Shimano RD-M410 Service Instructions

General Safety Information
WARNING
• Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any
way, they may come off the bicycle and serious injury may result.
• 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 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 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.
• 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 oil 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.
• Always be sure to use the sprocket set bearing the same group marks. Never
use in combination with a sprocket bearing a different group mark.
• 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.
• 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.
• 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.
• 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.

Best setting
The best setting is when the shifting lever is operated just
enough to take up the play and the chain touches the 3rd
sprocket and makes noise.
* Return the lever to its original position (the position where
the lever is at the 2nd sprocket setting and it has been
released) and then turn the crank arm clockwise. If the chain
is touching the 3rd sprocket and making noise, turn the outer casing
adjustment barrel clockwise slightly to tighten it until the noise stops and
the chain runs smoothly.
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.
