Herewith is N Sch.4228 showing the arrangement of the Fabric coupling and also the steel disc coupling in the transmission shaft between the clutch and gear box. We have taken the opportunity of modifying the detachable coupling in the centre of the shaft to reduce the number of bolts used. DA.{Bernard Day - Chassis Design} Encl. N Sch.4228. | ||
