DESCRIPTION
General
The Volvo 121/122 S is a twoor four-door, five-seater car. Many colours are available and in each particular case the colour of the internal fittings and upholstery harmonizes with the external finish of the car. In addition to a spacious luggage compartment, where the spare wheel and tool kit are stowed, there is also plenty of storage space inside the car itself, such as a shelf with its own lighting under the dashboard, a recessed hat shelf below the rear window and roomy pockets on the inside of the front doors. Standard equipment on the car includes a trip meter in the speedometer, a windscreen washer and a back-up light which goes on automatically when the reverse gear is engaged. Both front seats are fitted with safety belts. The car is of the integral construction type so that there is no separate frame. The front and rear suspensions as well as the engine and transmission are attached directly to the body. The surface finish of the body is synthetic and the primer used rustproofs the body. The car is also thief-proof since the connection between the ignition switch and the ignition coil is in the form of an armoured cable.

DESCRIPTION
The engine is a four-cylinder carburettor unit with overhead valves. The pistons are made of light-alloy and the upper compression ring on each piston is chromed. The main bearings and connecting rod bearings are replaceable. The crankshaft is statically and dynamically balanced.
Engine type B 18 A has an output of 85 h.p. (SAE) and is equipped with Zenith-Stromberg horizontal carburettor. and is equipped Engine type B 18 D has an output of 100 h.p. ( SAE )
with twin SU horizontal carburettors.
Fuel system
The fuel system is fed from the tank to the carburettor by a fuel pump which is driven by a cam on the engine camshaft. There is a filter in the fuel pump which traps water and other impurities in the fuel.
Lubricating system
The engine lubrication is taken care of by a gear pump which sucks up oil from the sump on the bottom of the engine and forces it through the oil filter out to the lubricating points in the engine. A relief valve is built into the oil filter which prevents the oil pressure from reaching excessively high values.
Cooling system
The engine is water-cooled and the cooling system is of the pressure type. Water is circulated by means of a pump fitted on the fan shaft. A thermostat with an opening temperature of about 76 ° C (169 ° F) prevents the cooling water from passing through the radiator before the engine has reached its normal working temperature.

DESCRIPTION
Electrical system |
|
|
The electrical system is of the 12-volt type and is fitted with a volt- |
|
age control dynamo. The starter motor is controlled from the instrument |
|
panel by means of the ignition key. This key also forms the main switch |
|
for the rest of the electrical system. The cables to the headlights, parking |
|
lights and internal lighting, however, are not taken over the ignition |
|
switch but can be switched on and off without the ignition key being in |
|
position. |
Lighting |
|
|
The lighting on the vehicle consists of two headlights (full and dipped) |
|
together with two combined flasher and parking lights. At the rear the |
|
lighting consists of two tail lights including flashers, combined lamps for |
|
the tail lights and brake warning lights, and the back-up light. Internal |
|
lighting consists of a roof light above the rear view mirror and a light |
|
for the parcel shelf. |
Fuses |
See pages 42-44 concerning replacement of bulbs. |
The electrical system is protected by means of fuses fitted in a fusebox to |
|
|
the left on the bulkhead under the bonnet. When replacing a fuse, be sure |
|
that you use a one of the right rating. If one of the fuses should blow |
|
repeatedly, do not fit a more powerful fuse. Instead, take the vehicle to |
|
a workshop for a check of the electrical system. |

DESCRIPTION
Power transmission
Clutch The function of the clutch is to transmit the power from the engine to the gearbox. The clutch is of the single dry plate type with diaphragm spring. The diaphragm spring 'functions partly as a lever when declutching and partly as a pressure spring when engaging.
Gearbox
The gearbox is used to regulate the speed ratio between the engine and the rear axle so that the engine always operates in its most favourable speed range. The gearbox is synchronised on all the forward gears; this means that gear-changing can be carried out without double declutching. Since the gearbox is fitted with helical gears and the gear lever is rubber insulated, excellent sound insulation is obtained. See page 57 for data.
Propeller shaft
The propeller shaft, which is the connecting link between the gearbox and the rear axle, is divided into two sections. The forward section is journalled at its rear end in a bearing housing suspended in a rubberized ring.
Rear axle
The driving power of the engine is transmitted from the propeller shaft to the rear wheels through the rear axle. The rear axle is of the hypoid type, i.e. drive pinion is below the centre line of the drive shafts. See page 57 for data.
Brakes
The vehicle is equipped with disc brakes at the front and drum brakes at the rear as standard. The brake system is also provided with a reducer valve, which prevents involuntary locking of the rear wheels.
The footbrake system is hydraulic and influences all four wheels. The hydraulic system consists of a 'fluid-filled master cylinder which, when the brake pedal is depressed, transmits the brake pressure through the brake fluid in the lines to the wheel unit cylinders. The plungers in these are then pressed outwards and apply the brake shoes or brake pads respectivly.
Vehicles fitted with the B 18 D engine are also provided with vacuum type servo brake cylinders.
The handbrake system operates mechanically on the rear wheels.
Wheels and tyres
14
The vehicle has pressed steel wheels with lugs for the attachment of the hub caps. All wheels are carefully balanced and the tyres are of the tubeless type.

DESCRIPTION
Body
Bonnet
The bonnet is fitted with a catch which is operated from the driving seat through a handle located to the left under the instrument panel. The bonnet catch is released by pulling the handle out.
When the bonnet catch handle has been released inside the car, the bonnet is still retained by a safety catch. After this is pressed in as shown, the bonnet can be lifted up. When the bonnet is closed the bonnet catch is automatically locked and cannot be lifted until the handle inside the car has been pulled again. Check to make sure that the bonnet is properly secured when it is closed.
Luggage compartment
The door key is used to lock the luggage compartment, which is opened by pressing the handle upwards as shown. The luggage compartment lid is balanced and does not need to be held up. To the left in the compartment there is room for the spare wheel and tool kit. Always make sure that the spare wheel is fastened securely and that the tool kit is firmly stowed, otherwise irritating rattles can occur.
16
Doors and locks
There is a lock with a keyhole on each of the front doors. All the doors can be locked from inside the car by pressing down the lock buttons on the window ledge. On the rear doors, this button must first be pulled up before the doors can be opened from the inside. This is an important safety factor if children are alone in the back. All the doors can be locked by pressing down the internal lock button and then closing the doors. Do not leave the keys in the car, otherwise you can easily lock yourself out.
Many people make it a habit of pressing down all the lock buttons. In itself this is not an extra safety precaution. On the other hand, however, the passengers are locked in and this might be dangerous should an accident occur, especially involving fire. For this reason you should always leave at least one door (for example, one or both front doors) "unlocked" when driving.
The doors are opened from the inside by turning the handle to the rear. The ventilation windows for the doors are opened by unscrewing the lock stud, after which it can be pressed in and the handle turned upwards. With the stud in the screwedin position, the handle is locked.
The rear side windows of two-door cars can be partly opened by setting the handle at the rear edge in different positions (does not apply to 13121).
In order to prevent freezing-up of the locks, a suitable anti-freeze agent should be used in cold weather. If the locks are already frozen, do not exert undue force on the key otherwise you might break it. Instead, heat it with a match or similar and place it quickly into the keyhole.
