Beginning with the 1300cc engine, a groove was cut *inside* the
hub of the flywheel. An O-Ring slips in the groove and seals the
flywheel hub to the crankshaft. On earlier engines, sealing was
done with paper or metal gaskets between flywheel and crank.

As Bill noted, the O-Ring is often received damaged or gets damaged
when the flywheel is installed on the crank. The O-Ring has to be
installed with care. Use of lubricant will help prevent distortion.
