Injection pump calibration includes replacement of O-rings, oil seals, cleaning and testing with a Test Machine if the injection pump functions accurately so it will be adjusted to the normal settings.
What’s the Purpose of Injection Pump Calibration
Why do you need to calibrate your diesel injection pump?
Try to observe if you notice the following most common symptoms of diesel engine problems that may be attributed to the fuel equipment, the injection pump, and the nozzles:
- black smoke
- high fuel consumption
- inadequate power
- hard starting
- noise knocking uneven
- rough or unsteady idling
- engine overheating
- high engine oil consumption, and
- failure of starter to crank.
When any of the above is observed, the injection pump must be brought to a qualified fuel injection equipment repair and service shop for a thorough diagnosis and for fuel injection pump calibration.
The proper diagnosis of the diesel injection pump is not to be done by a mechanic, but a calibration shop unless the mechanic owns one. The reason is that repair and servicing require high technical expertise and a test machine needed.
It is like a heart bypass that should be administered by a doctor who specialized in heart operations with all the technical tools to handle it.
