An article from 'The Engineer', 9th November, 1923:
A newcomer amongst the less expensive cars which impressed us very favourably is the 14 horsepower Bean, made by A. Harper, Sons and Bean, Limited, Dudley. In both design and construction the 14 horsepower chassis is a great advance over the firm’s previous machines, and represents wonderful value, even in these days of keen competition.

The chassis of the 14hp. Bean car.

The engine is of the four-cylinder monobloc pattern, with a detachable head, its chief dimensions being 75mm bore by 135mm stroke, and operated by a three-bearing crankshaft; the valves are interchangeable. The camshaft is operated from the crankshaft by an adjustable silent chain, which also drives a sprocket on the end of the dynamo shaft. A second and smaller sprocket on the latter serves to drive the fan and magneto, a Herner coupling being provided for adjusting the timing of the magneto, while for regulating the tension on this chain the magneto is carried in a cradle secured by studs and slots to permit movement. The induction manifold is integral with the cylinder block and is water-jacketed. The crankshaft is carried on three bearings, and is balanced.

The engine, gearbox, and clutch unit.

The engine is lubricated under pressure by a gear wheel pump, driven by spiral gears from the camshaft. The pump is enclosed in a filter in the sump which forms the lower half of the crankcase and delivers oil through the hollow crankshaft to the main and big end bearings and camshaft, the oil pressure being adjustable by a regulator valve. Superfluous oil from this valve is fed direct to the timing chain and then drains back to the sump.

The timing drive, and the magneto and dynamo.

The Delco-Remy coil ignition system can be fitted in addition, if desired. The gearbox provided four forward road speeds and a reverse, the power being transmitted to the axle by a tubular propeller shaft fitted at either end with a universal joint of the sliding block type. The clutch consists of five steel plates, three of which are covered with Ferodo and run dry. There is an adjustable spring loaded clutch brake fitted to ensure silent gear changing. The final transmission is by spiral gears of substantial dimensions, and the differential is of the bevel type. The rear axle is of the three-quarter floating type, the wheel hubs being carried on large ball journal bearings.

The front view of the chassis, showing the brakes.

The car is fitted with four brakes on the Perrot system, and the view of the front of the car shows that the axle has been specially designed to withstand the stresses imposed by front wheel brakes. The engine is capable of developing over 40 horsepower on the brake.
