BX25 fuel injector clean. BX24, BX25D, BX23S. With D902 Diesel Engine.

EDIT: I may have messed up: The upper part of the injector contains the spring, but none of the three injectors were willing to release the spring, and I did not try, as I did not know this assembly comes apart. Perhaps I will have to revisit my injectors.


After 2,900 hours, the engine was idling rough, and I assumed probably the fuel injectors required servicing.

My next step, as I am getting another slower rpm issue will be adjusting the valves. Video to follow, if I can't find a good one already on YouTube.
