Vado Crank Removal

[Quadracer]

Hi All, Can someone tell me the process of removing the Vado Cranks. The inner hex turns half a turn before it stops - I didnt want to force it.

By your description it sounds like it may have a self-extracting arm; when you loosen the bolt it pushes against the outer cap which drives the arm off. Such a system does require force to remove the arm.

If you post a photo I could tell you for certain.

Thanks Nova for your help, the crank has an inner and outer hex.

That is a self-extracting arm. The outer hex is the cap which is threaded into the arm. When you loosen the inner hex, it pushes against the cap to drive the arm off. You're breaking the bond between the steel crank spindle and the aluminum arm (which is in essence stretched over the spindle) so it does require an initial high amount of torque, after which is becomes easier to turn once the bond is broken.

Just curious, what is the reason why you need to remove the crank arms?

Thanks so much Nova, I hate not knowing how it works. I have creak in the drive chain somewhere, Im going to change pedals soon so if that wont solve it will check the cranks and re-grease. Thanks again.

Can someone verify if this is correct? My right side pedal will not unthread so I want to remove the crank arm to get a better handle on things.

You do know the pedals are left and right hand threads?

Verified above. The inside allen plug is the extractor. Helps to have a long bar for removal, she don't give it up easily.

Left side is lefty. Right is Righty. I think what threw me, I knew the left side was left hand thread, so I was prepared when I installed the allen key for removal and set the ratchet for right hand thread. On the right side, I forgot my strategy and set the ratchet for right handed thread which should be left hand for removal with the allen key.

It's all in the strategy.

A good way to get this right every time is to stand at the rear of the bike and pull the pedal wrench to you to remove either pedal.
