M7060 - Injector Troubleshooting/Replacement-DIY?

[tho2nd]

Good day everyone,

2019 M7060 - 860hrs

I'm in the process of chasing down a problem with my engine bogging down when at operating temperature and under a load.

I think I've addressed the easier first steps (new fuel filters, verified supply pump pressure, cleaned screen in water separator, new hydraulic filters/fluid). I also repaired an internal linkage for the draft control hoping that could be the cause.

Still bogging down.

During this troubleshooting phase, I've had a few folks on this forum refer me to the service bulletin that identifies failing injectors. My tractor and serial number fall within the range of affected equipment.....but it's out of warranty.

Two question at this point:

• Will Diagmaster pick up on past performance.......if the injectors are the culprit, will the diagnostic software see when they failed, or does Diagmaster need to see the symptom in real time?

• If I do need to replace injectors, what's the consensus on a DIY job (assuming average to a little above average mechanical skills) ?

Thank you,

TH

Some codes are stored, but an injector issue will show up even if it's not having the symptoms at present.

They don't use diagmaster anymore, it's obsolete, they have a new reader and software.
They use KOBD ACE, to do the reading and programming.

Yes you can blindly and randomly replace parts like the injectors.
But it's not really a DYI job, because you can't program the injectors.

Kubota has stated that if the unit is within the model serial number and is exhibiting a power loss after the engine gets to operating temperature, replace the injectors.
We have had customers replace their injectors and bring the unit in to program the injector codes onto the ECU. Pictures have to be taken of the codes on each injector prior to installation and also need to know which cylinder each injector was placed in.

Thanks for the info. Will the tractor run before the injectors are programmed?

Yes, but it should not be run any longer than it takes to drive it onto a trailer.
