Ph.III, & 25/30 HP. and Ph.II, and 20/25 HP. The Depots find that .003 and .005 oversize are the sizes that are chiefly required. There experience is that wear takes place mostly on the driving dog splines, and that the .003 and .005 represents the wear in the hub splines. Rm{William Robotham - Chief Engineer}/GWH.{George W.
