9320A344G is supplied as a remanufactured replacement injector. Cross-reference numbers: 9320A344G, 2644H023. 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. Symptoms that point to injector wear include hard starting when hot, rough idle, white smoke at start-up or black smoke under load, a sharp knocking from one cylinder, increased fuel consumption and a gradual loss of power. 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. Fitting notes: replace as a set rather than singly. A lone new injector will deliver differently from the worn ones around it, which usually reproduces the rough running. Use new sealing washers every time, clean the injector bore and seat carefully, and check whether your engine management expects classification codes to be entered after installation. What we do differently: every core is stripped to components, inspected against wear limits and measured before anything is reused. Worn parts are replaced, not cleaned and refitted. After reassembly the unit is bench-tested — delivery, return flow, opening pressure and leakage — and only units inside specification are dispatched. We can send the test sheet for your order before it leaves. Every remanufactured unit carries a 12-month warranty.
