| To Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}. from Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} c. By, Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux}16/N.20.6.38. --------------------- Re your memo Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}3/JH.15.6.38. With reference to the Bentley charts, I have enclosed a chart which I trust is clear to you. The top line is the number of clutch complaints. The red line denotes the necessity of changing the complete unit, owing to inaccuracy of the fingers, which causes jagger. These are the unadjustable type. Plates changed. When plates are worn or ( oiled) very seldom, or the fabric causes jagger, the centre plate is changed only. The matter of the rivets being unevenly sunk and in many instances the heads very quickly being in contact with the metal faces of either flywheel or pressure plate was taken up with you, but we have not seen any improvement in this respect.
