To adjust the freeplay 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.
