Lubrication
The chain should be lubricated with light oil at least every month, or more often in
wet, muddy, or dusty conditions. Be sure to wipe off excess oil, and not get oil on the
tires or rim braking surfaces.
Adjustment and Replacement
On derailleur geared bicycles, the rear derailleur automatically tensions the chain.
How to adjust the chain on single speed freewheel, coaster hub braked or 3 speed
hub geared bicycles:
1.
Loosen the rear axle nuts along with coaster brake arm clip and move the wheel
forward to loosen or backward to tighten in the frame.
2.
When correctly adjusted, the chain should have approximately 10mm
(3/8’’) of
vertical movement when checked in the centre between the chain wheel and
rear sprocket. Centre the wheel in the frame and retighten the axle nuts after
any adjustment. Bicycles which have a single speed freewheel, coaster brake or
3 speed hubs, generally use a wider type chain than derailleur geared bicycles.
These chains can be disconnected by way of a special U-shaped joining link that
can be pried off the master link with a screwdriver.
To replace, feed the chain around the chain wheel and rear sprocket and 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 chain wheel when
pedaling forward. 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 centred 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 chain wheel, rear
sprocket and derailleur cage with rivet facing away from the bicycle. Bring the
two ends together with the chain rivet tool and punch the rivet into place. Be
sure not to push rivet too far through the side plate.
