Ducati Diavel Service Manual: Checking and adjusting the valve clearances
Note
For clarity, the figures show the engine removed from the frame.
Move the piston of the cylinder being checked to tdc of the power stroke: in this condition, all the valves are closed and the timing shafts come in neutral position and, therefore, free to rotate; check to the valve clearance on the cylinder head on which it operates.
Checking the opening clearance
Using a feeler gauge, check the clearance between the opening rocker arm (a) and the lowest point of the camshaft lobe (b), taking care not to compress the rocker arm return spring.
The value must be within the specified ones (sect. 3 - 1.1, Timing system/valves).
If not, remove the opening adjuster (3), as described in paragraph "removing the valves" (sect. 9 - 4.5), And replace it with one of suitable height to obtain the prescribed clearance.
Note
Opening rocker arm shims measuring 1.80 To 3.45 Are available as replacement parts: the size is punched on the shim.
Checking the closing clearance
Using a feeler gauge, check the clearance between the closing rocker arm (c) and the highest point of the camshaft lobe (d).
The value must be within the specified ones (sect. 3 - 1.1, Timing system/valves).
If not, remove the closing adjuster (1), as described in paragraph "removing the valves" (sect. 9 - 4.5), And replace it with one of suitable height to obtain the prescribed clearance.
Note
Closing rocker arm shims measuring from 2.2 To 4.5 Are available as replacement parts: the size is punched on the shim.
