10.
On the graph for total eccentricity, find the point of
intersection of the lines for vertical eccentricity and
horizontal eccentricity.
11.
If the point of intersection is in the range marked
"Acceptable", the bore is in alignment. It the point of
intersection is in the range marked "Not Acceptable",
the flywheel housing must be changed.
Graph For Total Eccentricity
Face Runout (Axial Eccentricity) Of The Flywheel
1.
Install the dial indicator as shown. Always put a force
on the crankshaft in the same direction before the
indicator is read so the crankshaft end clearance
(movement) is always removed.
Checking Face Runout Of The Flywheel
(Typical Example)
2.
Set the dial indicator to read "0" (zero).
3.
Turn the flywheel and read the indicator every 90
degrees.
4.
The
difference
between
the
lower
and
higher
measurements taken at all four points must not be more
than 0.15 mm (.006 in), which is the maximum
permissible face runout (axial eccentricity) of the
flywheel.
Bore Runout (Radial Eccentricity) Of The Flywheel
1.
Install the dial indicator (3) and make an adjustment of
the universal attachment (4) so it makes contact as
shown.
2.
Set the dial indicator to read "0" (zero).
3.
Turn the flywheel and read the indicator every 90
degrees.
4.
The
difference
between
the
lower
and
higher
measurements taken at all four points must not be more
than 0.15 mm (.006 in), which is the maximum
permissible bore runout (radial eccentricity) of the
flywheel.
5.
Runout (eccentricity) of the bore for the pilot bearing for
the flywheel clutch, must not exceed 0.13 mm (.005 in).
