Set the engine to the configuration described for the "checking and adjusting the valve clearances", previously indicated.
Position the tool 88765.1518 On the cylinder head: the part marked "a" should be on the intake side and the part marked "s" should be on the exhaust side.
Seat the plate (a) and tighten the screws (b).


Set the opening valve clearance to zero when the camshaft is in its rest position by fitting a feeler gauge between the upper rocker arm and the opening shim.
Lock the dial gauge into the seat of the stand marked "a" and position the fork probe against the face of the closing shim.
Set the dial gauge to zero when the valve is fully closed.
Rotate the intake camshaft so as to allow the intake valves to lift fully.
Check on the dial gauge that the measured value corresponds to the prescribed one (sect. 3 -1.1, Timing system/valves).
Repeat the same operation for the exhaust valves, using the dial gauge in the support seat 88765.1518 With the marking "s".
Refit the components by carrying out the same operations indicated in chapter "checking and adjusting the valve clearances", previously described.
Refit the components removed in the procedure.
