for this part: VE VE4/12F1250R840-8.
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.
Diagnose the supply side before blaming the pump. Restricted filters, a tired lift pump or air being drawn into the suction line will produce symptoms almost identical to internal pump wear, and are far cheaper to resolve.
Installation notes: never rotate the pump by force to align it — bar the engine over instead. Prime before cranking, renew the drive seal, confirm supply pressure, and bleed the system properly. Dry running for even a few seconds is the most common cause of premature failure on an otherwise sound pump.
Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
