Advice Breaking in rebuilt 6V92?

[rsmith]

GE makes big turbines. They have year long "factory training". GE used to be GREAT...until all the great people that made them great gave the bean counters and Jack Welch the finger.

Now the running joke is,: "GE, we probably aren't the best, but you can be sure we're the most expensive!" and "GE, Imagine it works."

The small biz guy can't afford to have unhappy customers. DD "factory shops" can afford to piss off customers. It's pretty simple.

I'm with krush on this one. Now old jiffy jeffry Imelts giving all the stockholders the finger

One good thing that can be said for the DD dealer is that if you use them for a rebuild, you DO get a warranty and they WILL honor it. Some of the little guys may warrant their work, but they may not have deep enough pockets when everything goes to hell.

Example: I had a big CAT engine in a 100K lbs front-end loader rebuilt by CAT. On the second day after getting it back, it put a rod through the side of the block. As it turned out, someone forgot to torque the rod bearing caps. The end result is that Cat put in a new rebuilt engine. I have no idea what this cost, but I'm sure it wasn't cheap.

Obviously, the chances of having this kind of a problem from a big shop with several mechanics working on the same engine is higher than with the one man show. But, what would happen if you had a major failure like this under the warranty period for your rebuild on the boat? And what if it ruined the block and it was documented to be the rebuilders fault that caused it, AND it was in a MY that had to have the side of the hull cut out to get the block out? What then? I'll tell you what. They had better have some deep pockets and some good customer service.

Sometimes the cheapest price is not the only thing that matters.

Point taken, but that's the reason for shop liability insurance. I'm sure the Cat dealer used it in Your senario.

Only two men should be responsible for one rebuilt motor, the builder who should also be the installer and the machinest. To Not torque rod bolts is inexcusable, I find it very telling to know just who that tech worked for.

EDIT: Another thing, that tech should have sold his tools, because the only tool he'd need at his next job would be a microphone headset, saying "Would You like Me to Supersize that order?"

Do Detroit Diesel manuals have advice on break in after rebuild??

I don't believe I ever checked and my manuals went with the boat.

OK, where the mechanice DD trained? I just had to ask.

Just to add to the discussion of factory trained versus experience taught, here is my story. When I decided on the boat I wanted (48 LRC), before finding and buying one, I went to the 53 series DD "factory training center" at Covington Diesel in Greensboro, NC for their 53 Series rebuild class. Completed the class, got the Certification Certificate. Finally found the right boat, year later decided to rebuild the 453 engines and hired a small business guy who had been doing Detroit rebuilds for 25 years to do it. I was his helper, learned a lot, engines have run 10 years without a single problem. Trust me, you would rather have this small business guy do your rebuild than me, I made that same decision, and I was "Factory Trained and Certified".
