Pop the hood look on the valve cover. Probably 6.4

I agree it's probably a 6.4 Catubishi engine.

Thanks for reply ....
They sent those photo from desert and I'am still at home, so they need to change the injectors ... via my Cat II adapter for trim files .... my questions
1- Do i need to adjust the new injectors after replacement .
2- Do i need to do valve lash .
3- Do i need to dismantling the rocker arms when changing the injectors.
Thanks Gents

Engine for machine S/N KGF04007 is a C6.4.
There is no electronic code adjustment for this particular type of injector as far as I know.
Valve lash should not be affected by replacing the injectors (unless someone does not follow procedure that is). The injectors can be removed through the gap in between the two rocker arms.
You do not need to touch the valve operating mechanism to replace injectors. See photo. Remove the 2 nuts #2 and move the wiring harness #1 out of the way. Remove the hold-down bolt #3 & remove clamp #5 (not shown in the photo). An angled pry bar can then be used to remove the injector. Make sure the injector bore in the cylinder head is thoroughly cleaned before installing the replacement injectors.

Easy way to tell. C6.6 has common rail pump on left hand side of engine
C6.4 has common rail fuel pump on right hand side of engine

Hi Gents,
Thanks for support… the job done and the excavator working fine.
I tried to start the engine before replacing the injectors… the fuel rail pressure was 3485 PSI But I couldn't start the engine
I tried by force duo to spray gasoline from Air filter ,the result of delivered fuel volume mm3 cutout test was (26.0 ,25.9 ,25.8 ,25.6 ,25.5 mm3 )... The problem I found after removing the Injectors the trimming files is not matching with the injectors …. I asked the owner of Excavator how changed the injectors last time?
He said one of my friend ,but it wasn't want to start ,I contacted with dealer and he came to program the injectors.
Gents.... actually the dealer guy fooled the owner that he change the trim files but no, he was Indian guy and he is lazy ... With the new Injectors working perfect and cutout test result just for reference the delivered fuel volume mm3 (22.8, 22.7, 22.7 ,22.5, 22.3 , 22.2 mm3).
Do you think guys 2 mm3 and the injectors needle was dirty with black scales it makes different.

Thanks a lot.
