POSITIONING OF STOP CAM ON DESMODROMIC
DEVICE
1) Stop lever;
2) Stop cam;
3) Screw M6x30;
4) Movable pawl return spring.
3.8.2 ASSEMBLY OF EXTERNAL
GEARSHIFT
Keeping the stop lever moved
1
in such a way
that the spring is compressed, position the stop
cam
2
on the protruding end of the desmodro
-
mic gearshift (external right crankcase). The
stop cam has only one correct position which is
determined by the particular shape of the end
of the desmodromic device and of the bottom
part of the stop cam.
Proceed mounting the tightening screw
3
M6x30 between the stop cam and the desmo
-
dromic gearshift, after having applied medium-
resistance sealant: tighten it at 10Nm.
Insert the drive shaft together with the washer
in its seat keeping the return spring
4
of the
movable pawl pressed.
Wishing to test the correct functioning of the
entire unit, you just need to temporarily cou
-
ple the external gearshift lever and to simula
-
te the operation of changing gears, by lifting
and lowering the gearshift lever and having the
mainshaft of the gear unit rotate. The whole de
-
vice works properly if abnormal jamming does
not occur.
If the unit runs without oil, the device makes
more noise than usual.
