NOTE: Write the dial indicator measurements with their po-
sitive (+) and negative (–) notation (signs). This notation is
necessary for making the calculations in the chart correctly.
1. With the dial indicator in position at (C), adjust the dial indicator to
“O” (zero). Push the crankshaft up against the top bearing. Write
the measurement for bearing clearance on line 1 in column (C).
2. Divide the measurement from Step 1 by 2. Write this number on line
1 in column (B)& (D).
3. Turn the crankshaft to put the dial indicator at (A). Adjust the dial
indicator to’ ‘O” (zero).
4. Turn the crankshaft counterclockwise to put the dial indicator at
(B). Write the measurement in the chart.
5. Turn the crankshaft counterclockwise to put the dial indicator at
(C). Write the measurement in the chart.
6. Turn the crankshaft counterclockwise to put the dial indicator at
(D). Write the measurement in the chart.
7. Add lines I & II by columns.
8. Subtract the smaller number from the larger number in line Ill in
columns (B) &(D). The result is the horizontal “eccentricity” (out of
round). Line Ill, column (C) is the vertical eccentricity.

9. On the graph for total eccentricity find the point of intersection of
the lines for vertical eccentricity and horizontal eccentricity.
10. If the point of intersection is in the range marked “Acceptable”, the
bore is in alignment. If the point of intersection is in the range
marked’ ‘Not Acceptable”, the flywheel housing must be changed.
