ENGINE

The lubrication of the engine is controlled by the submerged gear type pump together with a full flow oil filter fitted direct to the cylinder block. It is imperative that the correct grades of oil are used, and those recommended are as follows : Temperature Range       SAE Viscosity No.
Summer or Winter            20 or 20W
From 32'F to - 10°F        10W
Below - 10°F                   10W + 10% Kerosene or 5W if                                          available

Checking Engine Oil Level

It is advisable each day to check the oil content in the engine, particularly before the commencement of a long journey. The engine consumes more oil when run at sustained high speeds, and the level must be watched carefully when the car is operated in such conditions. 
To determine the oil level, ensure that the car is standing on level ground, open the bonnet and remove the oil level dipstick which is located on the right hand side of the engine. 
Remove all traces of oil from the dipstick with a clean rag, re-insert the stick into the engine sump and withdraw. The oil level will be indicated by a mark on the lower end of the dipstick. 
The dipstick is calibrated 'FULL' and 'DANGER'. When the oil level reaches the point marked 'FULL', it is at its maximum level. 
Any oil added when the oil level indicates 'FULL' will be wasted and may be injurious to the engine, but, if the level should fall below this mark, further oil will be required. In no circumstances should the oil level be allowed to fall into the 'DANGER' sector indicated on the dipstick. In this condition, any attempt to run the engine will result in serious damage. When replacing the dipstick make sure that it is pushed right into its retaining tube otherwise oil may escape through the gap between the underside of the handle and the end of the tube. 

Draining Engine Oil 

After the first 300 miles (480 km), the engine oil should be drained and thereafter every 5.000 miles (8,000 km) or earlier if excessive fouling has taken place. The oil filter element should also be changed after every 5,000 miles or whenever the sump is replenislied with fresh oil. 
The removal of oil is through the drain plug (1) which is situated beneath the oil filter (2) in the lowest part of the sump. To ensure that the oil flows freely and removes the maximum foreign matter from the surmp, always drain off the engine oil wlen the engine is hot. When the oil has all drained away replace the drain plug securely.

Filling the Sump

The oil filler (3) is mounted on the top of the cadmium plated rocker cover. When adding more oil to the engine, remove the filler cap; the filler cap is of the oil bath air filter type. Do not tilt the cap or oil will be spilled.

Changing the Oil Filter Element

The oil filter (2) is fitted direct to the cylinder block, no connecting pipes to the engine being required. To replace the filter element, remove the hexagon-headed bolt retaining the filter unit to the cylinder block and withdraw the filter assembly. 
Extract the element from the casing and replace with a new element. 
Remove the rubber sealing ring and replace with the new one provided. When replacing the ring, locate the new ring to the groove at four diametrically opposite points. 
Do not fit the ring at one point and then work it round the groove since this may well stretch the rubber and leave a surplus which may cause an oil leak. 
Re-fit the filter assembly to the cylinder block ensuring that the washer is in place under the bolt head.

R2

GEARBOX

The gearbox oil should he drained off after the first 1.000 miles (1.600 km). Thereafter the oil should be changed every 5,000 miles (8.000 km) and the level checked every 1,000 miles. It is preferable to drain off the oil whilst still warm. This condition will assist the oil flow. The combined filler-level plug (4) (located to the lower right of the speedo-meter drive connection) is the re-filling point and care must be taken not to overfill, as this may lead to clutch slip.

R3

REAR AXLE

As with the gearbox. the oil in the rear axle should be changed at the first 1,000 miles (1,600 km) and thereafter at every 5,000 miles (8,000 km). The level should be checked every 1,000 miles (1.600 km). The replenishing of the gearbox with oil is effected via the filter and level plug (5) which is centrally located on the axle case.

R4

UNIVERSAL JOINTS

The propeller shaft universal joints should be lubricated periodically by applying a grease gun containing SAE 120 oil to the nipples (6. 7) protruding on each spider (two nipples).

R5

WHEEL BEARINGS

Every 5,000 miles (8,000 km) the front stub axle wheel bearings (8) should be replenished with a lithium-based bearing grease. Dismantling and access to the bearings is discribed in the 'Front Hubs' section.

R6

FRONT SUSPENSION ARM PIVOT-PINS

  It is important that the grease nipples (four nipples) situated at each end of the radius suspension arm pivot-pins be given five grease gun strokes every 500 miles (800 km).

R7

FRONT AXLE KING PINS

Every 2,000 miles (3,200 km.) a grease gun should be applied to the front axle king pins (10) (four nipples).

R8

STEERING BOX, IDLER AND TRACK RODS

Lubrication of the steering is via grease nipples at the following points.

Steering Box (11) (two nipples). 
Steering Idler bearing (12) (one nipple)----located beneath the fan motor.);
Track Rods (13) (four nipples).

It is recommended that these points be lubricated every 2.000 miles (3,200 km) using a grease gun.

R9

HANDBRAKE

The greasing nipple located on the handbrake cable (14) should receive grease gun attention every 4.000 miles (6,400 km).

R10

GENERAL LUBRICATION

Periodically,a few drops of oil should be applied to the throttle linkage, heater control cables, choke cables, door hinges etc.

Details of the correct lubricants are to be found on the identification plate fitted to the car bulkhead or table (Fig. R.2).
