Bore Eccentricity
A—Measure Face Deviation
B—Measure Bore Eccentricity
1. Mount dial indicator on flywheel. Set pointer to contact
PTO mounting surface on flywheel housing at right
angles (A). Pointer should not contact holes in flywheel
housing.
IMPORTANT: Maintain constant end pressure on
crankshaft to hold shaft against thrust
bearing when measuring flywheel
housing face runout.
2. Rotate flywheel by turning crankshaft. Read total dial
indicator movement and compare to specifications.
3. Remount set pointer to contact flywheel housing inner
bore (B).
4. Rotate flywheel by turning crankshaft. Read total dial
indicator movement and compare to specifications.
