Shaft and coupler only. Slinger available in more expensive set, see in the store.
These parts are suitable and required to run a tachometer drive on your bevel single or early twin. Why did Ducati design it this way? Who knows? But here they are.
NOTE: This kit should be suitable for all singles and first generation 750s with separate, roll-pin-retained drive. If your tachometer drive housing is cast integral with the gear cover, this setup will NOT work for you.
Ducati's part numbers are 0420-98-030 for the shaft, 0022-49-240 for the sleeve.
I will answer questions promptly, good luck and thanks for looking.
