X8020 Hs{Lord Ernest Hives - Chair}2/LM16.1.33. SETTING OF SLIPPER FLYWHEELS. X8020 X8300 Referring to the setting of the flywheels which Hs{Lord Ernest Hives - Chair}/CWH. used on the engine of 7-LF car. This setting is not altogether experimental, it closely follows the standard which has been used by Springfield for a considerable time. They have been using xxxx the cotton duck friction surface and the friction adjusted to 170 in.lbs. The actual adjustment on 7-LF as it was left was 153 in.lbs. The present standard adjustment for Phantoms is 350 in.lbs. approximately. Hs.{Lord Ernest Hives - Chair} | ||
