What is injector pump calibration?
44,548 views • May 6, 2018 • Calibration includes replacement of O-rings, oil seals, cleaning and testing with a Machine if the injection pump functions accurately so it will be adjusted to the normal settings.
Do fuel pumps need calibration?
High pressure injection pumps, used in Diesel engines, are calibrated on a specialized test apparatus. Fuel pressure and volume, for each individual engine cylinder, are adjusted at specific speeds. Usually, this is only done if the injector pump has been repaired or rebuilt.
What is the difference between phasing and calibration?
What is phasing and calibration? Phasing means the action of dividing a large task or process into phases and calibration is one of the primary processes used to maintain instrument accuracy. Both are different. It’s necessary to calibrate the instruments.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.

What’s the pressure of a diesel injector pump?
Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
Is there a way to calibrate an injection pump?
This feature is not available right now. Please try again later. 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. Loading…
How to calibrate the mechanical diesel fuel injectors?
Adjusting the injector nozzle valve opening pressure is an easy operation, by installing the shims having the appropriate thickness to load the spring consequently. Marbed shim kits (9791, 9792 and 9372) consist of excellent quality pressure shims of different sizes as shown in the following images
