EXTERNAL TRANSMISSION
CONTROL
Before reassembling the external transmis-
sion control you should check the wear-
and-tear state of the device. With regards
to the stop cam, simply ensure that there is
no abnormal wear-and-tear and/or seizing,
whereas the gear shaft requires more elabo-
rate verification.
TESTING THE COMPLETE GEAR
SHAFT
With the device completed, verify the distan-
ce between the mobile pawl and the control
shaft falls between 0.70 and 0.90 mm.
If the measurement exceeds this, you must
replace the mobile pawl.
To replace the mobile pawl you must remo-
ve the pawl spring 1 and the return spring
of the transmission control 2. Drill a hole
in zone A with a 5 mm tip for the return
spring pin in which it is riveted until it is
disassembled.
Then rest the new mobile pawl onto the
control shaft 3, insert the new spring return
pin and rivet the excess part of the pin. Re-
mount the pawl spring and the transmission
control spring return.
