1. CHOOSING & INSTALLING THE PROPER SPACER Prior to installation, determine proper spacer configuration. Determine whether the width of the bottom bracket shell is 68mm or 73mm. Then, refer to the illustrations below and install the proper Adapter Adapter adapter accordingly.
Tightening torque : 35 - 50 Nm {305 - 435 in. lbs.}
SPECIAL TOOLS Use Special Tool TL-FC32 (spanner) and TL-FC35 to install the right and left adapter. Use TL-FC17 to turn adjustment nut when adjusting play.
Be sure to read the service instructions for the Front Drive System in conjunction with these service instructions.

Counterclockwise thread for the right and clockwise thread for the left.
Tightening Torque:
Insert an 8 mm Allen key and turnInformation it clockwise to tighten the General Safety crank arm fixing bolt. NOTE:The crank arm fixing bolt should be retightened periodically.WARNING
The fixing bolt for the left-side crank arm must be tightened to 45 55 Nm using a torque wrench. After the bicycle has been ridden for approximately 100 km (60 miles) or in the event of a crash, the fixing bolt should be rechecked using a torque wrench. Inadequate tightening of the fixing bolt could cause the crank arm to fall off while riding, resulting in a serious accident. Before riding, you should carefully check your crankset to make sure that there are no cracks, and if you find any sign of a crack or any other unusual condition, do NOT use the bicycle. Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you may fall off the bicycle. 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 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
Make sure that the chainring combination matches the front chainwheel tooth configuration in the Product specifications table. If other combinations are used, the distance between the chainrings will be incorrect and the chain might slip off and get caught in between them. When the chain is in the position shown in the Front illustration, the chain may contact the front chainrings 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 Rear after. sprockets Before riding the bicycle, check that there is no play or looseness in the connection. Also, be sure to retighten the crank arm fixing bolt at periodic intervals. (BB-FC, FC-PD) If you feel any looseness in the bottom bracket axle, the bottom bracket should be replaced. In addition, if pedaling performance does not feel normal, check this once more. Do not wash the bottom bracket with high-pressure jets of water. Apply grease to the bottom bracket before installing it. To ensure the best performance, be sure to use only the specified type of chain. The wide type of chain cannot be used. If the chain keeps coming off the chainrings during use, replace the chainrings and the chain. You should periodically wash the chainrings in a neutral detergent and then lubricate them again. In addition, cleaning the chain with neutral detergent and lubricating it can be an effective way of extending the useful life of the chainrings and the chain. 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.

Turn clockwise Turn the TL-FC35 clockwise to remove the crank arm cap. NOTE: The crank armcap and the TL-FC35screw have a left-hand (reverse) thread. This is to prevent the crankarm from turning as you remove the crank arm fixing bolt.
Turn counterclockwise Turn the TL-FC35 counterclockwise and tighten it as far as it will go. Make sure it turns at least 3.5 times or more.(If fewer than 3.5 threads are engaged, then there is a higher possibilty that the threads will strip.)
