DA.{Bernard Day - Chassis Design}1/G.29.8.38. WALTER BENTLEY 111 - MODIFIED REAR ENGINE SUSPENSION TO REDUCE MOVEMENT OF GEAR CHANGE LEVER. Please receive herewith :- E.CD.854 Engine Rear Suspension - Bentley 111. The main alterations in this design from the existing design G.CD.548 are, the angle of inclination of the torque rubbers, and using the larger rubbers recently instructed for the Wraith 111 in place of the small rubbers at present instructed for the Bentley 111. To get in the larger torque rubbers at the required angle to reduce the engine unit movement at the gear change mechanism by altering the line of engine oscillation, we have had to lower the engine supporting crossmember by .375" which, of course, reduces its ground clearance by this amount. To use in the existing crossmember and engine rear support rubber, we have shown packings to make up the .375" difference between the crossmember and chassis frame and also between support rubber casing and crossmember. Both the bracket on the gear box and also the brackets for torque rubbers on crossmember are new. Will you please detail and instruct experimentally. DA.{Bernard Day - Chassis Design} | ||
