CHAIN ½ x 1/8“
It is strongly recommended that a chain solvent is
used to keep the chain clean. Excess dirt built up
on the chain will cause excess wear. A chain
lubricant and solvent for normal road bikes may be
uaed.
Check the lubrication and tension of the chain at
regular intervals. In the middle of its free length the
chain should have a minimum play of 5 mm. See fig
12. When the play in the chain is about 20 mm (<1
inch) the chain must be tightened otherwise it will
cause unnormal wear of the chin and chainwheels.
Because of this it is always recommende to keep
the chain play as little as possible. When the chain
has become so long that it can no longer be tighte-
ned with the chain adjusters it is worn out and shall
be replaced with a new one.
ADJUSTING CHAIN
Remove left and right frame cover. For more info.
see ”RRPLACEMENT of BRAKE BELT”.
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 12.
CHAIN REPLACEMENT
Loosen the chain adjuster as much as possible.
Dismantle the cahinlock and remove the chain. Put
on a new chain and assemble the chain lock.The
spring on 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 13.
Adjust chain adjusters to chainplay according to
above. Tighten axle nuts firmly.
Put on frame covers again.
NOTE:
If the flywheel is not parallel to the centre
line of the frame, the chain will get caught on
the top of the sprocket causeing noise and
damage of the chain.
