Lubrication
The chain should be lubricated with light oil at least every month, or after use in wet, muddy, or dusty conditions. Take care to wipe off
excess oil, and not to get oil on the tires or rim braking surfaces.
Adjustment and Replacement
On derailleur geared bicycle the rear derailleur automatically tensions the chain.
To adjust the chain on single speed freewheel, coaster hub braked or 3-speed hub geared bicycles:
1. Loosen the rear axle nuts (and coaster brake arm clip if fitted) and move the wheel forward to loosen, or backward to tighten, in the
frame.
2. When correctly adjusted, the chain should have approximately 10mm of vertical movement when checked in the center between the
chainwheel and rear sprocket. Center the wheel in the frame and re-tighten the axle nuts after any adjustment. Bicycle that have a
single speed freewheel, coaster hub brake or 3-speed hub, generally use a wider type chain than derailleur-geared bicycles. These
chains can be disconnected by way of a special U-shape joining link that can be pried off of the master link with a screwdriver.

To replace, feed the chain around the chainwheel and rear sprocket, fit the master link into the rollers into each end of the chain,
position the master link side plate, and slip on the U-shaped snap-on plate. Make sure the open end of the U-shaped plate is trailing
as the link approaches the chainwheel when pedaling forward.

Chain

Inspection
The chain must be kept clean, rust fee and frequently lubricated in
order to extend its life as long as possible. It will require replacement if
the stretches, breaks, or causes inefficient gear shifting. Make sure that
there are no stiff links, the must all move freely.
Detailed Maintenance
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 form the rivet. To install, feed chain around chainwheel, rear
from the rivet. To install, feed chain around chainwheel, rear sprocket and
derailleur age with rivet facing away from the bicycle. Bring the two ends
together within the special tool and punch the rivets into place. Be sure not
to push rivet too far through side plate.

FREEWHEEL

Chain Rivet Tool
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.
