This seems weird. Someone didn't install a set screw through the balance did they?

 

Interesting, two broken ARP's referenced in this thread, yet I've never heard of a broken stocker...

 

In the case I was referring to, it wasn’t the ARP bolt's fault. They make fine products, but even though the assembler recognized the fact the bolt was longer than the stock piece, he didn’t think it would cause an issue. He was unfortunately mistaken.

 

I called ARP today. They were pretty surprised and asked if I could send the broken bolt to them to check out. Unfortunately they didn't have any suggestions for extracting the rest of the bolt. Right now its looking like I'm going to have to pull the crank and have a machine shop remove it.

 

Yep, quite a few people have overloaded and shredded threads trying to re-install the damper using the crank bolt rather than an install tool. Then when you try to remove the bolt SNAP.

 

Man, I thought I was screwed when I snapped the bolt off the crank puller.

My stomach would be up in my throat in your situation.

 

I didn't count yours since you mentioned the bolt was too long...that would be 3 broken in this thread

 

i dont know but ive pulled mine twice now and used the arp bolt no issues.

 

My installation tool has always been a propane torch... It really doesn't have to get that hot even. I have put on a stock one on this way several times and an underdriven one as well. Never any damaged threads as the balancer just slides right on by hand...

 

thats wierd. how the heck can you f' up a m16 x2.0 pitch thread?

you have to push the bolt in there like a inch before you can start the thread, so the bolt cant really wobble around to get it cross threaded.. my guess is someone got a little "impact happy"
