Shimano FD-M667 Technical Service Instructions

SI-5KY0A-002-00

General Safety Information

WARNING

• Install a bashguard (165 mm) to the front chainwheel. If the bashguard is

not installed, the chain may come off the chainrings or damage to the

chainrings may occur. If the bashguard used is larger than 165 mm, it

may interfere with the front derailleur and problems with shifting may

occur.

• Be careful not to let the cuffs of your clothes get caught in the chain

while riding, otherwise you may fall off the bicycle.

• Obtain and read the service instructions carefully prior to installing

the parts. Loose, worn or damaged parts may cause the bicycle to fall

over and serious injury may occur as a result. We strongly recommend

only using genuine Shimano replacement parts.

• Obtain and read the service instructions carefully prior to installing

the parts. If adjustments are not carried out correctly, the chain may

come off and this may cause you to fall off the bicycle which could result

in serious injury.

• Read these Technical Service Instructions carefully, and keep them in a

safe place for later reference.

Note

• Turn the top adjustment screw to adjust so that the chain does not sit on

top of the bash guard.

• 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.

• When the chain is in the position shown in the illustration, the chain may

contact the front chainrings or front derailleur and generate noise. If the

noise is a problem, shift the chain onto the next-larger rear sprocket or

the one after.

• For smooth operation, use the specified outer casing and the bottom

bracket cable guide.

• 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.

Installation of the front derailleur

Adjust and then install the front derailleur as shown in the

illustration. Do not remove the Pro-Set alignment block at this time.

With the flat part of the chain guide outer plate on the inside of the

bash guard as shown in the illustration, adjust the height of the front

derailleur so that the outer edge of the bash guard is within the

specified range on the Pro-Set gauge. Also adjust so that the flat

part of the outer plate is parallel to the inner surface of the bash

guard. Use a 5 mm Allen key to tighten.

When installing the components to carbon frame/handle bar

surfaces, verify with the manufacturer of the carbon frame/parts for

their recommendation on tightening torque in order to prevent over

tightening that can cause damage to the carbon material and/or

under tightening that can cause lack of fixing strength for the

SI-5KY0A-002

components.

SIS Adjustment

Be sure to follow the sequence described below.

1. Low adjustment

First remove the Pro-Set alignment block .

Next, set so that the clearance between the chain guide inner

plate and the chain is 0 - 0.5 mm.

Operate lever (B) two times or more,

and check on the indicator that the

lever is at the lowest position. Then

remove the inner hole cover and

connect the inner cable.

Install the inner hole cover by turning it as

shown in the illustration until it stops.

Do not turn it any further than this, otherwise

it may damage the screw thread.

Cutting the outer casing

After cutting the outer casing, make the

end round so that the inside of the hole

has a uniform diameter.

Attach the same outer
