3.1.5
Check flywheel face runout.
Mount the indicator base on the flywheel housing and position the dial indicator tip so that its
movement is perpendicular to the face of the flywheel. Position the indicator tip near the drive
ring mounting bolt circle diameter. Rotate the flywheel 360 degrees applying force to the
crankshaft thrust bearing.
The total indicator reading should not exceed 0.0005 inches (0.013 mm) per inch of measured
diameter.
3.1.6
Check engine crankshaft endplay
.
Measure and document the engine’s crankshaft endplay before installing PTO. Using dial
indicator as shown in 3.1.5 force the crankshaft back against the rear main bearing and then force
the crankshaft to the front of the engine. Record the total movement as shown by the dial
indicator.
3.1.7
Check engine radial play.
Apply upward radial force by using a prybar to check the radial play in flywheel. Consult engine
manufactures specifications to ensure correct tolerance.
3.1.8
Check flywheel pilot bore runout.
Mount the indicator base on the flywheel housing and position the dial indicator tip so its
movement is perpendicular to the pilot bore diameter, to measure pilot bore runout. Rotate the
flywheel through 360 degrees.
The total indicator reading should not exceed 0.005 inches (0.127 mm).
