Ducati SUPERBIKE 848 MY 2008 Manual page 510

Cylinder/piston assemblies
Remove the bushes (12).
Use service tool no. 88765.1523 to bring the piston of the horizontal cylinder to TDC.
Carefully lift the cylinder barrel (10) off the crankcase, keeping it vertical.
If necessary, rock the cylinder slightly using both hands or tap its base gently with a rubber mallet. Continue to lift
the cylinder until you can access the gudgeon pin (3).
Notes
For better sealing, the piston ring gaps should be positioned at 180° intervals.
Since insertion of piston in the barrel is a difficult operation to perform at the time of reassembly, remove the piston
together with the barrel as described below.
Stuff the crankcase opening with a rag or soft paper to prevent foreign material from falling in.
