GEARBOX. (1). This cannot be done with Oldsmobile type clutch casing to PD.192. (2). Yes, we can provide this. There is not an entirely suitable cover amongst those already used, but the one to close the aperture for the selector rod screws can be used if preferred to an additional cover. (3). This can be done. Whatever is added to the shaft must be accommodated by additional curving of the actuating lever. (4). Reduce locally to give enough clearance as cast. (5). Yes. (6). (7). Detailing Section. (8). Bracket is deleted by new scheme. (9). Detailing Section. (10). Da.{Bernard Day - Chassis Design} investigating. (11). Attachment by screws automatically deals with this point. (12). Can be shortened. (13). Detailing Section. (14). Does not arise with proposed new scheme. (15). Does not arise with proposed new scheme. (16). By disconnecting the rear mounting of the unit it may be possible to swing the rear end sufficiently sideways to remove the cam levers and servo discs. We will investigate. Without disconnecting the mounting it is not possible to remove any more than the cam levers owing to the proximity of the frame cross. If the servo discs can be removed the shaft can probably be withdrawn through a hole in the cross. | ||
