How to replace a freewheel on a bike
Step 1
Grabbing the cogs is no good as you they spin on the bike freewheel without turning the central mechanism that is screwed on the hub shell. You need a special key to fit into notches or splines on the bike freewheel to turn it.
Step 2
Remove the rearwheel from the bike to gain access to the bike freewheel.
Step 3
Take out the quick-release skewer or remove the axle-nut on the drive side.
Step 4
Slide the freewheel-remover onto the axle and into the notches or splines on the bike freewheel.
Step 5
Replace the nut or the skewer to lock the key in place.
Step 6
Use a long adjustable spanner to turn the key anti-clockwise.
Step 7
Once the bike freewheel is moving remove the skewer or nut to allow it to unscrew all the way.
Step 8
If you have a bench vice you can clamp the key in it, drop the wheel gently onto the key then turn the wheel to unscrew the bike freewheel. Freewheel Suppliers in India
