Cm2250 overhead set

[JMBT]

I don’t have a link, I just put the dial on the back side of the Jake rocker and zero it out, then push it down into the detent position. Measure the travel .000 of a inch, write it down, then at the next overhead take another measurement to see how much if any detent you have lost.

You are correct it is not in the Cummins manual, but then again they also say when the detent is gone you can slightly rotate the rocker shaft to regain it.....that is a huge no, no! I think Rawze posted about it once. No detent means the valves are to high in their seats and the head is worn out, but Cummins fails to tell you that too.
