There are a few colors of solenoids in the wild; black brown and yellow. The color doesn't matter as long as the solenoids have the proper resistance and inductance.
We use the magic of ultrasonics to clean the injectors after disassembly. During assembly we use isopropyl alcohol, calibration fluid and clean dry compressed air. We have a new ultrasonic unit being manufactured that will greatly help our cleaning station. They tell me it'll use up to 19,000 watts of 240v 😱
Is this a recent thing or years? I ask because I bought a set of new AC a year or two back and now you got me wondering if a ****ery like that is lingering on my AC codes.
We are wondering now if the new AC injector we order some years ago that only flowed ~50cc was actually an AA injector. This is rare case I hypothesize. Maybe @DZL JIM will chime in on his new injector findings.
These are stock replacement injectors designed (or expected) to be be used in stock applications where injector emptying is not a thing. Remember, AA and AC is only a piston machining difference and it only takes 90 (on stock tuning) to get 215 flywheel horsepower....which is almost where most "HT" medium-duty trucks were too at the time.
So how do you clean the parts before storing them here? Ye olde solvent tank and a brush?
I bought a Pro Ultrasonic tank about 7 years ago. After a year of messing with it we gave up. We went back to using diesel fuel and a scrub brush in a wash tank, nothing beats good old man power. This cleans 10x better than the ultrasonic ever tank did. Change the 2 gallon tank every week or so for what used to be only a few dollars and move on. The parts stay wet with fuel and don't dry out, and clean right up during our other processes.

The thing is, I rarely sell new injectors, maybe a few sets a year, and almost always drop shipped to the customer because they are stock, and why not? Of the few of the sets we got in house for upgrades we have seen mixed Pistons, plungers in the the wrong barrels, wrong barrels with the correct plungers, barrels missing check ***** and bands, etc. A very high percentage of what we have worked on had weird issues like this for the few we actually take apart. Makes you wonder. Not to mention tolerances that a high performance injector will never hold oil pressure with.
With the high cost of a new set I really don't expect to sell them ever again. I'll gladly talk a customer into rebuilding a 300,000 mile set instead of sell a new set any day anyway.
Naa they ran perfect, just that return to idle nonsense, the 180/30 do the same. It is tuning, only one tuner can het it out, but the shifting from them is baaaad. The AD30 were great in all manners, cant wait to get them back in with new unclogged nozzles
I don't understand this. Maybe you need to visit the PHP school and live tune your truck.
Aint no way. Its dialed in with the ad30, thats all I care. Done messing with it, I have one more last project to complete here soon, then hanging my hobby hat up, driving it, and only doing needed maintenance. In ten years if I need another I will buy a 6.7 and leave it stock. Its time to reduce my busy time, and invest what time I have into enjoying life my wife and kids and doing things they like.
All the php files and tuners that use their base files or similar have the issue with singles in this truck, so php school may not help me. Plus it would be cheaper to fly a guy out to my place to live tune it then waste my time screwing around learning how to do it.

This has been my goal along with efficiency, reliability and longevity with my truck. I am fortunate to have met that goal and the truck is a tow pig that I perform regular maintenance on and just drive it.
It is a freeing feeling knowing when enough is enough from within.
