| TO BY FROM AJS. Copy to - CL " " HS.{Lord Ernest Hives - Chair} ORIGINAL AJS2/M4.12.25. X3829 X3159 RR. E.16. DIRECT DRIVE NOSE AND THRUST BEARING. The results of the thrust tests on the New Departure bearing No.215. recently made by HS.{Lord Ernest Hives - Chair}, and a discussion with Col. Fell regarding the thrusts taken by propellers in practice bears out our belief that bearing No.215. can be used in place of bearing No.313. for the thrust bearing for direct drive on the above engine. (SENT TO BY.{R.W. Bailey - Chief Engineer} FRIDAY LAST) In view of this we send you herewith drawing LeC. 2177. shewing modifications required to the shaft and bearing housing to enable bearing No. 215. to be incorporated on the same lines as No.313. was previously. The aforegoing modifications will considerably lighten the whole job. AJS. SH RECEIVED 10 DEC 1925 | ||
