Stripped Crank Arm

my crank arm is f555ed. i wiped and my pedal hit a 1/4 pipe at a wrong angle and it stripped the pedal right out the thread of the crank arm. the pedal's threads are still wicked cool but the crankarm is f555ed. any suggestions or must i but a new one? which is a good crankarm in your opinion?

The only thing that might work is a "tap and die" tool, wich is a hardened steel bolt that you thread through the bad thread and it cleans the threads up. But I have no idea if they even make a 9/16. Check your local hardware store to get a set of them for about 20 bucks or so.

Get a compatible kit on ebay, lots cheaper than replacing the crank arm...worth a try, anyhow.

Email empirebmx@empirebmx.com or ibeflip@aol.com (Albes). Explain to them what you want and where you live; they might be able to cut you a deal on shipping.

You're probably going to have to order via email, though, rather than the normal way.

They're not, they do, and so do I - 43 years worth. You have to do them right - granted, it's up for debate whether they'll work in this application, but I have several installed right now (on race car cylinder head stud holes) and they're fine and have been there for 4+ years.

The only potential issue with the tap and die solution is that the metal is weakened, and if you can retap to the original size, the resulting thread may be too weak to hold the pedal...especially if you're ramp riding like you mentioned. You can retap to a larger diameter, but you'll then need to find a shim to convert the pedal threads to a larger size. The ideal fix is a new crank arm or new cranks altogether (Oldschool Redline flights are my fave).
