1. Rotate the crankshaft in the opposite di­
rection to the normal direction of rotation
through 20° in relation to the fixed refer­
ence. Rotate the crankshaft once again in
its normal direction of rotation until the
same axial movement value which ap­
peared previously on the dial gauge (0.6
mm) appears.
2. Read the angular value on the graduated
disc corresponding to the previous axial
movement (for example 8°). Take the
arithmetical average of the angular value
of the crankshaft set at the beginning of
the procedure (10°) and the current value
(8°), then release the graduated disc from
the base, position it in relation to the fixed
reference, without rotating the crankshaft,
at the value which is the arithmetical aver­
age (for example 9° = the average of 10°
and 8°), then lock the graduated disc once
again.
3. Rotate the crankshaft pulley in a clock­
wise direction until the "0"' on the gradu­
ated disc coincides with the fixed refer­
ence.
4. Rotate the crankshaft through 10° in a
clockwise direction and an anti-clockwise
direction checking that the reading on the
dial gauge during the clockwise rotation
of the crankshaft is the same as that for the
anti-clockwise rotation.
If the readings on the dial gauge after
the check carried out for point 4 are
not the same, repeat the procedure
described on the previous pages.
