Schrader valve checks on Scammells

• Scammell air-brake systems are to include a series of Schrader-valve points on which a pressure gauge can quickly be put to determine whether a section of the air system is sound or not. There are up to 17 of these check points on a chassis, the exact number depending on the model. A trouble-shooting chart will be available to guide the pressure-check procedure.
All pipes on Scammell chassis are now cadmium plated, with flared ends and an automatic condensate-drainer is standard equipment.
Under the front bumper of new Scammells is a special air-pipe with a quick-release dust cap. This is for connecting to the air supply • of a towing vehicle in an emergency so that the brakes of the towed vehicle always come into action whenever the towing vehicle's brakes are operated. These brake-system changes are additional to improvements to Scammell Handyman and Routeman tractive units that include a radiator header tank and a large-capacity paper-element air filter, mounted behind the cab, double sealing of the doors and rubber skirts that cover the gap between the cab and the chassis. The Routeman eight-wheeler is equipped with a vertical exhaust silencer behind the cab, the flexible joint being of the stainless-steel bellows type.
Air is drawn into the filter through a reinforced plastics casing that has a grilled opening in the side; the form and position of the filter intake are designed to promote aspiration of clean cool air into the engine and to reduce the noise level. The rubber skirts are said to muffle engine noise and shield the engine from road spray and dirt.
