The actual cost of replacement of a loose gear ring may not be much less than that of a complete flywheel, since in both cases the flywheel has to be removed. It is, however, easier and there is not the same risk of upsetting the balance of the complete flywheel and crankshaft. We are not clear why it should be necessary to remove the crank shaft with the design proposed, since on the Phantom II car the gear ring can be changed by removing the flywheel only. 5. On older cars we have not stripped the entire engine owing to the cost involved, since it is possible to remove the flywheel in position and ream the holes in the new flywheel without disturbing the crank shaft. On later cars, however, which operate at higher speeds, we have to consider the advisability of balancing the new fly wheel on the old crankshaft, an operation which should not be necessary with a loose gear ring.
