2.
Measure flywheel housing bore concentricity and face runout as follows:
a.
Mount dial indicator base (Figure 7, Item 14) to flywheel assembly (Figure 7, Item 2).
b.
Install one dial indicator (Figure 7, Item 12) perpendicular to flywheel housing bell face and a second
dial indicator (Figure 7, Item 13) against flywheel housing bell bore.
c.
Pry flywheel assembly (Figure 7, Item 2) toward engine block (at six o'clock position) to ensure
endplay is in one direction.
d.
Adjust dial indicators to read zero at 12 o'clock position.
CAUTION
When using hexagon head bolt at front of crankshaft to rotate crankshaft, always turn
bolt clockwise. Serious engine damage may result if bolt becomes loose.
NOTE
Total indicator reading is the maximum negative reading plus the maximum
positive reading. For example, if maximum readings were 0.004 inch
(0.102 mm) and -0.007 inch (-0.178 mm), then runout is 0.011 inch
(0.280 mm).
Maximum total indicator reading must not exceed 0.013 inch (0.330 mm) for
either bore concentricity or face runout.
e.
With assistant rotating front of crankshaft clockwise, record readings at 60 degree intervals (six
readings each for bell bore and face). Pry flywheel assembly (Figure 7, Item 2) toward engine block
before taking each reading.
f.
If bore concentricity or face runout exceeds its maximum limit, remove flywheel housing and check for
foreign material on end plate, flywheel housing, and cylinder block mounting surfaces. Mount end
plate and housing. If either reading is still out of limits, replace flywheel housing (WP 0088).
