Cummins E290 for Bedford

THE TOPWEIGHT Bedford TM 3800 is now available with a Cummins engine. Timed to coincide with the launch of the new Formula E290 engine. (see story below) the Bedford announcement has ended speculation that an alternative power unit to the two-stroke Detroit Diesel 8V-71 was on the way.
Because of the low-revving characteristics of the new Cummins, a change of rear axle has been necessary.
The French-built SOMA hub-reduction design gives way to a single-reduction Rockwell, as the SOMA range does not include a high enough ratio. The ten-speed Spicer splitter box is retained, however.
Bedford has not yet built a chassis with the new Cummins — all the installation design • work was done with the 'old' 290 — so no kerb weight figures are as yet, available.
However, the Detroit Diesel, at 1,090kg (2,3951b), is a very light engine, so the Cummins, at 1,160kg (2,560Ib), is going to add a weight penalty.
There are no plans to offer any other engines in any other chassis at the moment.
