How do I take cranks off?

I think my cranks are too loose on my giraffe. I took the end nuts off the
cranks to take them off and tighten them, but I can’t get the cranks off.
Do I need to hit them with hammer and board?

Oh God no! DONT HIT THEM WITH A HAMMER! Go to your local bike shop and buy a crank arm remover they should only run you about $8 or so, And its a very useful tool to have around. This is assuming that you have cotterless cranks. If your cranks are cottered, then just loosen the pin.

ya! you need a crank puller

but if your cranks were loose,they sould have come off when you took off the nuts.(yikes)

It sounds like you have three piece cranks on your giraffe. You’ll need a crank puller to remove them.

See


for some info on removing and installing cranks.
The crank puller I use is made by Park Tool

Not all giraffes use three piece cranks. My Schwinn giraffe uses a one piece crank, which is a totally different beast. One piece cranks are all one unit shaped a bit like a letter “z”.

If you’re still unsure about how best to retighten the cranks just take your giraffe to a bike shop and they can fix it.

Hey there, You can get a crank puller, unless you own/have access to a
steering wheel puller for a car, that works fine too. Dustin Zupancic
