Maintenance; Wheel Bearings - BANWOOD CLASSIC Manual

Inspection of the Bearing

MAINTENANCE

Frequently check the bearings of the bicycle. Lubricate the bearings once a year or any time
they do not pass the following tests:
HEAD TUBE BEARINGS
The fork should turn freely and smoothly at all times. With the front wheel off the ground, you
should not be able to move the fork up, down, or side-to-sede in the head tube.
CRANK BEARINGS
The crank should turn freely and smoothly at all times and the front sprockets should not
be loose on the crank. You should not be able to move the pedal end of the crank from
side-to-side.

WHEEL BEARINGS

Lift each end of the bicycle off the ground and slowly spin the raised wheel by hand. The
bearings are correctly adjusted if:
• The wheel spins freely and easily.
• The weight of the spoke reflector, when you put it toward the front or rear of the bicycle,
causes the wheel to spin back and forth several times.
• There is no side-to-side movement at the wheel rim when you push it to the side with light
force.
Chain Adjustment
WARNING:
• The chain must remain on the sprockets.
If the chain comes off the sprockets, the
coaster brake will not operate.
• Do not attempt chain repairs. If the is
a problem with the chain, have bicycle
service shop make any repairs.
Adjustment:
The chain must be at the correct tightness. If too tight, the bicycle will be difficult to pedal. If
too loose, the chain can come off the sprockets.
When the chain C is at the correct tightness, you can rotate the crank freely and you can
pull it no more than one-half inch A away from a straightedge B as shown.
Adjust the tightness of the chain as follows:
• Loosen the axle nuts of the rear wheel.
• Move the rear wheel foward or backward as necessary.
NOTE: Make sure the rear wheel is in the center of the bicycle frame.
• Hold the wheel in this position and tighten securely.
Lubrication
WARNING:
• Do not over lubricate. If oil gets on the wheel rims or the brake shoes, it will reduce brake
perfomance and a longer distance to stop the bicycle will be necessary. Injury to the rider
or the others can occur.
• The chain can throw excess oil onto the wheel rim. Wipe excess oil off the chain.
• Keep all oil off the surfaces of the pedals where your feet rest.
• Using soap and hot water, wash all oil off the wheel rims, the brake shoes, the pedals, and
the tires.
• Rinse with clean water and dry completely before you ride.
• Using a light machine oil (20W), lubricate the bicycle according to the following table:
Lubrication Table (as equipped)
What When
Pedals every six months Put four drops of oil where the axles go into
the pedals.
Chain every six months Put one drop of oil on each roller of the chain.
Wipe all excess oil off the chain.
Derailleurs every six months Put one drop of oil on each pivot point of the
derailleurs.
Brake Levers every six months Put one drop of oil on the pivot point of each
brake lever.
Wheel Brakes every six months Put one drop of oil on the pivot point of each
cantilever brake.
Brakes and cable every six months Put four drops of oil into both ends of each ca-
ble. Allow oil to soak back along the cable wire.
Rear Sprocket every six months Lay the bicycle on its left side. Slowly turn the
Cluster rear wheel clockwise. Put four drops of oil in the
crack between the rear sprockets (which are
stationary) and the freewheel body (which is
turning clockwise).
Shock Fork every six months Lift up the rubber fork boot and dab a small
amount of grease on the fork leg just above the
plastic bushing.
