5347134 is supplied as a remanufactured replacement common rail injector. Cross-reference numbers: 5347134, 2897320. Application recorded for this part: Fits Cummins — ISF2.8. An injector is a high-speed valve. It has to hold back rail pressure, then open and close within a fraction of a crankshaft degree — several times per cycle on pilot-injection engines. Anything that alters opening behaviour, whether it is carbon on the tip, a worn needle or a tired solenoid, changes how the cylinder burns its charge. What owners usually notice first: longer cranking, a rougher idle, more smoke than the engine used to produce, worse consumption, and occasionally a metallic knock that appears under load and clears once the engine is revved. 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. 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. 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.
