WRAITH 111 - FRONT HIGH ENGINE MOUNTING. As requested by Rm {William Robotham - Chief Engineer} /Wym. {G. Harold Whyman - Experimental Manager} we attach two prints of a rough sketch of the front engine support member suitable for the offset nose bearing, for replacing the previous engine support, using a tubular frame crossmember. We understand that 26-G-1V. is to have this mounting fitted. All particulars for the lower portion of the member are shown in full on E.CD.61 drawing, although it will be necessary to adapt the bracket fixings to side frames to the existing bolts used for the tubular crossmember. The adaption of the offset nose bearing to the existing facing on cylinder block was shown on a previous rough sketch issued to you. The reason the amount of offset is called for as 1.875" is, because we are proposing this figure as a common offset for both Wraith 111 and Bentley 111 cars, Rm. {William Robotham - Chief Engineer} has agreed to this figure. The final designs for both Wraith 111and Bentley 111 are being made to suit this amount of offset. DA. {Bernard Day - Chassis Design} | ||
