Small linear actuators???
Seems like a LOT of work when the answers allways gunna be a different eng.

Stepper motor?Small linear actuators???
The torque screw basically is an adjustable stop for the metering valve, limiting how much fuel can get through the mv and into the charging ports in the head.
I'm looking forward to that thread [emoji6]The lock nut has to stay to retain the o ring against the housing and seal the torque screw. Y’all can experiment with electric control if you like, but I plan to keep electronics off my db2s indefinitely. It would be more difficult to do with the smaller pumps like 90 and 110s because of the retained light load advance but locked timing pumps I have external controls available for anyone who wants to have the ability to adjust power on the fly with my 130 and larger pumps, all done mechanically with control in the cab. We are going to be showcasing it on a project I’ll be making a thread for once it hits the dyno.

I wasn’t saying anything electronically controlled at all. I think I should’ve explained that better. I mean like a literal mechanically controlled rotary thing so you can just turn the screw from in the cab .Small linear actuators???

Yes, and the adjustment is good for hot pumps where daily driving with 400+cc is not warranted, but needed when the Cummins bros need a lesson.So this let's you turn the fuel up or down? Is there a reason not to set it high and leave it there? We could come up with a sane way to control that screw from inside the cab, but I'm not sure why we'd want to.

Does this mean that you won't be working on any 94+ 6.5 pumps?I plan to keep electronics off my db2s indefinitely
That’s very good, although turning the pumps fuel delivery up won’t have any negative affects for reliability, in fact you can often cheat a bit more life out of a worn pump by turning the fuel up. Your high idle issue is likely unrelated to the pump, it’s probably an issue with your high idle solenoid, if it’s getting erratic I sell them on my website.
It’s this type of thinking that’s held these engines back...Small linear actuators???

Put a big toothed wheel on the end of the screw, turn it with a worm that is twisted by a cable or linkage with the other end mounted on the dash. From what Wes is saying, we'd have to come up with some other way to seal that penetration, and that would be the difficult bit.I wasn’t saying anything electronically controlled at all.
