| H.P.C. This is interesting. We should try & confirm the results in conjunction with the repair dept To Hs.{Lord Ernest Hives - Chair}. from Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} c. to By.{R.W. Bailey - Chief Engineer} c. to Rm.{William Robotham - Chief Engineer} c. to Mx.{John H Maddocks - Chief Proving Officer} fil 1110. (25/30 HP. & Bentley Clutches.) 20/25 3 1/2 Cricklewood have had a recurrent complaint of Clutch jagger with the lead bronze type facing. This has been cured by the fitting of a new bronze bush bearing in the clutch plate housing. A fabric plate clutch of the same type has also been cured. In both cases it was noticed that there was considerable slackness in this bearing, which would allow chattering to take place. The results after fitting the new bush were so pronounced that any further complaints will be dealt with by this method. Rm{William Robotham - Chief Engineer}/ GWH.{George W.
