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 :
SAE Viscosity No.
Summer or Winter
20 or 20W
From 32'F to - 10°F
Below - 10°F
10W + 10% Kerosene or 5W if
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
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
Re-fit the filter assembly to the cylinder block ensuring that the washer
is in place under the bolt head.
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.
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.
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).
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'
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).
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).
STEERING BOX, IDLER AND TRACK RODS
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
Track Rods (13) (four nipples).
It is recommended that these points be lubricated every
2.000 miles (3,200 km) using a grease gun.
The greasing nipple located on the handbrake cable (14)
should receive grease gun attention every 4.000 miles (6,400 km).
Periodically,a few drops of oil should be applied to
the throttle linkage, heater control cables, choke cables, door hinges
Details of the correct lubricants are to be found on
the identification plate fitted to the car bulkhead or table (Fig. R.2).
