SpectreCodename for Phantom III - Clutch Outboard Bearing, etc. The seizing of the outboard bearing appears to have been due to lack of lubrication. A lubrication scheme has been issued on N. Sch.4111. We now send N.Sch.4134 which also shows a modification to the universal joint splines to increase the area by substituting acme serrations for the square type and more of them. The shaft at present is toughened. it may be necessary to harden the splines and roller race. Da.{Bernard Day - Chassis Design} | ||
