Anyone *rebuilding* the 6.4???

Rate this topic


Recommended Posts

So I've got an '08 F550 6.4 Dump truck with a lower end noise that, after removing the engine and pan and inspecting, was determined to be the result of the #8 rod bearing being heavily scored and gouged (along with the crank) and signs of it spinning/walking around in the rod itself.

 

Wonderful.

 

The delicious part is that I may actually end up putting a crank, bearings, and a rod/piston in this thing as opposed to just putting an engine in. It has 2,600 miles, it's still brand new. I can't imagine that the customer would be happy that a $70,000 truck this fresh would be getting a bottom-end overhaul instead of just being replaced.

 

Anyone here dealing with this?

I just did a crankshaft on one for the front snout being bent by .004". Cracked the oil pump cover, stretched the belt, and rattled the ever living snot out of the tensioner. 6.1 for cab R&R and 13.9 for a crank. I lost me arss. /forums/images/%%GRAEMLIN_URL%%/crybaby2.gif We don't have the proper engine stand for the job. /forums/images/%%GRAEMLIN_URL%%/crybaby2.gif /forums/images/%%GRAEMLIN_URL%%/mad.gif

We avoided one of our account's bringing in a 6.4 that hydrolocked. Happened 25miles away from us, they went to the closest dealer /forums/images/%%GRAEMLIN_URL%%/thumbup.gif....

I'm having to get prior approval on some really odd stuff, lately.... We have a 4R75 with significant metal in the pan and rancid fluid. We have to tear it down because the work order states that the truck will still move....

 

Needs a case, converter, OTA, valve body, solenoids... not to mention half the stack wont come apart.

 

I get the feeling that something is afoot in the warranty department.... and it prolly ain't gonna be pretty.

Fortunately we got ok'd to put a whole engine in this thing. My body is killing me though, we had no way to lift this thing and the amount of aftermarket garbage strewn threw this truck has bee nothing short of frightening. I hope to God that I actually get it back together correctly, lol..

We had a 6.4 with no compression on #2, they wanted us to pull the pan, and inspect why. Cyl #2 all scratched to hell. They wanted to know how deep the scratching was, and if we could hone it.

Is it just me or does it seem that they are tying to do everything humanly possible to patch these things as cheap as they can and keep their heads above water?

 

Between the warranty costs that are through the roof in expensive parts and intensive labour and the court cases and lawyer fees they keep trying to cheap out on repairs and cut our throats more and more every day on labour costs.

 

It's no wonder they are losing the backbone of this industry wich would be professional techs like everyone I hear from on this site.

 

Sorry for the highjack.

"Back in the day....", everything got repaired rather than replaced... If some guy lunch his engine and all you could save was a handful of oil pan bolts... you'd take those bolts and build a brand new engine around them... Needed bushings or field coils for a starter... order 'em up and fix it.

 

Yeah, replacing assemblies makes life easier and quicker.... but there's a lot of "art" being lost.

 

I'm waiting for a head for a 6.4.... and I'm surprised that they aren't having me just replace the valves.

Digging deep into areas of the memory bank that haven't been accessed for quite some time, I worked for a L/M dealer in the early 70s. At that time, many shops would opted for boring one cylinder oversize. Ford would not allow us to put any rebuilt pieces in a new car back then.

 

It makes us want to grit our teeth these days, but it was accepted industry practice at the time...

 

Disclaimer... from my foggy memory, it was a practice that was adopted early in the era of the automobile... By the early 70s, automotive machine shops were gaining ground and boring bars (the old ones that bolt to the deck of the block) were being foresaken in favour of rebuilt assemblies. It took many years for rebuilt starters, generators and such to become accepted by many customers.

 

Sorry for the hijack, guys...
