User manual SHIMANO WH-7900-C35-CL ASSEMBLY

[. . . ] With these types of forks, the clearance between the hub axle and the brake shoes can change due to the operation of the suspension, so that when the brakes are applied, the brake shoes may touch the spokes. If the quick release mechanism is not used correctly, the wheel may come off the bicycle and serious injury could result. Read the Service Instructions for the quick release mechanism thoroughly before use. These wheels are designed for riding on paved surfaces. If the wheels are used on unpaved surfaces, the wheels may become bent or damaged, and accidents may result. [. . . ] Use rim tape which can withstand high pressures, otherwise the tires may suddenly puncture and come off, and severe injury may result. Sprocket tooth configuration Installation of the HG sprockets For each sprocket, the surface that has the group mark should face outward and be positioned so that the wide parts of the gear projections on each sprocket and the A part (where the groove width is wide) of the freewheel body are aligned. A Wide part ac-14T 11T - 21T, 11T - 23T NOTICE The Shimano R55HC (high performance) brake shoes use an aggressive compound designed with an emphasis on maximum performance in wet conditions, however they will cause accelerated rim wear. Shimano accepts no responsibility for reduced rim life which might occur from using R55HC brake shoes. Use of genuine Shimano spokes and nipples is strongly recommended. If non-Shimano parts are used, the area where the spokes fit into the hub unit may become damaged. Before use, check that there are no pieces of metal or other foreign objects sticking to the brake pads. If any such items are present, they may cause damage to the rim when the brakes are applied. The nipples have large diameters and are easy to rotate in order to make it easier to increase the spoke tension. However, be careful not to overtighten the nipples when adjusting the spoke tensions. If the nipples are overtightened, damage to the rim may result. (We recommended that you ask authorized bicycle dealers to make the adjustments. ) Replacing the spokes Hook the spokes through the hub as shown in the illustration to install them. At the front, fit the heads of the spokes securely into the slots in the hub unit, otherwise damage may occur. *1 Inner ring For installation of the HG sprockets, use the special tool (TL-LR15) to tighten the lock ring. Tightening torque: 30 - 50 N·m {261 - 435 in. lbs. } To replace the HG sprockets, use the special tool (TL-LR15) and TL-SR21 to remove the lock ring.

When installing the CS-7900 (10-gears) freehub, install a spacer in the position shown in the illustration.

Do not apply any oil to the inside of the hub, otherwise the grease will come out. Special spoke wrenches are available as optional accessories. We recommend that you ask authorized bicycle dealers to adjust the spoke tensions if there is any initial play in the spokes and after the first 1, 000 km of riding. Spoke protectors (CP-WH23) are also sold separately. Please ask your bicycle dealer for details. [. . . ] (English) After removing the hub axle, remove the freewheel body fixing bolt (inside the freewheel body), and then replace the freewheel body. Tightening torque: 45 - 50 N·m {392 - 435 in. lbs. } Note: When replacing the freewheel body, replace the freewheel body fixing bolt at the same time. Be sure to apply grease to the the thread of the freewheel body fixing bolt, otherwise looseness or sticking may occur. [. . . ]
