1 piece crank sprockets

[64lowrider]

How do you take a sprocket off a 1 piece crank?

 

[Rat Rod]

Normally you remove the entire crank assembly from the bike and then you are left with the crank and the sprocket. There is normally a large flat or cone shaped nut that holds the sprocket onto the crank. Remove that nut and the sprocket comes right off the crank.

Good call kev.. Theres a guy cross the road from me, The guy says, Oh ricky i bet if taken apart 10 times as many bikes as you! I helped him take out his crank assembley and fix the gyro on his sons bike.. :lol: That guy felt dumb.

Just to clarify... the backwards threads are on the nut and adjusting cone that hold the crank in the bottom bracket. The nut that holds the sprocket to the crank is normal thread (left to loosen).

Depending on the type of nut... if it has flat spots for a wrench use a large adjustable wrench or channel lock pliers. If it has the 2 slots I use screwdriver and a hammer. Helps to have a vise to hold the crank.

start charging people for your bike services, and you MIGHT be spared from working fast food when you turn 16.

I remember which side the left hand threads are by thinking "loosen" is always to the back of the bike at the top of your wrench rotation.

Or as you would sit to ride the bike - the left side is left hand (backward) thread.
