Hello! I have an extra non-drive side Bullseye crank arm that has either been re-threaded incorrectly or possibly a factory faux pas. The issue is that the non-drive side crank arm is designed to slope away from the chain stay when installed in the correct orientation. However, the pedal lug's threads on this arm are tapped to accept the pedal from the wrong side, which if installed in that manner, will not clear the stay. I hope this makes sense. Essentially, the threads are backwards.
I surmise the following:
1) someone installed backwards, forced the pedal, rethreading it unintentionally with force
2) someone rethreaded intentionally but had the wrong orientation
3) factory blunder
Either way, I want to correct it and am seeking input on whether this can be easily accomplished. The threads are clean and allow for easy pedal installation but from the wrong side, so I'm leaning towards scenario 2 or 3 being the case. I've rethreaded aluminum cranks which is no problem but the hardness of the Bullseye steel gives me pause. My taps are hardened steel and of high quality (Park), but again, I've only used them on aluminum cranks. Thoughts or insights would be greatly appreciated before I attempt it.
Cheers!
