MANAGEMENT OF CAR. DRIVING THE CAR TO START THE ENGINE IMPORTANT-When starting the engine at any time : If the engine does not start when the starter is operated, do not re- operate until both starter motor and engine have come to rest. This is to avoid damage to the starter pinion. Starting when Engine is Cold Place the gear lever in the neutral p[...]

DRIVING THE CAR-The Engine DRIVING Gear Changing For a smooth gear change into a synchronised gear (4th, 3rd & 2nd) the movement should be slow and deliberate. The gear lever must always be moved right home to secure full engagement. First and reverse gears are not synchromesh, gear engagement being achieved by sliding the respective gear into [...]

GENERAL UPKEEP REGULAR INSPECTION Every 250 miles (400 km.) the oil level should be checked when the engine is cold, and topped up if necessary. Withdraw dipstick ((F) Fig. 3) and wipe clean, then insert and push fully home before withdrawing for reading. Should the level be at the lower mark on the dipstick, 4 pints (2.2 litres) of oil will be req[...]

GENERAL UPKEEP-Cooling System and Lubrication COOLING SYSTEM Filling (see page 11). Draining For the purpose of draining, taps are provided in the bottom tank of the radiator and at the rear of the cylinder block on the right-hand side. As the cooling system is pressurised it will be necessary, when draining, to remove the radiator cap (E), Fig. 3.[...]

GENERAL UPKEEP-Lubrication Draining To drain the engine, gearbox and rear axle, remove the plug provided beneath each unit. This process is assisted by opening the filler to allow ingress of air and by draining when the oil is hot, i.e., immediately after a run. ENGINE Only first quality oils are recommended for use in the engine sump. These are ea[...]

GENERAL UPKEEP-Lubrication Carburettors Every 6,000 miles (10,000 km.) unscrew the brass hexagon plug in the top of each of the carbur- ettors and top up with current engine oil to the level of the inner hollow shaft. Apply oil also to the throttle linkages on the engine, do not oil the bear- ings of the transverse rod at- tached to the scuttle as [...]

GENERAL UPKEEP-Lubrication The container should not be disturbed until cartridge renewal is required ; as the accumulated dirt on the outside of the container may fall inside and thus be carried into the bearings when the engine is re-started. Ignition Distributor (see Fig. 5) Every 6,000 miles (10,000 km.), the cam (B) should be smeared lightly wi[...]

GENERAL UPKEEP-Lubrication Dynamo and Starter The dynamo front bearing is packed with grease before leaving the works, and after a considerable mileage the dynamo should be removed for clean- ing, adjustment and repacking of the bearing with grease. This should be done preferably by the nearest Triumph or Lucas Service Depot. Every 12,000 miles (20[...]

GENERAL UPKEEP-Lubrication It is advisable to have the oil level checked during this period, and especially after the first 1,000 miles, and replenish if necessary to level with the bottom of the threads in the filler orifice. Should a top-up be necessary, investigate the cause of oil loss. The filler plug is accessible from underneath the car, bei[...]

GENERAL UPKEEP-Lubrication Handbrake Cable Conduit A grease nipple is fitted in the conduit, as shown in the lubrication chart, to which the grease gun should be applied every 6,000 miles (10,000 km.). During the winter months it is very important to keep the cable regularly lubricated, as this prevents the entry of water which on cold nights will [...]

GENERAL UPKEEP-Lubrication and the steering slave drop arm pivot. Do not lubricate the joints attached to the drop arms as they contain rubber. The inner bushes of the wish-bones on early models also contains rubber. Later models have nylon bushes which should be lubricated with oil occasionally. A pronounced squeak develops should these bushes bec[...]

GENERAL UPKEEP-Lubrication PROPELLER SHAFT The universal joints are of the needle roller bearing type and together with the splines should be lubricated every 6,000 miles (10,000 km.). The nipple (B) at each end of the shaft should be supplied with oil for the bearings and the nipple (A) with grease for the splines. REAR ROAD SPRINGS The spring bla[...]

GENERAL UPKEEP-Tyres TYRES The maintenance of correct tyre pressure is a large factor in tyre life and the steering and suspension of the car. Examine the tyres occasionally for flints or other road matter which may have become embedded in the tread. Clean off any oil which may have got on the tyres by using fuel sparingly. Driving into or over sha[...]

