Freewheel sprocket

When replacing the freewheel sprocket remove frame 
covers  if  necessary.  Remove  the  chain  according  to 
section ”Chain 1/2” x 1/8””. 

Loosen the axle nuts and lift off the flywheel. Remove 
the  axle  nut,  washer,  chain  adjuster  and  spacer  on 
the  freewheel  side.  Replace  sprocket-adaptor  and 
assemble the new parts in reverse order according to 
the above.

The sprocket should be lubricated with a few drops of 
oil once a year. Tilt the cycle to make it easier for the 
oil to reach the bearing. See
