My 95 f350 4x4 dump keeps breaking flexplates and I cant figure out why. crank doesn't seem to walk, replaced the driveshaft... trans had been broken by some plow cowboy... any thoughts? and does anyone have a another one or at least a case I can use?

 

Where is it breaking them at ?

 

Right around the crank bolts in a perfect circle

 

Is the flexplate spacer in there ?

 

Which one?

 

I think this is the one Mike is talking about.

Yes I have that. It needs replaced because the edhe is ground down from the plate breaking. Doesnt seem to have crank walk either

 

There is a thin plate (1/8"?) that goes on the other side of the flexplate than the beefy one shown.
If that's missing I'd guess the bolts are putting too much stress on the plate.

 

Matt, if it helps I am in NE Ohio and have a flexplate, the thin spacer Jim is talking about and a full set of bolts. I'll make you a sweetheart of a deal on them. Shoot me a PM if that will help you in any way.

 

Dont the bolts go through it as a washer or is there supposed to be a thin plate on each side of the flexplate?

 

The small ring that goes on the "outside of the flexplate, IIRC, the bolts do go through it. It's essentially a big washer that all the bolts go through, then the flexplate, then the big chunky spacer, then into the crank.

 

I can post a pic after I get home if it helps.

 

Yes the small one is what I was thinking of.

 

Ok I have all that.
