ADJUSTMENT OF CHAIN TENSION (SMM)
Loosen both the locking screws (1) of the rear eccentric hub in a way
that the hub itself can turn around its axis.
Using the relevant TM tool, code F50806 (2), turn the hub until correct
chain tension is reached. Tighten the two locking screws to 30 Nm.
Since the movement is an eccentric system, alignment of the rear wheel
is unvaried and no further adjustment is required.
At the same time, by turning the hub a slight variation in the height of the
rear wheel axle may be verified and consequently of the rear part of the
motorcycle. It is possible to compensate this, by varying the projection
of the fork legs from the upper clamp.
For example, if the motorcycle, by effect of chain adjustment, has lifted
by 5mm. at the rear, it is advised to decrease the projection of the fork
rods by about 5mm. to also raise the front and restore the original level -
ling of the motorcycle.
It is advised to use the TM tool, code F50806, pairing with two M8 screws
and two nuts to turn the hub inserting the two screws into the two holes
in the hub itself.
ATTENTION
- IF YOU DO NOT HAVE SUITABLE EXPERIENCE, IT IS ADVISED TO HAVE
THE OPERATION CARRIED OUT BY A SPECIALISED TM WORKSHOP.
CHAIN MAINTENANCE
Chain duration depends most of all on maintenance. Chains without O-
rings must be regularly cleaned with petroleum and then immersed in
warm chain oil or treated with chain spray. Maintenance of chains with
O-rings is reduced to a minimum. The best cleaning method is using
lots of water. Never use brushes or solvents to clean the chain. When
the chain is dry, use a chain spray that is especially suitable for chains
with O-rings.
DO NOT ALLOW THE LUBRICANT TO REACH THE REAR TYRE OR THE
BRAKE DISC, OTHERWISE ADHERENCE TO THE GROUND OF THE REAR
WHEEL AND REAR BRAKE ACTION COULD BE NOTABLY REDUCED AND
IT COULD BE EASY TO LOOSE CONTROL OF THE MOTORCYCLE.
WARNING
ON MOUNTING THE CHAIN SPLIT LINK, THE CLOSED PART MUST BE IN
THE DIRECTION OF MOVEMENT.
Always check both engine and rear wheel sprockets and drive slider for
wear. If necessary, replace these parts.
