Checking flywheel contact surface
1. Check the contact surface for visible cracks or damage.
– If damaged, the flywheel may be turned down until the indicator groove on the outer circumference of the contact surface is no longer visible. This corresponds to a maximum of 2 mm [0.08 in].
– Cracks are not allowed:
Within 5 mm [0.2 in] of the outer edge.
In the contact surface, deeper than 2 mm [0.08 in].
Checking flywheel run-out
1. Clean the flywheel.
2. Place a metal strip on the edge of the flywheel housing to fit a dial gauge.
3. Place the stylus of the dial gauge at the specified radial distance from the center line.
4. Set the dial gauge to ‘0’.
5. Use the special tool (1903018) to crank the engine through 360°, and measure the maximum dial gauge reading.
6. Compare the measured value with the specified data.
