As far as I know it does not have the moving gubbins inside it which seize especially on a tractor that’s not worked hard Every day. Derv doctor would be worth a phone call look on Facebook etc,
JD 7530 injectors @ 3800hrs .. really

You must have better fuel supplies than around here then.Have you ever had your injectors tested?
To see how how worn they are, simple pressure test would tell you.
But there's no faults as in running rough etc tractor pulls like a train doesn't smoke or owt daft so why test something there's nothing wrong with

had all the same issues on claas tractors that we had, there prone to dropping a valve as well and that will trash the complete engine, thankfully wehad warranty cover on all the claas tractors simply because of the engines known history, run all masseys now as got fed up with the down time, engine is faultless and better on fuel as well
That’s fine if your happy with it then don’t worry about it, you may find that they are down on pressure if you test them. I know somebody who had a injector stick open and melt a piston that’s all,they never had any reason to fault the injectors but they were worn and down on pressure.

They can now but dealers highly recommended it a few years ago before the sulfur was reduced.
Back then I had a 6920 that would misfire etc unless it was being worked hard additive did bugger all to it just needed to be pushed on

You've plenty time left, we had a few over 9000 hours and one at 12500 without injectors.

Not had injectors in mine - just a new engine at 5500 hrs. Friend had the same with his 7430.

Same here, never had an injector replacement on any off our deeres, all dun 16k hrs then moved on, last 6830 is 12 plate with 11000 hrs , only had a turbo replacement in that time.

Our 6630 is on 7000h also and never had injector problems. Head gasket went on 3000h and rear end blew on 4000h.

Who’s diagnosing all these injector faults dealer/man in van? And how are they been tested, I’m quite curious
. I’ve customers with teen’s of thousands of hours on 20/30 series all still on a there original injectors!
Are they been replaced due to the 1347.07 code? Or is a full injector return test been done?

1347.07 - “fuel rail pressure miss match” the rail pressure is 50psi above or below the commanded pressure.
There is a lot of thing that can cause this code though from electrical, mechanical, and fuel. Unfortunately some people jump to the conclusion that the injectors are knackered!
Ps - you’ll usually also get 1569.31 which is engine derate.

Now Then..
I've rarely changed injectors despite the negative comments on here. As mentioned, who's doing the diagnostics??
Also rare is the seal failure inside a turbocharger. The actuator fails or the variable vane department, but oil leaking?? Is it not a badly installed oil line after the head gasket replacement?? There's an installation sequence for the injectors too..

Do you have any codes relating to the fuel system??
As for the test. You need to collect leak off fuel from the injectors. The pipework varies slightly so take a look and work out the easiest way.

I dont have any codes but lets say that the tractor has little different sound. Then it shows on injector test 40ml more than desired on few of them. Doesnt that mean injectors are bad ?
In most cases it does. Confirming it also by the sound when you turn them off while testing. If the sound is worse when one is off then that one is ok. The smaller the difference in the sound the worst the injector is.
Those ml show leak off injector.
