Description of Change: The standard flywheel group and the double inertia flywheel group have a new flywheel assembly.

Adaptable To: The standard 2W-8772 Flywheel Gp now includes the new 243-3219 Flywheel As, which replaces the cancelled 223-0858 Flywheel As .

The double inertia 169-3337 Flywheel Gp now includes the new 276-8812 Flywheel Gp, which replaces the cancelled 162-1501 Flywheel As .

Note: The increased size of the new 276-8812 Flywheel Gp may cause packaging to be a consideration.
