No shit i started in cnc machining. Irrelevant but wanna ask because its crissed my mind before, how hard is it to learn as a trade? Ive seen local tractor/agg suppliers qlmost constantly looking and im able to tear down and rebuild mazaks and feel like diesel engine repair wouldnt be any more difficult than that. Would it be something a place would do as on the job training or is this something that needs to be trained at a cert school/trade school?

Ultimately it shouldn’t be significantly any more difficult than servicing or rebuilding any other engine, but with diesels, there’s a huge safety factor to consider, called diesel engine runaway.

Diesel doesn’t use spark plugs, so there are conditions where if everything isn’t running right, you can’t shut the engine down, and it could ultimately either explode, or drive away uncontrolled if still in gear.

So, lesson number one of working on a diesel is to know how to shut it off in an emergency. Since it doesn’t use spark plugs, then turning the key off is no guarantee that the engine will stop. You have to know how to either stop the fuel supply, or starve the air intake.
