Stripped Pedal Threads

No, it wasn't secondhand, I got it from bikesdirect.  They say no warranty, which doesn't surprise me too much because I saw that FSA specifically excludes stripped threads from their warranty.

I'm hoping to just be able to replace the driveside arm, since the rest of the crankset is fine.  They're going to quote me a price on the part, but I figure I'll compare that with LBS prices.

Can anyone comment on how hard it would be to replace that part?  I'm reasonably mechanically inclined, imagine I would have to buy a couple of tools, but I think I'd just as soon spend money on tools rather than bike shop labor if it's something I can do myself.

It is Mega Exo, and I noticed that the bolts were Torx.

Bikeisland.com (affiliated with BD) sells the whole Energy compact crankset with bottom bracket for $164, so hopefully they'll do me a deal on just the crankarm.

New twist on this question--do I need to get exactly the same brand & model of crankarm, or will any 5-arm, 110mm BCD, 172.5mm crankarm work? 

Are they reasonably interchangeable, or is there something unique about the crankarm/chainring interface?

Well, as it turns out, it's impossible to buy just a crankarm, only a whole crank, and FSA specifically excludes pedal threads from their warranty.  To their credit, Bikesdirect did offer to sell me a new crank a their cost.

But thanks to BT Classified and especially cooutdoors, I got a good deal on a lightly used standard crank.  Went on like a charm and rides fine.

If anybody needs some spare compact chainrings, check Classifieds.

Thanks to everybody for all the tips.

I don't know if a helicoil would work in the crank arm because it's so thin but the difference in price would certainly make it worth looking into. You would be able to install it without taking the crank arm off.

There is also another solution that is very similar to the helicoil that is suppose to be a little better and is a lot more expensive. I can't recall what the name of that system is, if you think you want to consider either of those options let me know and I'll call the hardware store to get the specific name.

If you go to Lowes or Home Depot and ask for a helicoil,you'll probably get a glazed stare and they'll say what?

A question you should ponder though is what caused the threads to go bad, did the pedal keep coming loose?

You'd think you could buy that part separately, but it turns out not.  I checked with a couple of bike shops and they couldn't even special order it--you have to buy the whole crank.  Best you can do is get it without a bottom bracket, which only saves about $10-20.
