FLYWHEEL RUNOUT
Face Runout (axial eccentricity) of the Flywheel:
1.
Install the dial indicator as shown. Put a force on the
flywheel toward the rear.
2.
Set the dial indicator to read .000 in. (0.0 mm).
3.
Turn the flywheel and read the indicator every 90°. Put a
force on the flywheel to the rear before each reading.
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 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 .000 in. (0.0 mm).
3.
Turn the flywheel and read the indicator every 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).
