Install the attachment to the flywheel housing.
Install the gauge on the attachment.
Install the contact tip of the indicator against the inside diameter of the flywheel bore, and set the dial indicator to ‘‘0.’’
Rotate the crankshaft one complete revolution.
NOTE: The total indicator runout (T.I.R.) must not exceed 0.127 mm [0.0050-inch].
If the T.I.R. is greater than the specification, remove the flywheel.
Inspect the flywheel mounting surface for dirt or damage.
Inspect the crankshaft for dirt or damage. Replace the crankshaft if necessary.
Install the flywheel, and inspect the bore runout again.
Replace the flywheel if the runout does not meet specifications.
Face Alignment – Measurement
Install the contact tip of the indicator against the flywheel face, as close to the outside diameter as possible, to inspect the face (4) runout.
Push the flywheel forward to remove the crankshaft end clearance. Adjust the dial on the indicator until the needle points to ‘‘0.’’
Rotate the crankshaft one complete revolution. Measure the flywheel runout at four equal points on the flywheel.
NOTE: The flywheel must be pushed toward the front of the engine to remove the crankshaft end clearance each time a point is measured.
