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 900.
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).
