5 ton ( 5 000 kg or 10 000 lb ) payload land or water

For such a large beast the Stalwart is a formidable cross-country vehicle. Approach and depart angles are good, maximum speed on land is claimed to be 40mph, and trenches up to five feet wide can be tackled with impunity. Before taking to the water the operator must undertake a veritable plethora of tasks, chores, and checks! Manoeuverability in water is good, steering being achieved by a combination of vectored thrust from the PTO driven twin Dowty water-jet propulsion units, and the road wheels. Speed through water is said to be about 6 knots.

The “chassis” is, in fact, the hull, and is made from steel, of frameless construction. Suspension is independent all round, utilising torsion bars with parallel links. There are a total of 22 telescopic hydraulic dampers. The engine is mounted at the rear, under the load deck.Drive is taken forward through a 12 inch Borg and Beck clutch, to the 5-speed primary gearbox, which incorporates PTO’s for winch and marine drive. Forward again to the transfer box, which incorporates the reverse and a “No-Spin” diff, the purpose of which is to limit the slippage between left and right wheel sets. This diff can be locked, to fix all six wheels as one solid unit. From here drive is taken out sideways to the centre wheel bevel boxes, then on to the front and rear wheel pairs by further side mounted prop-shafts. Axle half shafts fitted with Tracta CV joints at each end join bevel boxes to wheel hub reduction gears.
