Engine
Checking and adjusting the valve clearances
Notes
For clarity, the figures show the engine removed from the frame.
Checking the opening clearance
Move the piston of the cylinder being checked to TDC of the power stroke: in this condition all the valves are closed and the
camshafts are in their rest position and thus free to rotate.
Using a feeler gauge, check the clearance between the opening rocker arm (A) and the lower edge of the camshaft cam (B).
The clearance must be within the specified limits (Sect. C 1.1).
If it is not, remove the opening shim (3), as described in the paragraph “Removal of the valves” (Sect. N 4.5), and replace it with
a shim of adequate height to obtain the specified clearance.
Notes
Opening rocker arm shims measuring 2 to 3.45 are available as replacement parts: each shim is marked with its size.
