Flywheel Runout
Face Runout (Axial Eccentricity) Of The Flywheel:
Checking Face Runout Of The Flywheel (Typical Example)
1.
Install the dial indicator as shown. Put a force on the
flywheel toward the rear.
2.
Set the dial indicator to read 0.0 mm (.000 in).
3.
Turn the flywheel and read the indicator every 90
degrees. 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 0.15 mm (.006 in) which is the maximum
permissible face runout (axial eccentricity of the
flywheel).
Bore Runout (Radial Eccentricity) Of The Flywheel:
Checking Bore Runout Of The Flywheel
(1) 7H1945 Holding Rod. (2) 7H1645 Holding Rod.
(3) 7H1942 Indicator. (4) 7H1940 Universal Attachment.
Checking Flywheel Clutch Pilot Bearing Bore (Typical
Example)
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 0.0 mm (.00 in).
3.
Turn the flywheel and read the indicator every 90
degrees.
