ENGINE CHECKS AND ASSEMBLY
3.6.2 EXTERNAL GEARSHIFT AS-
SEMBLY
If you want to test the correct operation of the
entire unit, you just need to temporarily couple
the external gearshift lever and to simulate the
operation of changing gears, by lifting and lower-
ing the gearshift lever and having the main shaft
of the gear unit rotate. The whole device works
properly if no abnormal jamming occurs.
If the unit runs without oil, the device makes
more noise than usual.
Rotate the gear stop lever 1 clockwise so that the
spring is compressed. To keep the lever in this
position, an aluminium rod A can be inserted into
the small hole, as shown in the figure.
Apply the gear stop cam 2 to the protruding end
of the desmodromic control. The stop cam has
only one correct position, which is determined by
the specific shape of the end of the desmodromic
device and of the bottom part of the stop cam.
Next, fit the M6x30 tightening screw 3 between
the stop cam and the desmodromic control, after
applying medium-resistance threadlocker: tighten
at the indicated torque.
Remove the rod A.
Insert the drive shaft together with the specific
washer in its seat whilst keeping the return spring
4 of the movable pawl pressed.
