12V135 is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 12V135. Application recorded for this part: Fits Yuchai — 12. 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. Typical signs are poor starting hot or cold depending on whether the unit is weeping or sticking, an idle that hunts or sounds uneven, smoke under acceleration, and sometimes a smell of diesel in the oil where an injector is leaking internally. A back-leakage comparison across the set is the cheapest meaningful test: uneven return between cylinders points at the failing unit. Follow it with a cut-out test to confirm which cylinder actually stops contributing. Fitment notes: injectors on the same engine wear together. Replacing only the failed unit often leaves the others close behind, and a single new injector reading differently from its neighbours will cause exactly the rough running you were trying to fix. Replacing as a matched set avoids that. Always fit new copper sealing washers and seals — used washers rarely seal a second time — and where the system requires injector classification or IQA codes, have them programmed to the ECU after fitting. 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.
