I was looking for the thread about fuel screw bottoming out before runaway comes up as broken link.

 

That's a hazard of linking to stuff on other sites. Looks like the group who posted it is no longer a part of the site it was hosted on.

 

im sure somebody saved the webpage and can copy it on here... or is that copywrite complications????

 

well i'm guessing some of you have run in to that problem what do i do about it.

 

All he did was make his screw longer by adding about 1/8" to the end by welding a small bead on the end. He then rounded it off and made it smooth like the original. I he also said he had one end in a small cup of water as a heat sink.

I believe that cummins makes a longer fuel screw without a collar for <$10 I'm told. I heard this on a separate thread, so someone might have a part number for it. I'll need one in my 93 as well.

 

thats the funny part the screw doesnt seem like it threads in very far before it bottoms out i have lots of screw still sticking out.i was thinking it might be an internal problem

 

I've got an extra one of the longer fuel screws handy.

 

Fast59, are your threads all good from removing the collar? I don't know if there is a shoulder that bottoms out or something. When they lengthen it, it's just on the tip. I haven't looked at a power screw in a year or two, I've forgotten exactly what it looks like in every detail.

John, you don't happen to have a part number on that do you? I need to order one.

 

well i have not pulled it out yet but the jam nut can spin off the end of the screw so i dont think threads are the problem it just feels like it hit bottom and just to add i was the one that removed the lock collar and originally only gave it about a half turn.

 

mine is TIGHT as a spring chicken ;-) I think the combination of pressure and years of being in the same spot might have something to do with it.

 

I thought that to but i just dont feel right about just cranking on it.

 

DO NOT CRANK ON IT !!!!!!!!! If you pull it out you will see that there is a spot in the middle of the screw that is not threaded. The threads do not go continuously from end to end. I had the same exact issue I had to lengthen the rod 3/16" or so with weld. Then I found the runaway!!!

 

I took the collar off and easily found runaway with plenty of screw still left to go in

so all of www.dens-site.com is gone ??? thats alot of good stickies. DANG!

 

recoils of a bad economy....
or ripple effect if you may

 

I'll go out right now and pull the screw and see whats up.thank's
