Remove A Shimano Hollowtech Crankset On A Bike
Step of 3: Replace A Shimano Hollowtech Crankset On A Bike
Modern bikes usually have cranks made of aluminium, they are mounted on an axle made of harder material, usually steel. If there's any play between the cranks and the crank axle the soft aluminium will soon get worn to the point where it's impossible to lock the cranks. If the cranks are loose don't ride the bike.
Undo Pre-load Cap
Undo and remove the plastic pre-load cap. It's only finger tight and is removed with a special plastic tool, designed specifically for Shimano Hollowtech cranksets.
Lift The Safety Tab
Use a small screw driver to lift the plastic safety tab.
Pull Off The Left-hand Crank
Wiggle the left-hand crank to loosen it and pull it off.
