| EFC2/AD20.8.30 contd. -5- In order to reduce the initial burring over of the flywheel gear teeth edges it would appear advisable to have the flywheel gear teeth harder. This is more particularly the case in view of the fact that the possibility of chipping occurring on disengagement, as on the standard combination, would be largely obviated. From the above tests it appears well worth while to fix up an experimental chassis with this combination preferably with rather harder flywheel gear teeth. The advantages may be said to be (a) Reduction in manufacturing cost. (b) Reduced tendency for chipping of teeth on disengagement together with less burring upon engagement. (c) More reliable engagement generally. As previously stated, this test was only carried out as a preliminary to possible further steps, but the result has been so relatively satisfactory as definitely to warrant a test on a car of this arrangement without further modification. We can therefore confidently recommend such a test being made. Further to the above, we are of the opinion that it would be an advantage at this stage experimentally | ||
