Lubrication and Adjustment - One Piece Cranks

To adjust the free play in a one piece type bottom bracket, loosen the locknut on the left side by turning it clockwise
and tighten the adjusting cone counter-clockwise using a screwdriver in the slot. When correctly adjusted, re-tighten
the locknut counter-clockwise.
To disassemble:
1. Remove the chain from the chainwheel.
2. Remove the left pedal by turning the spindle clockwise.
3. Remove the left side locknut by turning it clockwise and remove the keyed lockwasher.
4. Remove the adjusting cone by turning it clockwise with a screwdriver.
5. Remove the left ball retainer, slide the crank assembly out of the frame to the right, and remove the right ball retainer.

Clean and inspect all bearing surfaces and ball retainers, and replace any damaged parts. Pack the ball bearing
retainers with grease, then re-assemble in the reverse of the above procedure.
