Ducati Diavel Service Manual: Refitting the cylinder head assemblies

Warning

To prevent oil leaks past the contact area between cylinders and crankcase, each time the head is removed, cylinder and piston must be removed as well to clean the mating faces of crankcase and cylinder and restore the spoiled gaskets and o-rings and apply again liquid sealant (sect. 9 - 5, Refitting the cylinder/piston assembly).

Before fitting the head, check that the seal is fitted on the mating surface between head and cylinder (sect. 9 - 5, Refitting the cylinder/piston assembly).

Note

When fitting the gasket, side (e) with the stamped code must be in contact with the cylinder head.

Refitting the cylinder head assemblies


Lower the cylinder head carefully over the studs. Take care not to damage the threads.

Fit the special washers (22) and nuts (21) onto the cylinder head studs.

Tighten the nuts (21) on the stud bolts evenly and gradually in a crosswise pattern using tool 88713.2676 In conjunction with a torque wrench.

Temporary tighten the nuts (21) to a torque of 20 nm; pre-tightening to a torque of 40 nm (min. 38 Nm - max. 48 Nm); one tightening to a torque of 60 nm (min. 57 Nm - max. 63 Nm) (sect. 3 - 3, Engine torque settings).
