i am trying to get as much info on the tone ring mod as possible every post i have read has kind of lead me in different directions about it. can any body help me out and explain how to do it or have pics?

 

I'm sure that you can find pix if you do a search. But it's very easy.

remove serpentine belt. Remove 4 bolts on dampner. Remove tone ring. Keeping the tone ring in the same direction as you took it off, remove material to the left side of the dowl pin locating hole, or just make it larger. Put the tone ring back on the same way that it came off, put the damper & bolts back on. Just snug up the bolts enough to rotate the tone ring clockwise as you are facing front to rear of the truck. Tighten bolts down, install belt & enjoy.

 

well i am heading out this morning and going to give it a shot. hope it is as easy as you say it is. thanks for the help

 

I always loosen the crank bolts before removing the belt. That way the belt keeps some tension on the pulley so it doesn't turn so easy. I have always had to use a long handled 1/2" drive ratchet and smack it with a 3lb hammer in order to break the bolts loose. I also use that method to "Torque" them back down when I'm done...

 

yeah that is what i did it so far so good. tone ring is done and now im looking for the silencer ring. any HeLP?

 

Is the tone ring mod noticable in performance?

 

i noticed a little bit more power at take off but not a lot. i am just aiming for MPG right now. got the silencer ring out and the fins out of the intake tube. sounds like a real cummins now

 

Any gain that you can actually feel, especially when it's free, is a great mod. The two thing most people see with this mod are a little better power off the line and better mileage.

This is more of a mod for an otherwise stock truck....

 

Thanks, I was just thinking about doing this temporarily until I get my Smarty SR. The truck is pretty sluggish since I pulled out the Smarty JR, I forgot how they run with stock programming.
