| X. 3455 To WHC. from E.{Mr Elliott - Chief Engineer} E.1/HP.19.11.32. C. for. Hs.{Lord Ernest Hives - Chair} Bv. Ea. Fw/MY. re Experimental Bensport Chassis with existing Japan 1 unit. We send you herewith an advance print of Lec.3280 showing the amount of information available uptodate for assembling the above. This drawing in particular deals with a modification necessary to the pedals. The position of the standard pedals on the unit would be too high and we have had to shorten the levers to bring the pedals below the steering column. This means that the pedal stroke is shorter and the pressure higher, but we do not think this matters on the first chassis and it is of vital importance to have ample room for the feet so that there is no danger of interference. The pedal levers shown are similar to the 20/25 but shortened and provided with a split boss so that the proper Bensport pedal plates and stems can be fitted. The footboard has to be in the position shown so that the pedal lever can clear the clutch casing and this board is about 2" nearer the passenger than the final Bensport design. Owing however to the reduced stroke the pedal plates themselves are only about 1" further back than they should be and in this way we have reproduced the final Bensport positions as closely as we think possible with the existing gearbox and clutch units. Referring now to the hand levers, we find these will have to be bent in about 1 1/2" at the top in each case to leave enough room for the hand between the brake lever and the bodywork and between the gear lever and the brake lever. Dimensions are given for the positions of these levers as also for the pedal mechanism. This arrangement drawing should be used in conjunction with Lec's 3258, 3269, and 3275 dealing with the various features of the engine suspension and radiator support. Lec.3280 shows the position of the crossmember for holding up the tail end of the unit. | ||
