The countershaft has the task of balancing a part of
the inertial forces produced by the crank mechanism.
The countershaft is mainly made up of the shaft 1 and
counterweight 2. The elastic washer 7 and nut 8 have
the task of assuring coupling of the complete shaft to
the base.

In order to disassemble the shaft, remove the nut
8 which can be accessed through the ignition unit
compartment. Extract the elastic washer 7 and the
counterweight.
