Adjusting The Rear Derailleur - Schwinn S5477D Owner's Manual

4 Adjustments

ADJUSTING THE REAR DERAILLEUR

WARNING!
Ensure all bolts are secured tightly and the chain does not fall
off in either direction.
Although the rear derailleur is initially adjusted at the factory,
you will need to inspect and re-adjust it before riding the bicycle.
Adjust the Rear Derailleur
❶ Begin by shifting the rear shifter to largest number indicated
and place the chain on the smallest sprocket. Figure 4.16
❷ Adjust the high limit screw so the guide pulley and the
smallest sprocket are lined up vertically. Turn the high limit
screw clockwise to move the pulley away from the frame
Counter-clockwise to move the pulley towards the frame
Figure 4.17
❸ Shift through the gears, making sure each gear achieved is
done quietly and without hesitation. If necessary, use the
barrel adjuster to fine-tune each gear by turning it the
direction you want the chain to go. For example, turning
clockwise will loosen the cable tension and move the
chain away from the wheel, while turning counter-clockwise
will tighten cable tension and direct the chain towards
the wheel.

❹ Shift the rear shifter to gear one and place the chain on the
largest cog.
❺ Adjust the low limit screw in quarter turn increments until
the guide pulley and the largest cog are aligned vertically.
Turn the low limit screw clockwise to move the pulley closer
to the frame; counter-clockwise to move the pulley away
from the frame.
❻ Again, shift through each gear several times, checking that
each gear is achieved smoothly. It may take several attempts
before the rear derailleur and cable is adjusted properly.
