Face runout (axial eccentricity) of the Flywheel
I.
Install the dial indicator as shown. Force the
crankshaft the same way before the indicator is
read

clearance
(movement) is always removed.
2.

CHECKING FACE RUNOUT OF THE FLYWHEEL
3.
Turn the flywheel and read the indicator every
90.
4.
The difference between the lower and higher
measurements taken at all four points not be
more than .006 in. (0.15 mm), is the maximum
permissible face runout (axial eccentricity) of the
flywheel.
Bore Runout (radial eccentricity) of the Flywheel
I.
Install the dial indicator (3) and make adjustment
of the universal attachment (4) so it makes
contact as shown.
2.
Set the dial indicator to read .000 in.
3.
Turn the flywheel and read the indicator 90.
4.
The difference between the lower and higher
measurements taken at all four points must not
be more than .006 in. (0.15 mm), 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
.005 in. (0.13 mm).
