Three-Piece Cranks (various models)
Maintenance:
Both Crank Arms
A
were tightened to the spindle
B
at the factory. After
riding the bicycle the fi rst few times, make sure the crank arms have not loosened. If either
crank arm has loosened during this “break-
in” period, re-tighten or have it tightened
by a bicycle service shop.
Frequently check the tightness of the
crank arms. If loose, tighten or have them
tightened by a bicycle service shop.
WARNING
:
If you ride the
bicycle with a loose crank arm, the crank
arm may fall off . The spindle may also
damage the crank arm.
Inspection of the Bearings
Maintenance:
Frequently check the bearings of the bicycle. Have a bicycle service shop lubricate the
bearings once a year or any time they do not pass the following tests:
Headset 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-side 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 refl ector, 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.
