VA2/GM.20.10.37 re: PHANTOM III CLUTCHES ----------------------- In order to cure clutch jaggers and also complaints of clutches being very noisy upon engagement, we have fitted cushioned plates to the following chassis :- Chassis 3.AX.185 - Sparrow - Clutch very noisy and jaggered. " 3.BU. 94 - Villeroy- " " " " " " 3.BT.{Capt. J. S. Burt - Engineer} 9 - Schnur - Clutch jaggered. There was a very big improvement after the fitting of the cushioned plates, the clutches were quite silent upon engagement and free from jaggers. We note from your Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}S/AP.IS.8.37 that during July very few long plates of American Manufacture having 9 springs instead of 6 were dispatched. The cushioned plates were sent to us by Works on Aug. 5, 19th, and the 6th. of October. VA.VA- | ||
