291-5911 is supplied as a remanufactured replacement injector. Cross-reference numbers: 291-5911, 2915911, 10R7230, 10R-7230. Application recorded for this part: C18. The injector sits at the end of the rail and does the final metering work: it receives fuel already at high pressure and decides both how much enters the cylinder and how well atomised it is. That combination governs power, smoke and fuel consumption more directly than almost any other part on the engine. Common indicators are rough or unstable idle, smoke that was not there before, higher fuel consumption on the same duty cycle, diesel knock under load, and in some cases fuel dilution of the engine oil from an injector that is leaking internally. It costs little to confirm the diagnosis first. Compare return flow between cylinders and cut each injector in turn on a scan tool; if one cylinder makes no difference to running quality, that is your culprit. Before fitting: clean the seat thoroughly, use new copper washers and seals, and torque the clamp to the engine manufacturer’s figure. Replace as a set where possible, and check whether the ECU needs the new units’ classification codes written in afterwards. 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.
