Anyone run into this?

Installing the flywheel today and found one bolt hole for the pressure plate is 3/8-16 not 5/16-18, evidently it was stripped and re-tapped larger. The issue now is a 9/16!socket won’t fit because the bolt head is too close to the flywheel & you cannot get any wrench on the head either. Anyone have any reason why I could use a button head socket cap screw in its place??? It will give a good baring surface, be easy to use an Allen socket to make sure it’s tight PLUS it’d be stronger material than the other 5 5/16 bolts in there now. The head will be low enough for any possible clearance issues.

Seems like a good solution. Instead of "won’t fit because the bolt head is too close to the flywheel", don't you mean too close to the pressure plate?

That'll work just fine.

There are various 3/8-16 header bolts with a smaller hex in 6 and 12 point hex.

The pressure plate sits down inside the flywheel so the bolt head clears the flywheel BUT is so close to it the socket will not fit between the head of the bolt and the flywheel.

I hadn’t thought about a 12pt head, I sell “industrial” fasteners and thought of a button socket cap as I sell them and have them in stock, 12pt heads “generally” are more “automotive” from my work perspective SO not as front and center in my mind as perhaps they should be.

Thanks!!

Hey rockfla,
Pictured here is a 1” and a 13/16”. Send me a Pm with your name and address and I will send both to you if one would work. 7/16 hex and 9/16 washer tang.

Thanks for the photos. I see the problem now. Either the button head or the header bolts will work fine.
