Missing Converter/Flexplate bolt

[SlickTR]

I just put in a PTC converter and I cannot get one of the bolts that bolt the conveter to the flexplate to line up right, I tried eveything I could think of. The other two went in just fine. I was using a lift at a hobby shop and they were closing so I buttoned everything up with two of the three bolts in so I could move the car. Is running it with only two bolts a bad idea? Anybody else have this happen to them?

It needs all 3 in it.

Did you have to drill any of the holes for the larger bolt? Sometimes they just need a little more clearance for everything to go together.

sounds like you tightened one or more of your bolts before you got them all started.loosen the two you have already in there and rotate the converter and then start the other bolt.

Yeah tried that didnt make a difference.

Dusty, I didnt have to drill any but that may have helped if I did. The other two fit fine and the third is really close just a tad off. Now if I can figure out how to work on that hole without dropping the Tranny again I'll be set, lol.

I've had to do it a couple times. A 90 degree or right angle drill as some call them will get the job done. Roll the flexplate around to the right spot and the drill can do the rest. I have also seen a 90 degree attachment that will work on a standard drill get into some tight areas as well.

My converter has 6 bolts and they have to be installed in a certain order. If I don't start the one I have marked first in the matching hole...they all won't fit.

I use a 90 degree angle grinder with a small carbide burr. It takes me about 5 seconds of grinding and im done. You should only need to alter one hole.

It's funny you mention this. My converter has 6 bolt holes, too, but I figured the other 3 were for some other application. However, it never occurred to me that if I turn it just right all 6 holes would line up. I guess I should/could be putting 6 bolts in it?

I had to do this for my PTC. Just a little grinding on one of the holes fixed me up.

I drilled out all 3 holes for the PTC...thought about doing only one but then thought it might throw the balance off...probably not...but by doing all 3 I know it's still balanced...

It's so close that very little will need to be taken away I think. I would imagine that it would not be enough to throw any thing off.

You don't need all six. Yours probably has both small and large bolt patterns. If your flexplate has both patterns then it won't hurt to put all six in but it's definately not needed.

The welded converters can get away with 3 bolt holes on even a 1500hp motor. The aluminum bolt togethers need to use all 6.

Thanks for that. I'm just going to use one set of holes. My flexplate has both patterns but I don't have 6 bolts.
