Thanks Hunter, That last link has the picture that identifies the bolt. I had also gone out to take some pictures of mine. The first picture is the dampener bolt, right - it is silver. It doesn't look like there would be much room to get it out because of the oil filter housing but apparently there is.

What's this bolt in the second picture? This is what I thought I was looking for until I saw the picture in Hunter's post. It's on the driver side of the injection pump and looks like it is some kind of adjustment bolt.

First time to post pictures - hope it works

That second bolt is where you lock the IP in place for removal. It's also where you plug in the A-B timing light to check timing.

It hasn't been said in that many words, but I think they are suggesting I should replace the rack dampener bolt first.

Yes, I would try adjusting or updating your rack damper pin before you try new injectors. I have a similar hot idle shake on my SD, and I will be installing some of my rebuilt injectors in it soon. I'll let you know if they change anything.

If you decide to have me rebuild your injectors you don't need to buy a spare set of injectors to send me, you can just pay a core fee that I will refund when you return your old injectors.

Does that part number indicate that is the part for a 601 engine?
Is the part for a 617 the same?

Ok, so I'm getting ready to rebuild my first set of injectors (tried getting some "good" used ones, NOT happy)

How do I (or where do I get) shims to increase/decrease pop pressure? I know there is a shim, but don't know how to adjust the pressure once the new nozzle has been installed (Bosio)

Maybe it's not necissary, but if I'm going to go to the trouble of replacing the nozzles I'd like to make sure they are all as balanced as possible and all at 115 bar.

Thanks
