" Do you know that in the 24h there are to points in the distribution gear of the crankshsaft? but wich one is the correct, the index point,"el de la chaveta", or the other one. "
____ I understand this to mean to say: that the bevel-gear on the crankshaft of a 24-Horas model, has not only the normal timing-dot, but also an extra mark as well.
Do I understand that correctly?
If so, please post a close-up picture of that crankshaft-bevelgear.
__ The correct timing-dot ought to be located directly aligned with that 21t bevel-gear's key-slot.
Some models have their crankshaft's bevel-gear with it's timing-dot located at 11-o'clock -(actually @ 11:26-o'clock), for use with camshafts that have their key-slot located in a position that's about -(+/- 5) 8.6-degrees advanced, (compared to other camshaft models). (I really can't explain why Ducati did not make them all the same, [perhaps the change had to do with a common production-error with the alignment of the key-slot?].)
Therefore, the timing-dot/mark that should be used (for alignment with the tower-shaft bevel-gear's timing-dot), depends on the camshaft that's installed.
__ If you are not sure which model of camshaft is installed, then I suggest that you try both settings and learn which alignment produces the most compression or best power.
