If the light turns on during braking, at idling speed or while turning a corner, it is necessary to
check the oil level and the lubrication system.
Checking the ignition timing
-Remove the 4 fixing screws and move away from
the engine the flywheel cover fitted with a water
pump and cooling manifolds.
-Rotate the flywheel until the reference matches
the crankcase operation end as shown in the figure
(TDC). Make sure that the 4V reference point on
the camshaft control pulley is aligned with the ref-
erence point on the head as shown in the second
figure. If the reference mark is opposite the indi-
cator on the head, make the crankshaft turn once
more.
-The TDC reference mark is repeated also be-
tween the flywheel cooling fan and the flywheel
cover.
To use this reference mark, remove the spark plug
and turn the engine in the opposite direction to the
normal direction using a calliper spanner applied
to the camshaft command pulley casing.
N.B.
TIME THE TIMING SYSTEM UNIT IF IT IS NOT IN PHASE.
Checking the valve clearance
-To check valve clearance, centre the reference
marks of the timing system
- Use a thickness gauge to check that the clear-
ance between the valve and the register corre-
sponds with the indicated values. When the valve
clearance values, intake and drainage respective-
ly, are different from the ones indicated below,
adjust them by loosening the lock nut and operate
on the register with a screwdriver as shown in the
figure.
Intake: 0.10 mm (when cold)