GENERAL UPKEEP-Tyres Changing Position of Tyres It is recommended that front tyres be interchanged with rear tyres at least every 3,000 miles (5,000 km.). Diagonal interchanging between left front and right rear and between right front and left rear provides the most satisfactory first change, because it reverses the direction of rotation and keeps[...]

Dust may be removed from the exterior using a soft cloth only, but if it has been wet at any time it is advisable to use a sponge and water. Always use water when removing mud and when the car is clean finally wipe over with an almost dry chamois leather. Washing alone will not keep up the brilliance of the paintwork ofer an indefinite period and i[...]

BODYWORK Fig. 13. "Tenax" soft top fasteners. It may be found advantageous when removing the fasteners from the screen, to relieve the tension on the fasteners by applying a slight hand pressure, in the forward direction, to the corrier of the soft top where it passes over its supports. SPARE WHEEL AND TOOL STOWAGE The spare wheel is hous[...]

RUNNING ADJUSTMENTS Various adjustments are necessary from time to time in order to keep the mechanism in efficient running order. The periods between depend largely upon the manner in which the car is used and no definite time can be given here for carrying out these corrections. The car should be examined however every 6,000 miles (10,000 km.) an[...]

RUNNING ADJUSTMENTS-Engine A new gasket must be fitted each time the cylinder head is removed. The plain side of the gasket must be downwards against the cylinder block and should be coated on both sides with cc WELLSEAL" or similar non-setting sealing compound. When replacing the cylinder head nuts, tighten them gradually in the sequence show[...]

RUNNING AD JUSTMENTS-Engine Adjustment Remove the roeker cover and turn the engine crank with the aid of the starting handle for half a revolution after the valve to be adjusted has closed. It is easier to do this if the sparking plugs are removed. This also provides an opportunity for inspecting and checking the sparking plug gaps. Slacken the loc[...]

RUNNING AD JUSTMENTS-Engine Sparking Plugs The sparking plugs were adopted for original equipment after lengthy tests and as sparking plug types vary in suitability for different engines, it is important that the correct type of plug be fitted when making replacements, this is : Champion No. LlOS-$" reach. In countries where the octane rating [...]

Adjustment As the needle size is determined during engine development, adjustment of the carburettors is confined to correct idling adjustment. Remove the air cleaners and run the engine until it has attained its normal running temperature slacken one of the clamping bolts (B) on the throttle spindle connection and disconnect the mixture control li[...]

RUNNING AD JUSTMENTS-Engine if the float chamber is not already full, under which condition a slight pumping resistance is felt before the lever reaches its stop. This resistance ceases when the chamber is full. Fig. 18. Fuel pump. The glass bowl acts as a sediment chamber for the petrol passing to the pump. The foreign matter collects on the under[...]

RUNNING ADJUSTMENTS-Clutch CLUTCH A Borg & Beck single dry plate hydraulically operated clutch is fitted and as it is correctly set before leaving the works, it will be some considerable time before it requires re-adjustment. The hydraulic master cylinder for the clutch has a conamon filler with the brake system. (See arrow (B) Fig. 3, page 11.[...]

RUNNING AD JUSTMENTS-Brakes See page 17 for checking level of fluid in reservoir. If it is found to be par- ticularly low, it is an indication that a leak has developed somewhere in the system and it should be traced and rectified without delay. It must be remembered that the presence of oil, grease or sidar foreign matter on a drum brake shoe will[...]

RUNNING AD JUSTMENTS-Brakes The following procedure should be followed to correctly adjust the brakes: 1. Apply the brakes hard, with the car stationary, to position the shoes in the drum, then release brake. 2. Jack up the car, remove the nave plates and road wheels. 3. Rotate hub until hole provided in the brake drum coincides with screwdriver sl[...]

RUNNING ADJUSTMENTS Handbrake Adjustment (both makes) Adjustment of the rear brake shoes as previously described automatically readjusts the handbrake mechanism. The cables are correctly set before leaving the works, and only maladjustment will result from tampering with the mechanism. Bleeding the Brake and Clutch Hydraulic System If a pipe joint [...]

RUNNING ADJUSTMENTS The front telescopic dampers fitted do not require any adjustment or topping up. If the dampers are removed, or for some reason new ones are fitted, it is advisable to hold them the right way up (in the case of the rear dampers check the level of the fluid and replenish if necessary), then pump the pistons to each end of the str[...]

ELECTRICAL SYSTEM A 12 volt earth return (or one wire) lighting and starting set is fitted. One cable should be disconnected from the battery terminal before removing any electrical unit, otherwise there is a risk of a serious " short."
