803545387 is supplied as a remanufactured replacement injector. Cross-reference numbers: 803545387, 115300-3891, 15300389, XE75D80D. Application recorded for this part: Fits XCMG. Fuel is delivered to this injector already pressurised by the rail. What it contributes is timing and atomisation — opening and closing within milliseconds, several times per combustion event on modern engines. Small changes in spray pattern or opening behaviour show up quickly as noise, smoke and rising consumption. 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. Before replacing anything, distinguish injector faults from their look-alikes. Comparing return volume between cylinders and running a cut-out test on a diagnostic tool will show which cylinder is actually contributing — cheap checks that prevent replacing parts that were not faulty. Fit as a matched set rather than singly — one new injector among worn neighbours reproduces the uneven running you set out to cure. New sealing washers every time, clean seats, correct torque, and where applicable, program the injector codes into the ECU once fitted. 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.
