REPLACEMENT OF THE
FREEWHEELING SPROCKET
Remove left and right frame cover. For more info see
”REPLACEMENT OF BRAKE BELT”.
Dismantle the chain as described on page 10.
Loosen the axle nuts and remove the flywheel. Remove the
axle nut, washer, chain adjuster and spacer on the
freewheel sprocket side. Place the special remover (part
No. 9100-14) in the adapter and place the spacer and axle
nut outside. See fig 14.
NOTE: Do not tighten the axle nut completely. It must be
possible to loosen the adapter-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 somewhat to make it easier
for the oil to reach the bearing. See fig 15.
CRANK BEARING
The crank bearing is long term greased and needs normally no supplementary lubrication. If problem
arises, please contact your Monark dealer.
FLYWHEEL BEARING
The bearings in the flywheel are lifetime greased and require normally no maintenance. If problem arises,
please contact your Monark dealer.
