| 512. To H.S. from Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler} c. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler}1/MH.{M. Huckerby}2/10/37. CLUTCH 20/25 H.P. We have some metallic clutch facings, and to make comparative tests between these and R.A.D.11. it is proposed to mount Bentley Engine Unit 11 on a test bed, and test a set of each facing to destruction. Please dismantle the clutch of B.11 for examination, and if the facings on driven plate are appreciably worn, fit new ones. After these have been destroyed, fit another new driven plate and graphite Bronze facings instead of the ferodo. Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler} | ||
