2. Divide the measurement from Step 1 by 2. Write this

number on line I in columns (B) & (D).

3. Turn the crankshaft to put the dial indicator at (A).

Adjust the dial indicator to "0" (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 III in columns (B) & (D). The result is the
