Make reference to Flywheel Runout for the correct method of flywheel inspection.(1) Gear. Maximum temperature for installation-install with chamfer toward outside ... 316°C (600°F)(2) Torque for the bolts that hold the flywheel to the crankshaft ... 270 40 N m (200 30 lb ft) Put engine oil on threads and face of bolts before assembly.(3) Maximum permissible change from an exact vertical face (runout) during one rotation (total indicator reading) ... 0.43 mm (.017 in)Flywheel Runout
Face Runout (axial eccentricity of the Flywheel):
Checking Face Runout Of The Flywheel1. Install the dial indicator as shown. Put a force on the flywheel toward the rear.2. Set the dial indicator to red 0.00 mm (.000 in).3. Turn the flywheel and read the indicator every 90 degrees. Put a force on the flywheel to the rear before each reading.4. The difference between the lower and higher measurements taken at all four points is the face runout (axial eccentricity) of the flywheel. Make reference to Flywheel to find the maximum permissible runout for a particular flywheel.
