G.CD.1034 CLUTCH ACTUATION - 10" C.F. CLUTCH. This scheme supersedes G.CD.1019. It accommodates the changes in clutch casing design shown on G.CD.1028, and shows a 10" C.F. clutch with the B.111 release mechanism G.CD.891. Should it become necessary to revert to the Wraith 111 Flywheel and Clutch on this car, the above actuation can still be used. The 1st. Motion Shaft of the gearbox is strengthened in accordance with GW.2204, so that the same clutch centre and ball bearing are used. DA.{Bernard Day - Chassis Design} | ||
