FRONT CHAINWHEEL: Installation

1. CHOOSING & INSTALLING THE PROPER SPACERPrior 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 accordingly.

SPECIAL TOOLSUse 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.

Use Special Tool TL-FC32 to install the right and left adapter.

Insert the right crank unit. NOTE: Before installing the left-side crank arm, check that there is not gap between the adjustmentnut and the crank arm. (The nut should be fully tightened.) Then, set the left-side crank arm so that the axle of the right-side arm is aligned correctly with the serrations of the left-side crank arm.

Counterclockwise thread for the right and clockwise thread for the left.

General Safety Information

Specifications

Installation of the front chainwheel

WARNING• The fixing bolt for the left-side crank arm must be tightened to 45 – 55 N·m 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 whileriding, resulting in a serious accident.

• Before riding, you should carefully check your crankset to make sure that there are nocracks, and if you find any sign of a crack or any other unusual condition, do NOT usethe 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 thetension is too weak or the chain is damaged, the chain should be replaced. If this isnot 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 forlater reference.

Note• Make sure that the chainring combination matches the front chainwheel tooth

configuration in the Product specifications table. If other combinations are used, thedistance between the chainrings will be incorrect and the chain might slip off and getcaught in between them.

• When the chain is in the position shown in theillustration, the chain may contact the frontchainrings or front derailleur and generatenoise. If the noise is a problem, shift the chainonto the next-larger rear sprocket or the oneafter.

• Before riding the bicycle, check that there is noplay or looseness in the connection. Also, besure 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 bereplaced.

• 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 canbe 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 normaluse.

• For maximum performance we highly recommend Shimano lubricants andmaintenance products.

• For any questions regarding methods of installation, adjustment, maintenance oroperation, please contact a professional bicycle dealer.

Follow the procedure in the figure.1, 2 Use the special tool TL-FC32 to install the right adapter (counterclockwise thread) and the left

adapter (clockwise thread).Tightening torque: 35 - 50 N·m {305 - 435 in. lbs.}

3 Insert the right crank unit.

4 Before installing the left-side crank arm, check that there is no gap between the adjustment nut andthe crank arm (the nut should be fully tightened), and then set the left-side crank arm so that the axleof the right-side crank arm unit is aligned correctly with the serrations of the left-side crank arm.

5 Insert an 8 mm Allen key and turn it clockwise to tighten the crank arm fixing bolt.Note: The crank arm fixing bolt should be periodically retightened.Tightening torque: 45 - 55 N·m {392 - 479 in. lbs.}

6 Use the TL-FC17 to turn the adjustment nut in order to adjust the play, and then tighten theadjustment nut fixing bolt (2.5 mm Allen key).Tightening torque: Adjustment nut / 1 - 1.5 N·m {8.7 - 13 in. lbs.}

Adjustment nut fixing bolt / 1 - 1.2 N·m {8.7 - 10.4 in. lbs.}

7 Turn the TL-FC35 counterclockwise to install the crank arm cap.Note: At the time of shipment from the factory, the crank arm cap is installed to the crank arm, and

so use the TL-FC35 to check that it is securely tightened.

• Be sure to read the service instructions for the Front Drive Systemin conjunction with these service instructions.

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 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.)

Use an 8 mm Allen key and turn it counterclockwise to remove the left-side crank arm.
