removing pedals
 

on a 3 piece crank with 9/16" threads which way do you turn the pedal shafts to remove them? i don't remember the proper way.

Are you talking about crank arms or pedals? I'm super confused...

Pedals you turn towards the rear - so righty loosey for the NDS and lefty loosey for the DS.

Did you miss the thread title?

No, but I also read the OP.

"also" - so you did or didn't miss it?

The only threaded part of the crank is where the pedals are installed...the 9/16" should have also given that away.

You going to add some content then or you just here to troll me?

You're making it easy. Also - clarified your confusion for later readers.

The right side is right (-handed threads, so righty-tighty, lefty-loosey when facing the right side of the bike).

The left side is not (it's left-handed threads, so righty-loosey, lefty-tighty when facing the left side of the bike).

When the bike is upright, and a pedal wrench is upright, then for BOTH pedals, turning the wrench towards the front of the bike is tightening (to get the bike ready to ride (forward) you should tighten your pedals), and turning the wrench towards the rear of the bike is loosening)

If you think about it, these mnemonics agree with each other.

Your snark isn't very good. It's too overpowering to be entertaining and not subtle enough to show proper refinement. You're not going to make it here on BF.

The side with the chain rings is righty tighty, lefty loosey. The opposite side, is the opposite (lefty tighty, righty loosey)

LH thread Pedal Is Marked

"Making it" on bf means something to you? Don't quit your day job.

Btw a snark is an imaginary animal; brush up on some English there bud.

edit - looks like I need to brush up some English instead.

I simply meant you will likely become a banned user in the near future not that you would somehow strike it rich in the world of bikeforums.net.

Snark has more than one meaning.

Origin
mid 19th century: originally in the dialect senses ‘snore, snort,’ ‘find fault.’

Well I'll be, looks like you out English'd me, point to you right there (herein my vested interest in most conversations is revealed, hence my peanut gallery commentary laced with cheap tricks which work almost every time).

And may the gods of bf have mercy on me lest I be banned and retreat back to real life!!

Since OP got his question answered, I recommend a mod close this thread down before 1983 and RPK79 escalate to a point where they both get banned!

Don't worry about me. I'm over it. Your correct though; OP has had their answer since post 2 and several times since.

With the bike upright, Turn your wrench over the top toward the back of the bike to remove and toward the front to tighten. This is true whether using the flats or an allen wrench from the back.

I've never liked the "righty-tighty" concept for pedals. It's OK if you use a pedal wrench, but if the pedals use a hex from the back it can get confusing, in particular if you have to remove the crank to get enough leverage and remove the pedal with the crank in a vice.

If you assemble enough bikes you soon get used to tightening pedals by freewheeling, so it's easy to remember removal is just the opposite...

This is true, but before you can freewheel the pedals on or drive the pedals off, you have to remember the threading rule in order to either initially thread them or crack them loose. Besides, as a mnemonic it's backwards (to me) -- it would be easier to remember if you drive the wheel in order to drive the bike (when you need the pedals on), and freewheel if you don't want to drive the bike (when you want the pedals off), but unfortunately that's opposite of the way the mechanisms actually work.

You're right, the righty-tighty/lefty-tighty mnemonic suffers from its dependency on perspective.

However, the wrench forwards/on vs backwards/off suffers from a dependence on an upright bike. Half the time I take pedals off I turn the bike upside down, which reverses that mnemonic (and makes it not memorable). For people with easy,convenient access to workstands all the time (i.e. shop mechanics), this is not an issue.

Not really.

To install, put the pedal in place by hand and freewheel until the treads engage, then finish up with the wrench.

To remove, put the wrench on and go opposite of freewheel to break free.

After you've built a few hundred bikes this becomes automatic...

I'd be afraid of cross-threading. I ruined a nice crank once by letting a friend's kid 'help' me with some pedals, I didn't realize he had cross-threaded my pedal and jammed it in there until the pedal fell out when I was riding. Fortunately a local shop was able to save the crank with helicoil.

I refer you to my "After you've built a few hundred bikes" remark... :beer:
