The fifth speed in the box is an overdrive. A back-axle ratio of 8.25 to 1 is standard. With 10-stud fixing, the wheels carry 36-in. by 8-in. tyres. with, of course, twins at the rear.
The Lockheed brake master cylinder has a 2-in, outlet as against one of 11 ins, diameter in the case of the 7-8-ton chassis, and (lining shoes operate on all six wheels. Hand-brake action is compensated.
A frame of deep section is used, the rear cross-member being suitably reinforced. The .unladen weight of this new chassis, with cab, is 4 tons 15 cwt., and with platform body, 5 tons 7 cwt. Overall length is 20 ft., overall height 7 ft. 91 ins., and width 7 ft. 5 ins. Platform height, laden, is 3 ft. 9 ins.
