Do I need to re-peen?

[davesax36]

So I'm not sure about my peen job. I definitely mutilated the ends of the bills, but they're really not bent all the way onto the flywheel face. It doesn't seem to me that there's enough material to sort of fold them out there. Also, I used a punch with a point because my small pin punch snapped off while doing this.

They don't look bad at all, but you could also try this -
- leave the present peens alone. Pick another area of the flywheel/bolt thread, and try to make an indent on the flywheel, using a sharp centerpunch, or a small drill (1/8"). Then, again using the punch, push the corresponding bolt end metal into the indent.
An even more secure way is to have the bolt ends tack-welded to the flywheel. I think many owners have already gone this route.
Cheers!

They look good to me, as long as you used loctite you should be good to go. I never liked the idea of tack welding them, its a balanced part of the engine so I'd hate to go adding unknown amounts of weight to it but I know many have done it and been just fine, I'm just kinda anal about that kind of stuff...

I tried preening them once like they are from factory. No luck. I have mucho tools, punchs drifts etc. and couldn't find anything that looked like it was doing an effective job.
Plus the flywheel was on the crank at the time and I was pounding in it so hard I thought I might be damaging a bearing or thrust surface ( not that there are any in this motor! Haha)

I just made sure the threads and bolts were clean and grease free, cleaned with alcohol, and ran them in with non-removable (Theoretically) loctite.

I wouldn't have a problem with a small tack weld but did not see the need for it, and like Scott said if you want to be pedantic about it its adding unknown weight to a balanced assembly.

When it comes to that kind of stuff I'm very pedantic!! lol I just know when these things are balanced they are done to the gram, anything added is going to change things and that's not good at 9300rpm where I shift at I used Rusty's approach and I did peen them over some and mine looked pretty much like the OP's pics..

i always wondered what would hold better:

red loctite
jb weld
or some sort of epoxy,

and since people are tacking them anyways, seems like one of the other two options aren't all that bad.

I welded mine, but milled the beads down flush. It seems to be ok so far.

I really did consider putting jb weld on the threads instead of loctite. I did my best. It's going back together so I can see if it runs... Oh and it's gonna be a couple days because one of my garage door springs snapped this morning. Awesome.
