Derailleur geared bicycles use narrower chains and require a
special tool to fit and remove chain links, or to change the length.
To remove, fit the rivet tool so that the punch pin is centered over
any one of the chain rivets. Push the rivet almost all the way out,
then back out the punch and remove the tool. Holding the chain
on both sides of the punched rivet, bend it slightly to release link
from the rivet. To install, feed chain around chainwheel, rear
sprocket and derailleur cage with rivet facing away from the bicycle.
Bring the two ends together within the special tool and punch the
rivet into place. Be sure not to push rivet too far through side plate.
FREEWHEEL
Inspection
Like the chain, the freewheel must be kept clean and well
lubricated. If the chain has become worn and needs replacing,
then it is likely that the freewheel will also have become worn and
should also be replaced. Take the chain off the freewheel and
rotate it with your hand. If you hear a grinding noise or the
freewheel stops suddenly after spinning it, it may need adjustment
or replacement. Such action is beyond the scope of this manual
and you should consult a specialist.
