2 (K). ROAD SPRINGS. Both back and front are semi-elliptic and very long for the size of chassis. They are extremely carefully fitted, and at the front end of each spring where the control is taken, they are provided with solid ends having central eyes to avoid road shocks causing unnecessary and dangerous bending stresses. (L). FRAME. The frame is of deep channel section and is fitted with a number of tubular cross members to render it more rigid than usual against twisting, and brackets are provided along the outside for the attachment of the bodywork so making it unnecessary to use wide and heavy runners in body construction, and permitting the rear seats to be unusually low. Every effort has been made to keep the frame low and considering the large road wheels (33") and large road clearance (11") this has been extremely successful. (M). LUBRICATION. Engine - pressure by pump with float & pointer level indicator. Gearbox & back axle - (oil retaining) splash. Road wheels & universal joints - oil retaining. Details (spring shackles) by portable grease injector with rapid connectors. The oil consumption on this chassis is remarkably low (the engine running 1000 miles to the gallon.) This is due to the care given to the oil retaining in the design of the bearings and oil joints about the whole chassis, and to the design of the pistons which are extremely good for not allowing oil to work up into the combustion chambers. (N). PEDALS. The pedals have long strokes to permit of light operation, and avoid frequent adjustments of the operated parts. They are fitted in 2 positions, corresponding to the 2 positions of the (8) | ||
