Binder Crank Replacement/Removal - Dynacraft SINGLE SPEED Owner's Manual

Binder (Boltless) Crank Replacement/Removal
Generally lubrication and maintenance repairs of this boltless
three piece crank set should be done by your local bike
shop. However, the crank arms require regular checking and
possible replacement.
1. Use a 6 mm Allen wrench to loosen or tighten the cap
screw in the binder end (2) and the end screw (1). The
binder end cap screw (2) needs to be very tight. If a torque
wrench is available tighten to 215 in/lbs.
2. Tap the crank lightly with a mallet to remove or replace the
crank. Note on the right side the crank arm is riveted to the
chainwheel and both will be removed or replaced together.
What is shown is the left side.
3. Repeat step one.
CAUTION
New binder (boltless) cranks may become loose with
initial use. Tighten the flange nuts (see illustration below)
after several hours of riding and repeat after use if
necessary.
