8T-5096 Dial Indicator Group
Fasten a dial indicator to the flywheel so the anvil of the dial indicator will contact the bore of the flywheel housing.

While the dial indicator is in the position at location (C), adjust the dial indicator to 0.0 mm (0.00 inch). Push the crankshaft upward against the top of the bearing. Refer to the illustration 7. Write the measurement for bearing clearance on line 1 in column (C) .Note: Write the measurements for the dial indicator with the correct notations. This notation is necessary for making the calculations in the chart correctly.
Divide the measurement from Step 2 by two. Write this number on line 1 in columns (B) and (D) .
Turn the flywheel.
Put the dial indicator at point (A). Adjust the dial indicator to 0.0 mm (0.00 inch).

Checking bore runout of the flywheel housing (A) Bottom. (B) Right side. (C) Top. (D) Left side.
Turn the flywheel counterclockwise in order to put the dial indicator at point (B). Write the measurements in the chart.
Turn the flywheel counterclockwise in order to put the dial indicator at point (D). Write the measurement in the chart.
Add the lines together in each column.
Subtract the smaller number from the larger number in line III in column B and column D. Place this number on line III. The result is the horizontal eccentricity (out of round). Line III in column C is the vertical eccentricity.

Graph for total eccentricity (1) Total vertical eccentricity. (2) Total horizontal eccentricity. (3) Acceptable value. (4) Unacceptable value.
Find the point of intersection of two lines on the graph. One of the lines is the line for vertical eccentricity. The other line is the line for horizontal eccentricity.
The bore is in alignment if the point of intersection is in the range that is marked "Acceptable". The flywheel housing must be changed if the point of intersection is in the range that is marked "Unacceptable".Face Runout (Axial Eccentricity) Of The Flywheel

Checking face runout of the flywheel
Refer to illustration 10 and install the dial indicator. Always put a force on the crankshaft in the same direction before the dial indicator is read. This will remove any crankshaft end clearance.
Set the dial indicator to read 0.0 mm (0.00 inch).
Turn the flywheel at intervals of 90 degrees and read the
