E4OD Flexplate Failures

[brdmh44]

Hi guy's, I was curious if anyone else is having failures with the stock (Ford) flexplates?

I have had to replace 3 flexplates in 3 different trucks this year (IDI/E4OD) and when I went to start my truck today, the infamous noise appeared and I limped it back to my shop

Thank god I just put that trans in a month ago so I know the bolts and exhaust will drop easy

I am really curious if I am the only one who has this constant problem.

Also, is there anyone here running an aftermarket upgraded flexplate? Do they even exist?

I had a heavy heavy flexplate in my 91 7.3/e4od. solid cast iron and it never gave me a problem even though the trans did.

Those heavy cst iron flexplates and the thin stamped flex plate part of them are no longer available. I bought the last thin plate Ford had in inventory 4 years ago... I did a nationwide search for it. I found one on ebay and bought that kit too... nobody else bid on it so.... Give BTS in leadhill arkansas a calll. They have a nice flex plate that comes with their E4OD trans. The triple disc converter they use is so large you need their flexplate... I was running the heavy cast iron plate. I did try to test fit the converter just to se if they were selling me "something".... Yeap... They were telling me the truth. Are you finding your bellhousing alingment dowls in place when you remove the trans. Also what about that crank spacer. What kind of condition is it in. This time when you remove it use some 300 grit wet and dry paper and a piece of glass or mirror to sand flat any burrs or rust on it. Maybe a flat smooth fileon the plate side will clean up and inperfections. Sounds like you have something out of alingment at the crank....

I forgot- are the 6.9 heavy cast flex plates compatable?

 

[icanfixall]

Bill... Any heavy cast iron flexplate will function fine of any 6.9 or 7.3 engine but they will not fit with a triple disc converter. those require a single flexplate setup.

Got ya Gary - What I was thinking is the C6 & E40D the same pattern? Darn there I go tryin to think again!

There are multi disk converters available, that will fit the old flex plate/ flywheel.

BTS uses a PI converter with a larger diameter. So he requires the later tin flex plate.

Thats the setup BTS sold me to fit the triple disc converter they use... the stock converter has 25 square inches of friction material and the BTS triple disc converter has 150 square inches of friction material... I can't wear it out with my tiny little idi horse power...

You will break the engine before the converter or tranny fails.
