Speed Governor - Cummins S6700E/H is part of the fuel circuit: it delivers the flow and pressure the engine needs at each speed.
Any work on the injection circuit demands absolute cleanliness. A 5-micron particle in the high-pressure line damages the needle seat. Change the filter as well and purge the air before signing off.

- Always fit the new sealing washers and O-rings supplied with the component.

Frequently asked questions
Can injectors be cleaned instead of replaced?
If the problem is dirt and not wear, ultrasonic cleaning on a test bench restores flow. If needle or seat are damaged, no cleaning will fix it.
Why does the engine smoke black after an injector change?
Wrong calibration or air in the line. Verify bench calibration and purge the circuit before blaming anything else.
