Why Unit Injectors Are Replaced
On a unit injector the control valve and nozzle wear with running hours, so the injected quantity drifts from the value the ECU expects. Operators notice hard starting, a rough idle, falling power and black smoke, and the ECU eventually stores a correction-limit fault.
Fitting Notes
- Confirm the number on the original unit before ordering; unit injectors are matched to the engine variant.
- Renew the copper washer and O-rings and keep the injector bore clean.
- Recode the injector where the engine management requires it.
