Remove left and right frame cover. See ”REPLACEMENT OF BRAKE BELT”.
Dismantle the chain as described on page 9.
Loosen the axle nuts and lift off the flywheel. Remove the axle nut, washer, chain adjuster and
spacer on the freewheel side. Place the special remover (part No. 9100-14) in the adapter and
place the spacer and axle nut outside. See fig 14.

sprocket half a turn.
Replace sprocket-adapter and assemble the new parts in reverse order according to the above.
LUBRICATION SPROCKET
The sprocket should be lubricated with a few drops of oil once a year. Incline the cycle so-
mewhat to make it easier for the oil to reach the bearing. See fig 15.
