Accidental engine starting can cause injury or death to personnel working on the equipment.To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system.Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on.

Fasten Tooling (T1e) to the flywheel so the anvil of Tooling (T1a) will contact the face of the flywheel housing.
Use a rubber mallet and tap the crankshaft toward the rear before the dial indicator is read at each point.

Checking face runout of the flywheel housing
Turn the flywheel while the dial indicator is set at 0.0 mm (0.00 inch) at location (A). Read the dial indicator at locations (B), (C), and (D).
The difference between the lower and higher measurements performed at all four points must not be more than 0.38 mm (0.015 inch). This measurement is the maximum permissible face runout (axial eccentricity) of the flywheel housing.Bore Runout (Radial Eccentricity) of the Flywheel Housing - Check

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 Illustration 5. 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 to put the dial indicator at position (A). Adjust the dial indicator to 0.0 mm (0.00 inch).
Turn the flywheel counterclockwise to put the dial indicator at position (B). Write the measurements in the chart.
Turn the flywheel counterclockwise to put the dial indicator at position (C). Write the measurement in the chart.
Turn the flywheel counterclockwise to put the dial indicator at position (D). Write the measurement in the cha
