CARE AND MAINTENANCE.
For correct lubrication of all engine parts, it is only necessary to maintain the
correct oil level in the sump. This
is
ascertained by a Dipstick located on the right
hand side of the engine.
On all new or reconditioned engines, the sump and full flow oil filter should be
drained and refilled with new oil after the first 500, 1,000 and 2,000 miles. After
this the operation should be repeated every 2,000 miles to provide the best running
conditions.
There
is
one drain plug in the sump and one near the bottom of the oil filter
reservoir (See (b) Fig. 3). The capacity of the engine lubrication system is 15 pints
(8.4
litres), plus 2 pints (1.13 litres) for full flow Tecalemit Filter.
Cylinder Head Nuts
After the first 500 and 2,000 miles of running, the cylinder head nuts should be
tightened. Tighten each nut a little at a time, working from the centre outwards.
This operation should be carried out when the engine
is
hot. Tappets must be
checked after this operation and readjusted if necessary.
Oil Pressure.
The oil pressure gauge indicates whether the oiling system is working correctly
and
it
should be looked at occasionally while the engine
is
running.
The normal working pressure
is
55 p.s.i. and the idling pressure
is
26 p.s.i.
Should the normal oil pressure appear low, then
it
is
possible that the full flow Tecal-
emit oil filter
is
choked and in need of renewal. Never run the engine if the oil
gauge does not register pressure as serious damage may result.
Chassis Lubrication.
The various points of the chassis should receive periodical attention as indicated
in the Lubrication Chart on Page 11. It
is
of
vital importance
that the rear hubs
receive attention at the periods recommended, as the rear hub bearings are actually
sealed from the oil circulating in the main casing.
Rear Axle Lubrication.
The standard rear axle for this model is a Hypoid Bevel type with a ratio of
2.93
:
l.
After the first 2,000 miles, drain the rear axle and refill with a recommended
type of new oil to the level of the combined oil filler and level plug. The oil level
should be checked every further 2,000 miles and topped up when necessary.
It is extremely important that only approved Hypoid oils be used with
this axle, without the use
of
additives
of
any kind.
Gearbox Lubrication.
Drain gearbox and refill with new oil to the top level on the dipstick after the
first 2,000 miles. Access to the dipstick and oil filler plug is gained by lifting the
rubber plug in Tunnel. The capacity of the gearbox is 63 pints and if Overdrive
is fitted the combined capacity of Gearbox and Overdrive
is
8
pints, the oil level on
the gearbox dipstick remaining the same. Thz oil level should be checked every
further 2,000 miles and topped up when necessary.
