I live in Italy and speak fair Italian and have a Ducati IS9. This website is an intellectual property registration - Why it's in French who knows? Ducati don't have any spares for the Diesel and I don't find it easy to get spares or a manual here - I had to by a manual on Ebay. They licensed the design to Wisconsin Diesel WD1-340) in the USA and maybe VM in Italy. The same year of Lombardini is also pretty similar for pumps and injectors. The local Bosch diesel sevice shop here serviced my diesel parts. As I've said before I have a manual for the engine if anyone wants a copy. It is the same Ducati company that now makes motorbikes but they are not helpful for these rare old diesel engines. So it's cut your own gaskets and look at similar sized engines for general spares. Ducati used 'off the shelf' items for a lot of the build.
