Chain 1/2“ x 1/8“
It is strongly recommended to keep the chain clean.
Dirt build-up on the chain will cause excess wear. A
chain lubricant and solvent for normal road bikes
may be used.
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(3) of 10 mm (1/4
inch). See fig: Chain adjustments. When the play in the
chain is about 20 mm (3/4 inch) it must be tightened
otherwise it will cause abnormal wear of the chain and
chainwheels. Because of this it is always recommended
to keep the chain play as little as possible. Loosen the
hub nut(2) on both sides and tense the chain with the
chain adjuster(1) when needed.
When the chain has become so long that it can no
longer be tightened with the chain adjusters it is worn
out and should be replaced with a new one.
To adjust or replace the chain remove frame covers if
necessary.
To adjust the chain the hub nuts(2) should be
loosened. Loosening or tightening the nuts on the
chain adjusters(1) 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.
To replace the chain, loosen the chain adjuster as much
as possible. Dismantle the chain lock(6) 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(5) of
the chain. Use a pair of tongs for dismantling and
assembling the spring(4). See fig: Chain replacement.
NOTE: At assembly, the flywheel has to be parallel
with the centerline of the frame otherwise the chain
and chain wheels make a lot of noise and wear out
rapidly.
Adjust chain adjusters to allow chain play according
to above. Tighten hub nuts firmly. Replace frame
covers.
