About this part
131-852N is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 131-852N, 3280772, 3280567, 0-432-131-852N. Application recorded for this part: Fits Cummins — (3280772; 3280567) 5.9L.
In a common rail system the injector is the component that actually controls combustion. It holds back fuel at rail pressure and lifts for only a few milliseconds at a time, metering the exact quantity and breaking it into a fine spray so the charge ignites cleanly. When delivery drifts, the engine does not usually stop — it simply starts to burn fuel badly.
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.
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.
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.
