It would be easy enough to add, and would interesting to watch, and....... some ecms (between the ears) might make adjustments accordingly!

1995 Caterpillar 3406E Engine Control Module (ECM) For Sale | Lakefield, ON, Canada | CAT95-2108-ECM-BSM | MyLittleSalesman.com
Maybe I'm a little confused.
Maybe not. I'll try to back of a little on my medication.
It might help my focus. Who knows.
I know that changing that sensor on a 1996 CAT 3406B fixed that pesky problem.
It was very hard to find it too. But if 1995 he has is that much different... -
With the overlap and many just make the reference 3406 it’s easy to do. Be confused I meanspsauerland, LameMule, AModelCat and 1 other person Thank this. -
Sorry. Should I back of my medication too? LOL. /s -

I tried to post pic of back of the pump. To check for full rack you put the test light on the threaded stud at bottom right side nest to block? If so it never lite up the tester before governor caught it.
What’s next step with that?
Also pulled elbow of exhaust side of turbo and it looks perfect.wore out and Another Canadian driver Thank this. -
Ok after a little more checking today i did find some boost leaks.
I pressured up the system the way @wore out said. I found a pretty good leak at one intercooler clamp and i hate to say also found a hole wore in the line going to boost gauge. Also found a leak around one bolt on the elbow to intake manifold and some very small leaks at a few intake gasket to the head, i put the gaskets on dry guess i should have used a little rtv on them?
Maybe these fixes will help some. Still curios about the rack getting full travel?wore out and Another Canadian driver Thank this. -
Don’t use RTV in those intake gaskets. The heat will cook it lol. Just get a smooth clean surface, the gasket will have a slight lip it goes up. Snug the bolts then start in middle working your way out to 40 ftlbs
spsauerland, Oxbow and rs72z Thank this. -
What do you think about the full rack travel issue, if i was even did it right checking it. -
There is a guide that goes under the torque spring pac. It’s sticks way off over to that side. It could be bent, missing etc. either way it’s a pull the rear housing off at this point. I have a cut away govnor housing I use to look at it.
you did put the test light clamp to positive right not ground?Oxbow Thanks this.
