Which Shimano pedals have reverse threaded bearing adjustments? I was attempting to tighten the bearings in my Shimano PD-M530 pedals. I've done this procedure several times before on my other pedals, and I've never had issues before (M737 and M980). For some reason, the drive side (right) pedal's bearing adjustment ended up being reverse threaded, and I stripped the threads on the locknut trying to remove it. The other pedals I've adjusted (see list above) all had regular threading on both the left and right pedals. Similarly, all the online guides describing SPD pedal service I’ve read or watched say that bearing adjustment is normal threaded.
What other models of pedals are reverse threaded on the bearing adjustment? I don't want to destroy a perfectly good (and expensive) set of pedals again.
I found the answer in this document: https://si.shimano.com/pdfs/dm/DM-PD0002-07-ENG.pdf#page27

NOTE:

Right-hand thread: Black-colored (without slit)
If the fitted lock nut is black-colored (without slit), the cone and the lock nut have a right-hand thread.
Left-hand thread: Black-colored (with slit)
Silver-colored If the fitted lock nut is silver-colored or black-colored (with slit), the cone and the lock nut have a left-hand thread.”


I pulled both pedals apart again, and lo and behold, the left pedal’s locknut is a brown color, while the right pedal’s is plain silver.
