as you can see, my machine says it's a D5K, but when you put the serial number on the Caterpillar website, it identifies it as d5k2. Now I have a problem with the injectors on my machine and I don't know which one is correct. What is the difference between the 2 machines?

Are you trying to identify the correct injector Part Number.?
From what I can see the correct P/N based on your engine Serial Number is 449-3315.

yes i don't know which one is correct. since vin says it's d5k2, but the nameplate just says d5k. The nozzles seem to have different codes. D5K 320-0677 / D5K2 449-3315
I don't know what the difference is between them so I can use one of these injectors.

I don't think that makes a difference. I have worked with D10T2 tractors recently and the VIN plate on them is only stamped D10T (not D10T2) just like your D5K.
I was looking at your other thread regarding adjusting the valves. You said the engine S/N is ********.
Looking in the online system your D5K2 S/N******** shows the engine Serial Number to be ********.
Can you confirm the correct engine S/N please.?

the correct one is ********. did you type right in the system? if so, I'll find out when it's on the machine.
the ECU reading contained the same number as the nameplate.

Here are the complete details of the machine S/N ******** and engine S/N clearly listed as*********.
Is there any chance that the engine ECM might have been interchanged with one from another machine.?

OK, based on the information available online - here's what I think.
Your tractor D5K2, Serial Number ******** (built May 2016) has had the engine replaced by one that was originally installed in a D5K "Series I" tractor of Serial Number ******** (built July 2011). See below.....

The correct fuel injector nozzles for engine Serial Number ******** (as it was originally built) are Part Number 320-0680.

Is there an echo in here.....?
Something else makes me suspicious.........
Look closely at the photo of the engine Serial Number plate in post #7 above.
There is an area much larger than the plate that appears at some time has had adhesive on it. I wonder if that location originally had a much larger plate on it with different data. Because the "engine plate" in the photo doesn't have the same amount of information that it would normally have. And, for example, it would not normally have "D5K" (machine model) on it, it would have the engine model (C4.4, but NOT "C4.4E"). I can't recall ever seeing the machine model on the engine S/N plate.
Here's another twist. If you look up the 187-8016 Arrangement Number in TMI it corresponds to an engine with mechanical injection, not electronic.........
This story is starting to smell like week-old fish................

Taken from one of the OP's photos. Hello, what's this..? I don't think that's genuine.
Also why would the 254-9233 engine Arrangment Number be different on the PIN plate to the 186-8016 that is shown on the (alleged) engine Serial Number plate.?
I am now convinced this is a machine with adulterated Serial Number plates on it.

The machine Serial Number should be stamped on the rear LH upper corner of the machine frame. However if someone has gone to the trouble of changing the identity of this machine they might well have ground off the stamped number on the frame.
I can't think of anything that would be quick. Is there a data plate on the turbocharger with a Part Number.?

Take a good look down in the centre of the turbocharger as indicated by the arrow. Is there a small plate with a Part Number on it.? You are looking for something like the illustration below marked "Caterpillar Turbocharger" and a Part Number. I know the plate shows a Reman turbo but it is the best illustration I could find quickly.
can you pull the serial number from the machine with this engine number?
I will check

Yes, the details are shown in Post #8 above.
The tractor in which engine S/N ******** was originally installed is a D5K of S/N ********. Built in 2011.
