3306 VEHICULAR ENGINE FOR D5B, D6D & D7G TRACTORS – Flywheel Runout

Face Runout (axial eccentricity) of the Flywheel:

Checking Face Runout Of The Flywheel

1. Install the dial indicator as shown. Put a force on the flywheel toward the rear.

2. Set the dial indicator to read 0.0 mm (.00 in)

3. Turn the flywheel and read the indicator every 90°. 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 must not be more than … 0.15 mm (.006 in)

This is the maximum permissible face runout (axial eccentricity) of the flywheel.

Bore Runout (radial eccentricity) of the Flywheel:

Checking Flywheel Bore

1. Install the dial indicator (3) and make an adjustment of the universal attachment (4) so it makes contact as shown.

2. Set the dial indicator to read 0.0 mm (.00 in)

3. Turn the flywheel and read the indicator every 90°.

4. The difference between the lower and higher measurements taken at all four points must not be more than … 0.15 mm (.006 in)

This is the maximum permissible bore runout (radial eccentricity) of the flywheel.

Checking Flywheel Clutch Pilot Bearing Bore

5. Runout (eccentricity) of the bore for the pilot bearing for the flywheel clutch, must not exceed … 0.13 mm (.005 in)
