Question QUESTION: Do I have to move the timing letters a, b,and c 360 degrees for each valve setting? Making a total of 6 moves.
ANSWER: No Felix. you need only two revolutions to complete the setting of the six cylinders.
If you start from A 1-6 vs you will adjust the corresponding injector and valve. Then move to B 2-5 vs and do the same, then to C 3-4 vs as well. you would have completed adjust on 3 injectors and three set of valves. You will move to A 1-6 vs on the second revolution to complete the remaining 3 cylinders of injector/valve setting.
You cannot adjust on TC (Top Dead center) mark, only on the vs marks.
If you still need further clarifications, pls. let me know.
Cheers.

QUESTION: Are the cylinders 1,2,3,4,5 and 6 or 1-6,2-5 and 3-4? This is a n-14 plus cummins engine.
Answer Cylinders in a 6 cylinder engine are numbered 1,2,3,4,5,and 6 from the front of engiine to the rear.
However, for the purpose of setting the valves and injectors, Cummins arranged the adjustment points in the order 1 and 6, 2 and 5, and 3 and 4 VS (valve setting points) These cylinder pairs have pistons that move together in accordance with the con rod journals arrangement of the crankshaft. i.e. Both pistons 1 and 6 are reciprocating in the same direction at the same time although on different strokes. For instance, as a 4 stroke cycle engine, if piston no 1 is on intake stroke, piston no 6 must be on compression stroke and vice versa. Same for the other remaining pairs in accordance with the standard firing order for N14, i.e. 1-5-3-6-2-4. this denotes the order at which injection and firing occurs in the engine assy.
Should you require further clarifications, pls. don't hesitate to write.
