About this part
28672159 is supplied as a remanufactured replacement fuel injection pump. Cross-reference numbers: 28672159, 1111100-011, S01000-1111100. Application recorded for this part: Fits Yuchai — (S01000-1111100-011).
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.
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.
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.
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.
