Australia is a big place and needs big trucks. This Kenworth C510 pulls a road train with five trailers for the Burton Downs Mine. The poster of the video on YouTube said it’s powered by a Cummins’ 19-litre QSK-19 engine. They add, “The engine delivers 606 hp (447 kW) at 2100 rpm, with peak torque of 1950 lb ft (2644 Nm) at 1300 rpm. Other key components include an 18-speed Fuller RTLO-22918B transmission, with a first gear ratio of 14.4:1 through to 0.73:1 in overdrive. Rear axles are Axle Tech STRC-1297 hub reduction (they’re the old Rockwell off-road model) with a final ratio of 9.59:1. The front axle is Rockwell FL941 rated at 9.1 tonne and the 295 mm deep chassis which has a far thicker web and flange than its highway cousins and features a full length double frame.”
