 1934 Morris Ten Six - Overview

Last season proved that the roomy willing Morris " Ten " was a firm favourite with the motoring public, and in response to very definite indications we are introducing this season a new and entirely attractive Ten Six. Also the looks and the performance of the original Ten have been graded up for 1934. Definitely these " Tens " are cars that will impress on sight and will be found equally convincing in action.


The new frame with generous X shaped reinforcement a frame within a frame combines lower body lines with increased road holding stability. A new 4 speed synchronised gearbox adds a fine ease to driving-you simply cannot " crash " a change. And any trace of vibration, even at full throttle, is damped out by the exclusive equipoise mounting ' another new Morris feature which completely insulates the engine from the frame,

The new Ten Six has a lively six cylinder side valve power unit based on well tried design. With its quite remarkable performance this model is unquestionably the most inexpensive practical " six " now on the market.


General
The design consists of a six cylinder water cooled engine built in unit construction with a single plate clutch with cork inserts, and a four speed gearbox with synchromesh mech- anism for top and third gears. This power unit is mounted in a deep sectioned downswept frame with generous " X " stiffening member by a resilient equipoise mounting which reduces engine vibrations. The chassis is supported front and rear on long semi-elliptic springs effectively controlled by hydraulic shock absorbers. The track is 4 ft. 0 in. and the wheelbase 8 ft. 6 in.

Engine
The six cylinder engine has a bore of 57 mm, a stroke of 90 mm. and a cubic capacity of 1378 cc, Treasury rating 12 h.p. Tax £ 1 2. The cylinders are cast in one with the skirt of the crankcase which is extended well below the crankshaft centre and liberally reinforced with internal webs, producing a deep girder structure of great rigidity. The crankshaft possesses four bearing soft generous dimensions and is carefully balanced to fine limits. The main and big end bearings are of white metal and of the full ring shimless type. Steel connecting rods of "I" section, individually balanced, are fitted, and the complete assemblies of connecting rods and pistons are equalised in weight to .2 oz. (best aero engine practice). The aluminium pistons possess four rings.

The side by side valves are actuated by adjustable tappets operated from a camshaft of large diameter which is driven from the crankshaft by a duplex roller chain. The combustion spaces are fully machined to ensure equality of compression and the minimum of carbon deposit. The cylinder head is detachable to facilitate decarbonising. The tappet guides are formed in three units which can be completely removed without disturbing any other component. The induction and exhaust manifolds are cast integral and provided with adequate hot spots. An important feature of the induction system is the combined air cleaning and preheating cover which also collects and consumes all fumes discharged from the crankcase breather.

Synchromesh Gearbox
The easy change gearbox is provided with synchromesh mechanism for top and third gears, which are, in addition, of the constant mesh silent type. The gearbox is provided with an accessible filling orifice and a dipstick level indicator.

Lubrication
Oil is circulated under pressure by a spur gear type pump mounted externally on the side of the crankcase, and driven from the camshaft by a diagonal drive shaft and helical gears. The pump feeds the oil by suitable external and internal ducts to each of the main and big-end bearings, and to the camshaft bearings and clutch. The oil is thoroughly filtered before recirculation by a tray type filter of large size covering the whole area of the sump.

Cooling System
The cooling water circulates by thermo-syphon action. It passes from the cylinder head through three well positioned ports of large dimensions which ensure even temperature distribution and the absence of water pockets. The radiator is fan assisted.

Electrical Equipment
The distributor for coil and battery ignition is provided with automatic advance and retard. The distributor is driven from the upper end of oil pump drive shaft which is extended for the purpose. The dynamo is mounted on a cradle on the off-side of the engine and belt driven from the crankshaft. It cuts in at low road speeds. The starter motor is of the sliding pinion type. Full five lamp equipment, including headlamp with dip and switch mechanism, sidelamps, tail-light with stop lamp, is fitted. All switches are accessibly mounted on the instrument panel, with the exception of the headlight dipping switch and horn push, which are conveniently mounted in the centre of the steering wheel, and the battery master switch which is close to the driver's seat. An easily controlled electric windscreen wiper ensures a clear vision during bad weather, and concealed type traffic indicators are fitted.

Carburation
A carburetter of the S.U. automatic piston type with control over mixture strength is fitted. The contro is situated in a convenient position on the facia board, together with the slow running control.

Petrol Tank
The petrol tank is carried at the rear of the chassis and has a capacity of 6A gallons (29a' litres). Its contents are indicated to the driver by an electrically operated dial gauge on the instrument panel. The petrol is fed to the engine by an S.U. automatic Petrolift.

Transmission
The clutch is of the single plate cork insert type running in oil, and is automatically fed with oil from the engine. It is exceptically smooth in action and requires the minimum of attention. A large diameter balanced tubular propeller shaft transmits the power to the rear axle. and is fitted with fabric disc universal joints with centring steadies. The final drive is through silent spiral bevel gears and differential carried in a pressed-steel axle casing. The axle shafts are of the three-quarter floating type.

The Four Wheel Brakes
Lockheed hydraulic internal expanding brakes are fitted to all four wheels. They are fully compensated, smooth, light and certain in action, and maintain their efficiency under all conditions as they have no bearings to wear or need lubrication. The hand brake operates on the rear wheels by independent mechanism.

Steering
The steering gear is of the Bishop cam type, which provides extremely light and safe operation with accurate con- trollability and immunity from the transmission of road shocks to the steering wheel.

Tool Kit
A kit of tools is provided with every car and accessibly housed in a toolbox in the scuttle under the bonnet.
