The tension of the chain should allow a play of
approximately 10-15mm in the area between the
swinging arm and the slack adjusting bolt.
To tighten the chain, first loosen the rear axle nut
and then adjust the chain with the drive chain
slack adjusting bolt located on the swing arm.
When adjusted, tighten the nut on the rear axle,
making sure that the chain is aligned and not twis-
ted.
You need to carry out this adjustment with care, as
a rear wheel axle that is misaligned or has a screw
not tightened sufficiently could cause an accident.
Keep the chain lubricated for smooth operation,
preferably using viscous oil for longer life. It is also
important to lubricate the shaft and the nut.
DRIVE CHAIN
a) Drive chain
The drive chain slack adjusting bolt is located on
the sides of the swinging arm. Using the adjusting
bolt you can obtain the right chain slack, making
sure to adjust both sides evenly for correct wheel
alignment.
b) Once you have adjusted the chain to the right tension, tigh-
ten up the axle.
c) Connecting link.
It is important to assemble the connecting link ca-
refully. The closed end must point in the direction
of chain rotation so that it doesn’t fly off if the chain
is hit by a stone. Also, keeping the chain clean and
lubricated prolongs the life of the drive pinion and
sprocket. After the chain has been tightened multi-
ple times, it will need to be replaced.
