Injector shims

[Goteborg Vapenfabrik]

I found a formula for increasing opening pressure by increasing shim thickness through exhaustive internet searching once, I forgot where the information was as well as the formula. Stacking is allowed and probably the most economical route to 165 bar.

Lapping the wear surfaces of the injector is also recommended. You may be able to find a tutorial or video out there somewhere for the process.

Thanks for your help on this one. I'm using the Vince Walden tutorial recommend by Ngoma on here. I came across some info that might be what you found.

Any update about the shims?

I took apart three sets of injectors and
I am noticing two different shims, some have a larger hole than others. Will measure soon and post a picture...to show and compare. Can you interchange and/or mix those?
What`s the purpose of certain shims having a substantially smaller hole?
Is this in connection with how (how quickly or gradually) and when the pressure builds, at all?

Where do you guys get the shims? Any source online available or do I have to visit a junkyard with the 27/22/17mm tools ))
Usually I see no diesels either... not even a benz or a rabbit.

Different shim center hole size no functional difference, as long as it has one.
