Broken Flywheel 1999 F-350 Dually Crew Cab 7.3L

[Formula Racer]

I have had 2 different dealerships and one transmission shop install 5 flywheels with the adapter plate, per the Ford TSB, in the last 50K miles and it has now failed again. Thankfully under the 12 month / 12K mile warranty. None of them seem to be able to solve the real problem except for throwing parts at it. Does anyone know the cause?

you have a line up issue , or to much crankshaft end play, hard to say really without looking at something like that

Thanks for the rely. The truck is stock! Definitely needs an expert to look at it and I doubt that would be a Ford mechanic

stock or completly built makes no difference in flywheel durability , i am/was a ford mechanic and there are alot of good ones out there , ford paid my bills for 21 years until a month ago, so just because you havent had luck with the one you dealt with , dont bash the rest

Accept my apologies, I just happened to run into 2 at 2 different dealerships that cannot think outside the box. I am trying a different dealership next.

What type of flywheel are they putting in? If its a dual mass like stock then that could be a start.

It goes from a slight chatter to a loud rattle within 20 - 30 miles and the entire center is broken loose when they remove it. I've seen a few other posts with the same situation.

Interestingly when first purchased it was replaced at 10K and again at 14K, this time using the Ford TSB 99-23-6. That lasted until 102K. Then replaced at 124K, 129L, 142K and 147K. I now have 157K and it is broken "again".

So I am told keep the 7.3L, so far the best Ford diesel. The truck is immaculate. But this is getting old and I don't even tow regularily any more since I quit formula racing in 2006, except for an ocassional trip to the lake with a 20' boat on an aluminum trailer.

I'm a Ford truck guy and refuse to try Mopar again and won't go GM.

Heh Ford Buddy, I am now told that Ford engineers think a new tranny is the solution. What do you think. Probably going to be a $3K price tag +/-.
