I got a 24mm 3/8 drive socket , and ground the edge down till it was square across the end. to take my pedal off. (crankset swap)
FWIW the Light weight Kit includes a Ti plug for the core of the folding pedal,
It comes off with an Allen wrench fitting in a socket in the left pedal core..
IMHO.. TA pedal washers are a good thing I want them on all my cranksets ..
