Take the cylinder whose clearance has to be adjusted into the
combustion phase; the valves of this cylinder are closed while
they balance the symmetric cylinder valves.
NOTE Thecorrespondenceofthe symmetrical cylin-
dersis1-6,2-5and3-4.
In order to carry out these operations correctly, follow the indi-
cations below in accordance with the indications in the table.
Using a box wrench, loosen the nut (1) locking the adjustment
screw.
Insert the feeler gauge blade (3) corresponding to the operating
clearance indicated in the table “Data and assembly clearance”
in SECTION 7 - Technical specifications.
Use a suitable wrench to screw or unscrew rocker arm (2) adju-
sting screw.
Check that the blade of the feeler gauge (3) can slide with a light
amount of friction.
Lock the nut (1) holding the adjustment screw still.
To carry out the adjustments stated above, the sequence shown
in the table is mandatory.
