I feel like this is a stupid question.
Where are the torque specs for X15 injector and jakes for an overhead?
I was looking for the spacing tools to do mine, when I read that these engines don't do that; everything has a specific torque spec and we move on with our lives. But every model/year/base has different specs that are published... somewhere?

I don’t think the injectors have an adjustment at all. The fuel system is different from your x15 (single cam) to an older twin cam. If you wanna adjust over head & Jake’s go to quick serve.Cummins .com. Create a free account. Put in your engine serial number and it will give u a step by step how to for free. Torque specs should be included

Sweet. I have an account on the Cummins site for checking part numbers, but that was the detail I was missing. Quickserve it is. Thank you much.
