The Works have asked for a means of withdrawing the flywheel hub from the crankshaft. We have shewn two tapped holes. At the same time we have drawn a bush in position, similar to the experimental one now being tried on B.80. We notice that there is a difference in shape between the Vauxhall spring cavities and ours, and theirs seems to be correct. Please instruct experimentally. DA.{Bernard Day - Chassis Design} | ||
