Chain 1/2“ x 1/8“
It is strongly recommended to keep the chain
clean. Dirt build-up on the chain will cause ex-
cess wear. A chain lubricant and solvent for nor-
mal road bikes may be used.
Check the lubrication and tension of the chain in
regular intervals. In the middle of its free length
the chain should have a minimum play of 10 mm
(1/4 in). See
fig: Chain adjustments
. When the
play in the chain is about 20 mm (3/4 inch) the
chain must be tightened otherwise it will cause
abnormal wear of the chin and chainwheels. Be-
cause of this it is always recommended to keep
the chain play as little as possible. When the
chain has become so long that it can no longer be
tightened with the chain adjusters it is worn out
and shall be replaced with a new one.
To replace the chain remove left and right frame
cover. To adjust the chain the hub nuts should be
loosened. Loosening or tightening the nuts on the
chain adjusters will then move the hub and axle
forward or backward. Adjust according to above
recommendation. Then tighten the nuts on the
hub axle again. See fig: Chain adjustments.
Loosen the chain adjuster as much as possible.
Dismantle the chain lock and remove the chain.
Put on a new chain and assemble the chain lock.
The spring of the chain lock should be assembled
with the closed end in the movement direction
of the chain. Use a pair of tongs for dismantling
and assembling the spring. See fig: Chain repla-
cement.
Adjust chain adjusters to allow chain play accor-
ding to above. Tighten axle nuts firmly. Put on
frame covers again.
NOTE: At assembly the flywheel has to be paral-
lell with the centerline of the frame otherwise the
chain and chain wheels makes a lot of noise and
wears out rapidly.
