Well, I picked up another block the other day from a junkyard
and went to tear it down today. F22b2 motor.

Sure enough, this crank bolt is messed up too.

I got the bolt out but half of the threads are stripped on it.

It looks like I'm going to have to rethread the crank to save it.

My question is what bolt can I use after I rethread it?

The original bolt is most likely going to be too small.

I'm curious if any of you have done this procedure and which bolt you
ended up using for the newly threaded crank.

TIA

 

I'm thinking I can drill it out a little bigger and possibily use a helicoil
that will match the original crank bolt size.

hmmm....................

When you got the bolt out, did you drill it out or use an easy out or something? If there's still bolt left in there...you could just rethread it for the same size.

Otherwise, find someone with automotive grade bolts (I forgot what they were called) and find one which is a tad bigger than the stock crank bolt. Thread it for that one.

IIRC, that will get expensive with the bigger threads, but it's the best way to do it.

I believe I have also heard someone say there's a suspension bolt that will fit on the crank pulley, but don't take my word for it.

Someone tried that on the last f22 block I picked up, wasn't a good idea.

So what's expensive about it, the tool to thread it bigger?

So YOU'RE the unlucky bastard I read that from!!! Haha, whoops!

IIRC, the little kit is expensive...the tapping tool and the coils.

 

chris were the threads on the bolt stripped or in the crank or both.. you might be able to get away with just runing the right size tap back thru the orginal crank bolt hole to clean the threads up, or put plenty of oil on the crank both and thread the sucker in.. i guess it comes down to what do you consider the right way to do it , and how much work do you want to put into this car
