I have narrowed it down to be in the injector on number 4. On the inline injector pump... I have taken it as far as pulling the nipple assembly off the injector with the spring and jet looking thing. I'm getting fuel to there. Not sure about pressure. When I changed fuel filters, they were incredibly dirty. Has anyone here been deeper in an injector pump!?
 
Wow!! You learn fast!! I saw your question on where the engine valves were, & now you're disassembling injectors.
 
Are you sure it is the injector, or is it low pressure to the injector? Did you switch two injectors and see if the problem moved?
 
Check your oil and see how over full it is. If it been missing a long time it may have the oil may be thinned out. A bad seal in pump could cause that to.

Its low pressure to the injector, I compared it to another one . the one I believe not working, can't really see any fuel coming out.. The other is spraying all over. So with it running, I backed off the nipple assembly with the spring in it, started to spray fuel. Any more thoughts!?
 
My question was, where is the adjustments at. I've seen adjustments on push rods on the side of engines before and on rocker arms. Just didn't want to start taking off a bunch of covers that I didn't need to.
 
"L" Head or "Flat Head" Engines adjust on the side of the block. "Overhead" Valve Engines, such as your 900 & all CASE built engines, adjust @ the top, @ the rocker arms.
 
Sorry to say this but you are in dangerous teritory fooling with a injector. Have you ever realixed you can get injected with high pressure fuel an get blood poison by what you are doing? You are at
acting what you say is a problem entirely with out basic knowlege of how a Diesel operates an the DANGER you are facing.
