Which pedal has an opposite thread direction, for the purpose of removal?
The one-piece crank is a "Schwinn Approved" model from the early 1970's...

Thanks!

Easier to remenber-both pedals forward to tighten/rearward to remove. (the left clockwise to remove)

Traditionally, left, non-driveside. Both left and right thread in same rotation as the crank and wheels, backwards being removal.

Right pedal, right hand (normal, clockwise to tighten) thread; left pedal, left hand (reverse, clockwise to loosen) thread.

Do yourself a favor and get or borrow a proper pedal wrench for removal and grease the threads when reinstalling to ensure easy removal next time. I use Tef-Gel anti-seize and also fit stainless pedal washers to all of my pedals. They always pop right off.

Thanks a ton for the replies.
juls, I'm all about "easy to remember" methods!
