Do not operate or work on this engine unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Caterpillar dealer for replacement manuals. Proper care is your responsibility.
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.

Install Tooling (T1c) onto the flywheel housing with Tooling (T1a), (T1d), and (T1e). 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 dial indicator.
Take the measurements at all four points. Find the difference between the lower measurements and the higher measurements. This value is the runout. The maximum permissible face runout (axial eccentricity) of the flywheel must not exceed 0.15 mm (0.006 inch).Bore Runout (Radial Eccentricity) of the Flywheel - Check

Install Tooling (T1c) onto the flywheel housing with Tooling (T1a), (T1d), and (T1e). Make an adjustment of Tooling (T1b) so that the dial indicator makes contact on the flywheel.
Set the dial indicator to read 0.0 mm (0.00 inch).
Turn the flywheel at intervals of 90 degrees and read the dial indicator.
Take the measurements at all four points. Find the difference between the lower measurements and the higher measurements. This value is the runout. The maximum permissible bore runout (radial eccentricity) of the flywheel must not exceed 0.15 mm (0.006 inch).Bore Runout (Radial Eccentricity) of the Flywheel Clutch Pilot Bearing Bore - Check
