• Use the reinforced connecting pin only for connecting

the narrow type of chain.
• There are two different types of reinforced connecting pins 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
End Pin
Link Pin
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.
• Check that the tension of the chain is correct and that the chain is not damaged. If the tension is too weak or the chain is
damaged, the chain should be replaced. If this is not done, the chain may break and cause serious injury.
• Use a front chainwheel which is compatible with 9-speed chains in conjunction with Shimano CN-7701,
CN-HG93 and CN-HG73 chains. If a chainwheel for an 8-speed chain or less is used, front chainwheel gear shifting problems
may occur, or the chain pins might fall out, causing the chain to break.
• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn, or damaged parts may cause injury
to the rider. We strongly recommend only using genuine Shimano replacement parts.
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.
Note
• If gear shifting operations do not feel smooth, wash the derailleur and lubricate all moving parts.
• If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur.
• You should periodically clean the derailleur and lubricate all moving parts (mechanism and pulleys).
• If gear shifting adjustment cannot be carried out, check the degree of parallelism at the rear end of the bicycle. Also check if the
cable is lubricated and if the outer casing is too long or too short.
• If you hear abnormal noise as a result of looseness in a pulley, you should replace the pulley.
• If the wheel becomes stiff and difficult to turn, you should lubricate it with grease.
• Do not apply any lubricant to the inside of the hub, otherwise the grease will come out.
• You should periodically wash the sprockets in a neutral detergent and then lubricate them again. In addition, cleaning the chain
with neutral detergent and lubricating it can be a effective way of extending the useful life of the sprockets and the chain.
• If the chain keeps coming off the sprockets during use, replace the sprockets and the chain.
• Adjust the RD-M760 reverse spring type rear derailleur from the low side.
• Use a frame with internal cable routing is strongly discouraged as it has tendencies to impair the SIS shifting function due to its
high cable resistance.
• Always be sure to use the sprocket set bearing the same group marks. Never use in combination with a
Group marks
sprocket bearing a different group mark.
• 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.
• Make sure that the gear shifting cable and the brake cable do not obstruct each other during braking
operations. If they do obstruct, it may interfere with braking.
Install the cables so that they still have some slack in them even when the handlebars are turned fully in
either direction.
• A special grease is used for the gear shifting cable (SIS-SP41). Do not use DURA-ACE grease or other types of grease,
otherwise they may cause deterioration in gear shifting performance.
• Grease the inner cable and the inside of the outer casing before use to ensure that they slide properly.
• For smooth operation, use the specified outer casing and the bottom bracket cable guide.
• Operation of the levers related to gear shifting should be made only when the front chainwheel is turning.
• If the brake fluid used in the oil disc brakes is of a type which tends to adhere to the plastic parts of the shifting lever, this may
cause the plastic parts to crack or become discolored. Therefore, you should make sure that the brake fluid does not adhere to
these plastic parts.
The mineral oil which is used in SHIMANO disc brakes does not cause cracking or discoloration if it adheres to plastic parts, but
such parts should be cleaned with alcohol beforehand to prevent foreign particles from adhering.
• Do not disassemble the indicator and shifting lever unit, as this may damage them or cause mis-operation.
• 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.

These Service Instructions describe the operation method when using the SL-M751 shifting lever in combination with the RD-M760
reverse spring-type rear derailleur. If using in combination with a top normal-type derailleur, the operations and indicator displays will
be reversed.
Gear shifting operation
The lever always returns to the initial position when it is released after shifting. When operating the lever, always be sure to turn the crank
arm at the same time.
To shift from a large sprocket to a smaller sprocket
To shift from a small sprocket to a larger sprocket
To shift one step only, press lever to the (1) position. To shift two
steps at one time, press to the (2) position.
Press lever once to shift one step from a smaller to a larger
sprocket.

Installation of the rear derailleur
When installing, be careful not to let the B-tension adjustment screw
come into contact with the dropout tab, otherwise deformation may result.
Do not remove the Pro-Set alignment block at this time.

Chain length on bicycles
with rear suspension
The length of A will vary depending on the movement of the rear
suspension. Because of this, an excessive load may be placed on
the drive system if the chain length is too short. Set the length of
the chain by adding two links to the chain when the rear suspension
is at a position where dimension "A" is longest and the chain is on
the largest sprocket and the largest chainring. If the amount of
movement of the rear suspension is large, the slack in the chain
may not be taken up properly when the chain is on the smallest
chainring and smallest sprocket.

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.
The sealed cap with tongue
and the rubber shield should
be installed to the outer
casing stopper of the frame.

* If the rear derailleur moves to a large degree, such as in
bicycles with rear suspension, it is recommended that you
replace the cap with the

accessory aluminum cap.
The end of the outer casing
which has the aluminum cap
should be at the derailleur side.

the largest sprocket. Then operate lever once to move the
derailleur to the 2nd-gear sprocket. After this, operate lever just
as far as the extent of play, and then turn the crank arm.

the chain touches a sprocket and
generates noise.
* Turn the adjustment bolt together with
the outer casing adjustment barrel
cover.
Best setting
The best setting is when the cable adjustment bolt is tightened
(turned clockwise) until noise occurs without lever being
operated, and then loosened (turned counterclockwise) 90 - 180
degrees from that point.
Operate lever to change gears, and check that no noise occurs
in any of the gear positions.
For the best SIS performance, periodically lubricate all
power-transmission parts.
Replacement of the freewheel body
After removing the hub
axle, remove the freewheel
body fixing bolt (inside
the freewheel body),
and then replace the
freewheel body.
Note: Do not attempt to
disassemble the
freewheel body, because it
may result in a malfunction.
