Deranged rebuild, the next chapter

[Cutting-Edge Diesel]

Hoping so, I have a spare crank if not.

 

[Mwilbur516]

Good to see you taking it all in stride.

 

[Dalpilot]

It got hot then. That looks like it can be turned.

 

[Extended Power]

Least your rods didn't turn to a blue color...

 

[Craig@MFI]

i wouldnt turn the crank they are already weak at close to 1000 hp we cracked ours in 4 spots
i would highly recommend main studs

 

[Extended Power]

It's rediculous...heavy ass steel crank, and they bend and crack....WTF???

For the $3100.00 the Stealership want for a new crank, you'd think they would stand up a lil better then they do...

 

[Cutting-Edge Diesel]

yeah that is crazy, glad i have a spare.

3100?! You can buy a complete engine for that much.

Probably getting paid at work to post this from my D1

I was going to buy an E-bay engine, and sell/trade the truck off.

Gotta draw a line in the sand at some point.

I really hope Matt's build will result in him finally getting the truck to run the way it was meant to run.

Ouch on the crank. From the pic, it doesn't seem like the scarring is too deep not to be polished. Could you see any stress fractures anywhere? I would think at 3k plus for a crank, you could get an aftermarket one, if someone made such a thing.

That would make mat happy. I bet
Iv seen a couple of cranks broke in half in service trucks.
why did cyl 4 rod bearing fail??

 

[Cutting-Edge Diesel]

why did cyl 4 rod bearing fail??

mystery so far

 

[Chvyrkr]

Hmm...

 

[Fast-6.0]

Probably the oiling system, thats the next weak link in the 6.0. Toss the crank. Why take the chance, its gonna take so much material off too clean up. Gotta agree with Ivan, how many times do you take this beating? I love the 6.0 but damn.......

 

[Cutting-Edge Diesel]

I have heard it both ways but looks like im using my other crank just to be safe.

 

[Dieselcraft]

Oil starvation is at 7n8 correct
Never seen or heard of oil starvation at cyl 4.
Could it been a operator error? Not torqued to spec?
Not tryin to start a fight just curious.
Here at the steelership as some say
We have a 6.7l 9k miles in cyl 2 rod bearing seized
It left us scratching are heads never seen it happen
But we've only worked on 2 for big repair cracked valves now seized rod bearing

Sorry for derail

 

[Extended Power]

After I spoke with Jim at Cunningham Rods about what happened with my engine, I wished I never took it apart until AFTER I talked with him...
I never thought to check the torque required to take the rod caps off to see if any of them had backed off, or stretched. I just took them apart...

Definitely will be documenting all measurements on bearing clearances, etc...

Way too expensive to take any "Short Cuts" on a rebuild.....so please take your time Matt...don't want to see any more "Failures" on your truck, or anyone else's.

 

[BFD99]

I'm just excited that hopefully Matt will be running it at Tulsa Raceway where I'll be able to see it alot!

 

[Dieselcraft]

I'll be ther watching to.
