 1933 Morris Cowley Four - Overview

There can hardly be anyone with the slightest knowlegde of motoring who does not know the Morris Cowley and the reputation for reliability that it has earned. In fact it was the Cowley, probably more than any other which showed motoring publics what "utmost value for money" was obtainle in British cars.

Last year's Cowley was received everywhere as a remarkable improvement in looks, in style all round performance. In an endeavour to improve the excellent, we have this year concentrated upon the engine, modifying it in certain important respects to improve power output and smoothness. The result is that higher speeds are now well within the capabilities of the 1933 model, and this, plus the standardising of the new four speed gearbox, makes the car one of the finest four cylinder models it is possible to buy.


General
Constructionally, the Morris Cowley consists of a four cylinder water cooled engine built in unit construction with a multi plate clutch and four speed twin top gearbox. The power unit is mounted by four point attachments to a sturdy deep sectioned downswept frame of sound design, supported front and rear on long semi elliptic springs, controlled by progressive shock absorbers of the Armstrong hydraulic type. The frame provides a particular low center of gravity and a high degree of road stability. The track is 4 ft (1.219 m.) and the wheelbase 8 ft 9in (2.667 m.).

Engine
The Morris Cowley engine pocesses a bore of 75 mm (2.95 in.) and a stroke of 102 mm (4.01 in.), giving a cubic capacity of 1802 cc (109.97 cu.in.) The four cylinders are cast en bloc with the upper half of the crankxase, which carries the three crankshaft bearings, thus ensureing perfect alignment and rigidity. The inlet and exhaust valves are arranged on the near side of the unit and are operated by adjustable tappets actuated by a chain driven camshaft of large diameter. The valve gearsis completely enclosed by a readily detachable oil tight cover. Decarbonisation is rendered exceptionally easy by the readily detachable cylinder head of special formation. Duralumin connecting rods of "I" section with white meatal bearing carried in generous bronze shells are fitted, as are aluminium pistons. All the crankskaft main bearings are of white metal in heavy bronze shells and provision is made for taking up bearing wear. The clutch is of multi plate type with cork inserts in light steel driven plates. It is automatically lubricated from the engine.

Carburation
The mixture is supplied by a highly efficent automatic S.U. piston type carburetter with top feed float chamber, feeding the cylinders through ports cast intergral with the cylinder block and drawing its air supply throught a large capacity air cleaner and preheater which also collects and consumes all crankcase fume. Adjustment for the mixture strength and slow running is provided by controls on the instrument panel, enabling maximum economy in fuel to be achieved and assuring ease of starting.

Lubrication
Lubrication is by a plunger type pump submerged in the oil sump and driven from an additional four throw cam on the camshaft. It is entirely automatic in its action and also functions as a camshaft vibration damper. The pump intake is surrounded by a readily detachable wire gauze filter and an oil gauge on the dash provides indication of the correct functioning of the lubrication system. The big end bearing and cylinder walls are adequately lubricated from a dipper trough designed to maintain a correct oil level under all conditions. Chassis lubrication is by an Enots high pressure oil gun and accessible niplles.

Electrical Equipment
Ignition is provided by a Lucas coil mounted transversely at the forward end of the engine. The distributor is driven by a diagonal shaft from the camshaft and is placed in a particluar accessible position. Advance and retard of the timming is controlled by a lever conveniently situated in the center of the steering wheel. The lighting and starter motor is of the 12 volt Lucas type, employing a combined dynamo and starter motor (dynamotor). The dynamotor is mounted on the clutch housing along side the gearbox and coupled direct to the power unit by a silent chain which is totally enclosed, adequately lubricated and privided with a simple means of adjustment. Five Lucas lamps are provided, all of which are controlled by a sngle switch on the dash panel and an ammeter on the dash gies clear indication of the dynamotor output and battery discharge. The head lamps are provided with dipping and swiveling mechanism, operated from the sterring wheel and stop light is provided. The entire elctrical equipment os of the Lucas manufacture and includes easily controlled electric windscreen wiper.

Petrol Tank
A 7½ gallon (34 litre) petrol tank is carried at the rear of the chassis. It has a quick action filler cap and carries an electrical gauge giving indication of its contents on a dial mounted on the intrument panel. An S.U. automatic Petrolift provides a gravity feed to the carburetter.

Gearbox
The gearbox has four forward speeds and a reverse, with direct drive on top and silent third speed. It is in unit construction with the engine. The gears are controlled by a cntrally disposed lever and are of case hardened nickled chrome steel the constant mesh and third speed gears being of the double helical pattern to ensure silence. Gear changing is outstandingly easy.

Brakes
The foot brake operates internal expanding shoes in 10 in. (254 mm.) reinforced pressed steel drums mounted on all four wheels by the Lockheed hydraulic system. The brakes are fully compensated and maintain their efficency at all times, since lost motion or loss of leverage, due to wear, is entirely eliminated. The hand brake is of the manual type and operates shoes in the rear brake drum. The brakes are silent in operation and the foot brake automatically operates the stop light when applied.

Wings
The front wings on the Morris Cowley are of the domed type and posscess sideshields which effectively reduces mud splashes on the bodywork

Steering
The steering gear is of the Bishop cam type providing lightness of operation, a high degree of accerate and absence of the road shocks.

Wheels and Tyres
Detachable Magna type wire wheels, equiped with Dunlop cord tyres, are standard equipment

Tool Kit
The following kit of tools is provided with every car and housed in an accessible position on the dash :- Jack (with universal handle, enabling it to be operated in any position and to be withdrawn easily after use), tyre pump, wheel brace, three tubular box spanners and tomrny, three double ended spanners, 9 in. Adjusting spanner, 6 in. aeel punch, screwdriver, diaributor spanner, dynarnotor adjusting spanner, lubricating pump for chassis oiling system, pair of pliers, hammer, sparking plug box spanner, cylinder head box spanner, three tappet spanners, tyre lever and oil can.
