Technical Service Instructions
SI-F917A
Front Drive System
Before use, read these instructions carefully, and follow them for correct use.
General Safety Information
WARNING
• Use neutral detergent to clean the chain. Do not use alkali-based or acid based detergent
such as rust cleaners as it may result in damage and/or failure of the chain.
• Use the reinforced connecting pin only for connecting the narrow type of chain.
• There are two different types of reinforced connecting pin available. Be sure to check the
table below before selecting which pin to use. If connecting pins other than reinforced
connecting pins are used, or if a reinforced connecting pin or tool which is not suitable for
the type of chain is used, sufficient connection force may not be obtained, which could
cause the chain to break or fall off.

• If it is necessary to adjust the length of the chain due to a change in the number of
sprocket teeth, make the cut at some other place than the place where the chain has been
joined using a reinforced connecting pin or an end pin. The chain will be damaged if it is cut
at a place where it has been joined with a reinforced connecting pin or an end pin.

• Obtain, read and carefully service instructions when installing parts. A loose, worn, or
damaged parts may cause injury to the rider.
We strongly recommend that only genuine Shimano replacement parts be used.
• Keep these Technical Service Instructions in a safe place.
Note
• Apply grease to the bottom bracket before installing it.
• For smooth operation, use the specified outer casing and the bottom bracket cable guide.
• This front derailleur is for triple front chainwheel use only. It cannot be used with the
double front chainwheel, as the shifting points do not match.
Outer casing holders
• When installing the top route type, choose a frame that has three
outer casing holders as shown in the illustration at right.
• Use an outer casing which still has some length to spare even when
the handlebars are turned all the way to both sides. Furthermore,
check that the shifting lever does not touch the bicycle frame when
the handlebars are turned all the way.
• Grease the inner cable and the inside of the outer casing before use
to ensure that they slide properly.
• The SC-C050 speedmeter, SC-C051 odometer and SC-C052 clock and stopwatch are
available as separate items. Please ask your bicycle dealer for further details.
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For maximum performance we highly recommend Shimano lubricants and maintenance
products
• For any questions regarding methods of installation, adjustment, maintenance or operation,
please contact a professional bicycle dealer.

For chains, insert the chain gauge (TL-CN24)
into the inner link which is next to the chain
connecting pin to check that the inner link
width is correct.
Check that the connecting pin pro-trudes
past the outer link by the same
amount on both sides, and that

the amount of protrusion is
0.2 mm or more.

Inserting the inner cable
Insert the inner cable into the outer casing from the end with the
marking on it. Apply grease from the end with the marking in
order to maintain cable operating efficiency.

Cutting the outer casing
When cutting the outer casing, cut the opposite end to the end
with the marking. After cutting the outer
casing, make the end round so that the
inside of the hole has a uniform diameter.
Attach the same outer
end cap to the cut end
of the outer casing.

Cut off the excess length of inner cable
and then install the inner end cap.

5. Troubleshooting chart
After completion of steps 1 - 4, move the shifting lever to check the
shifting. (This also applies if shifting becomes difficult during use.)
If the chain falls to the crank side.
Tighten the top adjustment screw
clockwise (about 1/4 turn).
If shifting is difficult from the
intermediate chainring to the
largest chainring.
Loosen the top adjustment screw
counterclockwise
(about 1/8 turn).
If shifting is difficult from the
intermediate chainring to the
smallest chainring.
Loosen the low adjustment screw
counterclockwise
(about 1/4 turn).
If there is interference between
the chain and the front derailleur
inner plate at the largest
chainring.
Tighten the top adjustment screw
clockwise (about 1/8 turn).
If there is interference between
the chain and the front derailleur
outer plate at the largest
chainring.
Loosen the top adjustment screw
counterclockwise
(about 1/8 turn).
If the intermediate chainring is
skipped when shifting from the
largest chainring.
Loosen the outer casing
adjustment barrel
counterclockwise (1 or 2 turns).
If there is interference between
the chain and front derailleur inner
plate when the rear sprocket is
shifted to the largest sprocket
when the chainwheel is at the
intermediate chainring position.
Tighten the outer casing
adjustment barrel clockwise
(1 or 2 turns).
If the chain falls to the bottom
bracket side.
Tighten the low adjustment screw
clockwise (about 1/2 turn).
Installation of the switch
