Loose crank


It sounds like it is probably a "cotterless" crank, which is now fairly common on modern-day mid to higher level bicycle. These cranks are mounted on the tapered ends of a hardened steel axle. The cranks are aluminium alloy and are easily damaged so they need to be protected when you are tightening them. To properly tighten a cotterless crank, remove the covers that are threaded into the crank over the bolts securing the crank to the axle. Place one crank against a solid point of support (centered on the axle) but protected from damage with a block of wood. Use another block of wood (centered on the axle) with moderately heavy (2 lbs or so) hammer. Strike block of wood as close as you can to the centerline of the axle several times with a heavy blow (like you would need to drive a 16d framing nail). Then tighten the bolts that secure the cranks to the axle and replace the dust covers. Provided the crank didn't become so loose that the tapered sockets on the cranks became mis-shapened, this should solve your problem.

I need to take my bicycle crank apart


I assume you have a three piece crank (axle plus two crank arms). Go look at the Park Tools website. You will need to remove the little hubcap about the size of a 50 cent piece, then remove the nut on the end of the axle, then use a crank puller to pull the crank off. The crank puller is like a wheel puller in that it has a bold in the middle the pushes against the end of the axle, but instead of having jaws the hook on the outside of the wheel, it has a large male thread that screws into the threads where the hubcap was screwed into. Good luck.

Hello there. Unfortunatley there is no way other than removing the crank arms. You do need to remove the nut on the axle and you will need a crank puller. The puller is available at any local bicycle shop for around 10-15 dollars.

How to disassemble crank bearing on Schwinn Mesa Mountain Bike


You wil need a couple of special tools, or be fairly creative with the tools you have.
  1. remove the dustcovers in the crank arms at the crank axle
  2. loosen the crank retaining nut/bolt.
  3. thread in a chank puller and pull the crank arms.
  4. remove the lock ring on the adjustable side of the crank axle (Requires lock ring wrench)
  5. remove adjustable bearing cup.
  6. remove axle and bearings
  7. replace or repair as needed.
Once you have it opened up ou can determine if you need new bearings or crank axle.
to assemble, reverse above procedure, insuring bearing play is minimalized.

Hope this helps.
