Checking the closing clearance (Sc) of the intake/exhaust valves
To check the valve closing clearance, insert a feeler gauge between the closing rocker (D) and the shim (1): the closing
clearance (Sc) corresponds to the thickness of the feeler gauge and should allow the free rotation of the shim without any
significant play.
The value must be within the prescribed ones (Sect. 3 - 1.1,
Timing system/valves).
If not, remove the closing shim (1), as described in chapter “
Removal of the rocker arms, shims and valves”, Sect. 9 -
4.4, and replace it with one of suitable height to obtain the prescribed assembly clearance.
Note
Closing rocker arm shims measuring from 2.2 to 4.5 are available as spare parts: the size is punched on the shim.
Refit the opening and closing shims as described in the paragraph “
Refitting of the rocker arms, shims and valves“,
Sect. 9 - 4.4.
