• Seddon Atkinson has followed in the footsteps of ERF and Foden by specifying the 8.3-litre charge-cooled Cummins C Series engine.
The six-cylinder 6CTAA engine (with a peak installed power rating of 191kW (256hp) at 2,400rpm and peak torque of 948Nrn (6991bft at 1,450rpm) is being offered in the 3-11 sixlegger as an alternative to the turbocharged L10 engine which offers greater torque, but is also heavier.
The C-Series-equipped 3-11 will be available in the same wheelbases as the L10equipped model: 4.26m (tipper); 5.02m (tipper/haulage); and 5.86m (haulage). The average weight saving is 320kg: the only other major difference is that the C-Series-powered 3-11 has an Eaton 6109 nine-speed synchro box, while the LIO chassis keeps the Spicer 10speed splitter. Both, however, have the Eaton double-drive rear bogie. Now Seddon Atkinson is expected to use the C Series engine in its two-axle 3-11 tractor, giving it a lightweight 32tonner to compete against the likes of the Foden 3000 and ERF E8 tractors, which both use the lightweight engine.
The first C Series-engined 311 chassis have alrady gone down the assembly line at Seddon Atkinson's Oldham plant.
