Face Run Out (Axial Eccentricity) Of The Flywheel Housing
8T5096 Dial Indicator Group Installed (Typical Example)If any method other than given here is used, always remember bearing clearance must be removed to get correct measurements.1. Fasten a dial indicator to the flywheel so the anvil of the indicator will touch the face of the flywheel housing.2. Put a force on the crankshaft toward the rear before the indicator is read at each point.

The difference between lower and higher measurements taken at all four points must not be more than 0.38 mm (.015 in), which is the maximum permissible face run out (axial eccentricity) of the flywheel housing.Bore Runout (Radial Eccentricity) Of The Flywheel Housing
1. Fasten the dial indicator as shown so the anvil of the indicator will touch the bore of the flywheel housing.2. With the dial indicator in position at (C), adjust the dial indicator to "0" (zero). Push the crankshaft up against the top of the bearing. Write the measurement for bearing clearance on line 1 in column (C) in the Chart For Dial Indicator Measurements.
8T5096 Dial Indicator Group Installed (Typical Example) Write the dial indicator measurements with their positive (+) and negative (-) notation (signs). This notation is necessary for making the calculations in the chart correctly.3. Divide the measurement from Step 2 by 2. Write this number on line 1 in columns (B) & (D).4. Turn the flywheel to put the dial indicator at (A). Adjust the dial indicator to "0" (zero).5. Turn the flywheel counterclockwise to put the dial indicator at (B). Write the measurements in the chart.

Turn the flywheel counterclockwise to put the dial indicator at (D). Write the measurement in the chart. 8. Add lines I & II by columns.9. Subtract the smaller number from the larger number in line III in columns (B) & (D). The result is the horizontal eccentricity (out of round). Line III, column (C) is the vertical eccentricity.10. On the graph for total eccentricity, find the point of intersection of the lines for vertical eccentricity and horizontal eccentricity.11. 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.

1. Install the dial indicator as shown. Always put a force on the crankshaft in the same direction before the indicator is read so the crankshaft end clearance (movement) is always removed.
Checking Face Runout Of The Flywheel (Typical Example)2. Set the dial indicator to read "0" (zero).3. Turn the flywheel and read the indicator every 90 degrees.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

(1) 7H1945 Holding Rod (2) 7H1645 Holding Rod (3) 7H1942 indicator (4) 7H1940 Universal Attachment1. 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" (zero).3. Turn the flywheel and read the indicator every 90 degrees.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 bore runout (radial eccentricity) of the flywheel.5. Runout (eccentricity) of the bore for the pilot bearing for the flywheel clutch, must not exceed 0.13 mm (.005 in).
