START-UP DEVICE
Before reassembling the start-up device you
must perform some important verifications.
TESTING THE IGNITION SHAFT
AND THE ASSEMBLY
To disassemble all components of the igni-
tion shaft you must remove the spring re-
turn lever 11 and spacer 14. Open the See-
ger 23, which allows you to remove all the
other components.
Verify that the sides of the teeth of the start-
up gear 16 do not present any signs of sei-
zing or particular superficial wear-and-tear
and that the front teeth (on the side of slee-
ve 20) do not have any cracks. If so, replace
the component.
Verify that the front teeth of sleeve 20 are
not cracked and that the spring 21 exerts
enough pressure onto the sleeve for wheel
16 to be driven by sleeve 20.
Moreover, verify that all the washers and
shim washers are not abnormally or exces-
sively worn. If so, replace them. Verify that
spring 11 is not cracked or abnormally de-
formed. Should it fail to bring the external
start-up lever back to its idle position, re-
place it.
