If the tolerance is lost between the nozzle and guide, the pintle will stick open, foreign debris is often the cause. Removing material from the upper edge of the needle guide, also known as the stroke-limiting collar, will increase the allowable vertical movement. The pintle tip can also be ground to increase the dead volume in the nozzle tip if in a VCO style, or blind-hole if in a Sac style. Marker - part name Black - pintle seat Red - sac/blind-hole http://photos-b.ak.fbcdn.net/hphotos..._3845296_n.jpg This picture shows a closer view of the tip style, this particular nozzle is a Sac style with cylindrical blind-hole. |

There will be notes, when I get some more time...It may get a bit technical. What injector are you showing torn apart?. |
Spare body I had laying around, but somehow I think you are interested in the nozzle, it is from a Cummins 5.9L application, soon to be sporting 8 spray orifices.
