APPET BACKLASH
After the first 300÷1000 mi and after evey 6000 mi, or
when the timing system becomes very noisy, check the
backlash between the valves and the equalizers.
Adjustment must be carried out when the engine is coil
, with the piston at top dead center (T.D.C), in compression
stage (valves closed).
Work as follows:
• Remove the head cover "A" by unscrewing the eight
screws"B"
• Loosen the nuts "C";
• Loosen or unscrew the adjustment screw "D" until you
obtain the following backlashes:
- Intake valve 0,10 mm;
- Exhaust valve 0,15 mm
This measurement is effected by inserting a feeler gauge
"E" between the rocker and the valve.
Remeber that if the backlash is greater than the prescribed
one, the tappets will be noisy. If it is less, the valves will
not close well, thereby causing the following problems:
• Loss of pressure;
• Engine overheating;
• Valve burning-out, etc
