I've been searching but can seem to find anything. How exactly do I get a screwdriver in that space to mess with my full power screw. I plan on backing it all the way out to take the collar off, how?!

 

On the intercooled trucks you can use a 6mm socket and a ratchet.

 

so im basically just loosening the jambnut then?

thanks wannadiesel, your the man.

 

Loosen the jamnut with a 13 mm wrench , then use the 6mm socket to back the screw out.

 

So how do I do it on my non-intercooled truck?

Where's the love?

 

You gotta work a screwdriver in there somehow, Begle. Nobody at Bosch loves you.

 

If I remember correct, an open-end 12mm wrench and a long shaft straight screwdriver of medium size.

The open-end wrench works the lock-nut and the screwdriver adjusts the fuel screw.

 

Why in the world would you want to do that ?

 

see the big picture loch, take it out and get that pesky collar off... then you can really have some fun!

begle- i have a screwdriver that's about 12-14inch long that i slide up from the back, works great!

 

I guess that collar you are talking about is the copper washer-looking thing that the Cummins Nut handed me and said "hang on to this, we may have to put it back on."

My truck would lunge out from under me at the slightest application of throttle and I could break traction in high gear ; but, the pyro would peg on the slightest grade with no trailer.

I backed it off one and a half turns and, while not hardly so wicked, I can pull the big trailers and live with it.

 

Mine just kinda fell off when I was pickin at the bugger.

How much should it be turned it just enough to tease you but not enough to make smoke?
Remember I am in California.

I am going to pull it out and run a die to clean up the threads.

Jim, in non intercooled truck you cant get much without smoke, ours have lot bigger injectors than intercooled trucks. Just try one round and punch it to check out the smoke.

 

Can't be sure because the collar was gone, but after cleaning up the threads by just running the locknut back and forth on it with some WD-40, I counted threads and put it back in with what looked liked about 2 more turns in and it was too much for me! Lotsa smoke and power. Backed out a turn and stayed there. Noticeable power, a little more smoke. So I'd say I couldn't get much without smoke either. Starting to wonder what injectors might be in this thing.

 

i've went in 2 turns and liked the adjustment.can somebody tell me if you can do more than 2 turns without doing damage?

 

thanks for all the help guys. I took the whole screw out and broke off the collar, doing my best to keep the jambnut in the same spot. I put it back in and turned it probably half a turn at best, then tested it for today as it was getting dark outside last night when I was working on it. Well, I went out again today and gave it another half twist. Gonna see what happens, then might add one more then I'm done. I swear!

Sure like the little puff of soot she throws out when I blip the throttle!
