ENGINE ASSEMBLY
❱❘ Installing the camshafts and setting
the valve timing
• Clean and oil the bearings.
• Set the two camshafts and make sure that the
visual marks «FLA» or «FLANGE» are aligned with
the cylinder head gasket plane.

• Screw the eight screws of the camshaft-bearing
cap following the order shown in the picture.
Specified torque of the shaft bearing screws:
18 Nm.
• Remove the TDC 1819 tool.
• Using the ignition rotor, give the crankshaft at
least one full turn and check the valve timing.
❱❘ Checking the valve clearance
• Valve clearance must be checked when the
engine is cold.
• With a shim set, measure the clearance
between the bucket and the camshaft.
Valve clearance
Intake 0.15 – 0.20 mm
Exhaust 0.20 – 0.25 mm
• If clearances are not correct, change the pads
after removing the distribution.
• Remove the cups.
• Measure the pad, replace it in order to obtain
the needed clearance.
For existing pad thickness models refer to the
spare parts catalog.
