We never would turn work away. The way they adjusted it was jsut to not pay us for labor operations. Mainly diagnosis. All we would get would be engine performance diag and then the part. He thought he knew how to manipulate the numbers but it got us in big trouble. This is a full audit. Not a mini one.

Hi Brad

 

I work in an indy shop, and we got a call from the Ford store we buy our parts from.

 

They had 2 6.0s that supposedly needed head gaskets, and they wanted to farm them out. I asked details from the parts guy who was fishing for the service department. One was customer pay, and the other is warranty. They would pay us to do it.

 

How exactly does that work?

 

It sure seems odd that a dealer that's dead also, is farming out 6.0 work. They won't even touch 6.4s except for oil changes. They say they are diesel "certified".

 

My boss in his idiocy turned them away.

The screwy thing about the 126 is it compares dealers in like markets to each other. ( grading on a curve ?) So if EVERYBODYS 126 is bad, then who's fudging the numbers. Can only be the guy writing the 126. I think they are trying to scare us into reducing warranty costs.

As for engine blocks... we don't have a cylinder bore guage for checking out of round and taper... we don't have any means of fitting pistons correctly (if a piston is snug, a deglazing hone is going to be a slow and inaccurate way of making it fit.... What is also interesting is that they give a piston to wall clearance spec but they forget to remind you of how to properly measure it (90 degrees to the pin, room temp with a pull gauge).

 

For further clarification, consult the WSM 303-01C "General Procedures". Pay close attention to the sections marked "block distortion" (they will have you measure for deck flatness... usually not a big concern), "Cylinder bore out of round" (important to notice that they don't tell you to check for cylinder taper but there IS a spec for it)...

 

The one last thing that never seems to get considered is crankshaft deflection... #8 appears to be the bent rod king of the 6.4... It's running mate is (IIRC) cylinder 3 (my diesel experience is waning). Yes, the crank is one beefy mo-fo in the 6.4... but that doesn't mean squat in the grand scheme of things. We need to compare TDC on both of these cylinders to be sure we aren't going to run into a gotcha - might be imperceptible... might be a heart breaker.

 

Now... the crank in the 6.4 is forged... but that is an open ended statement... (I don't see anyone calling it a forged billet crankshaft so we can rule that out). So.. does the crank start out flat and get twisted to 90 degree throws or is it built as a four cornered crank? FWIW, crankshaft construction is a fascinating subject... and worthy of more than us saying "DUH... d'at's a crank..".

Disclaimer...crankshaft twist is something that occured to me as I sat pondering this post so I have no prior knowledge on which to base my assumptions... Could this be something even the engineers have overlooked?

There are specs for all of these things related to cylinder clearances and crank specs, unfortunately most of these are specs that machine shops have and use daily. It may be worth while to check with your local crank grinders and machine shops for assistance with these. Michigan Cat, Cummins Bridgeway, and W.W. Williams Detroit use us all the time to check heads,blocks,cranks,turbochargers and injection systems. In the long run it's cheaper for them to do this than to chance the rejected claims due to being wrong. We have a guy we use and have used for many years to install repair sleeves in dry blocks. Saves a ton of money and he usually will come to your location to do the job. It may be something to check out if warranty numbers are way up. It's a good permanent fix and will save your shop some serious claim numbers not to mention save on customer pay jobs.

The only problem with that is, they won't likely pay the claim if it's repaired by sleeving it -- since that's not listed in the fucking workshop manual...

But some dealers are willing to sub the jobs out?????? Why wouldn't you fudge some ops to get the job done?????

 

I was a Cummins and M-59 Dodge sent us all of their ISB warranty work, on a sub basis.

 

Why couldn't this work here???? Ok Jim tell me......

 

It's done everyday....
