hole brush.

Ream injector body ring using injection body hand reamer (Figure 5, Item 29). Insert injection body
hand reamer in body and turn in clockwise direction a few turns. Then remove injection body hand
reamer and check face of ring for injection body hand reamer contact. Repeat operation until injection

of injector nut cause poor seating and result in fuel leakage around spray tip.

of injector nut (Figure 5, Item 6) to produce a clean uniform seat for spray tip.
