Ducati Diavel Service Manual: General maintenance indications
Useful tips
Ducati recommends that you follow the instructions below in order to prevent
problems and obtain the best end result:
- When diagnosing faults, primary consideration should always be given to
what the customer reports about motorcycle
operation since this information can highlight anomalies; your questions to
the customer concerning symptoms of the
fault should be aimed at clarifying the problem;
- Diagnose the problem systematically and accurately before proceeding
further. This manual provides the theoretical
background for troubleshooting; this basis must be combined with personal
experience and attendance at periodic
training courses held by ducati;
- Repair work should be planned carefully in advance to prevent any
unnecessary downtime, for example obtaining the
required spare parts or preparing the necessary tools, etc.;
- Limit the number of operations needed to access the part to be repaired.
Note that the disassembly procedures in this
manual describe the most efficient way to reach the part to be repaired.
General advice on repair work
- Always use top quality tools. When lifting the motorcycle, only use
devices that comply fully with the relevant european

ideally in the order required, and never put them
on the motorcycle or in hard-to-reach or inaccessible places.
- The workplace must be kept clean and tidy at all times.
- Always replace gaskets, sealing rings and split pins with new parts.
- When loosening or tightening nuts or screws, always start with the

the time of reassembly.
