TO [REDACTED] FROM AJS. L8310 AJS2/M2.7.25. Copy to - [REDACTED] HS.{Lord Ernest Hives - Chair} EAC. 7. GEARBOX. We send you herewith LeC. 2096., shewing modification to front of W. series 40/50 gearbox to produce the front suspension scheme for EAC. 7. box. The alteration consists in exchanging the 40/50 front bearing housing cover for the steel one indicated on drawing. In order to securely fasten this cover,(which, in addition,acts as a trunnion carrier for the box,)to the casting .312 X .250 studs are used. It has been necessary to turn the cover through 90°, so that the nuts on cover studs will suit the 'Y' bracket, and in this connection it should be noted that the 'Y' bracket always goes with the cover, it being secured by the machine riveted collar on trunnion nose. A further drawing will shew the coup- ling and the attachments. AJS. | ||
