| EFC {E. Fowler Clarke - Electrical Engineer} 2/AD20.8.30 contd. -4- circumstances and any kind of failure or unsatisfactoriness and the cause or causes of these noted. In this particular case this went through completely satisfactorily. There was no failure to engage other than corner jamming which was only very occasional. It appeared to be less frequent than with the standard combination, though since in the standard combination the engaging corners of pinion and gear teeth are likewise sharp there seemed no reason for any difference in this respect. (8) In this test it is ascertained whether the pinion disengages satisfactorily when the crankshaft is rotating at a relatively high speed. It was found that dis-engagement was effected quite satisfactorily without any hesitation but it will be remembered that on this rig we are unable to reproduce exactly the rapid flywheel acceleration due to the engine. (9) The flywheel gear ring and motor pinion were now removed for further examination and their condition was not found to be appreciably different from that observed after test (2) (3) (4) and (5). This would appear to confirm that the majority of the burring was caused by the high voltage test. | ||
