400912-00062 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 400912-00062, 400912-00052. Supply pressure, timing and delivery quantity are all set here. Failures tend to progress gradually — a little more smoke, slightly harder starting when hot, slowly rising consumption — which is why they are often attributed to the injectors before the pump is checked. 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. 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.
