On left-hand drive cars the supply and return hoses
connecting the steering pump to the steering box, drop
vertically from the steering pump to the steering box.
They are secured to each other by
a
plastic clip
mid-way along their length.
With the engine running and the road wheels on
the ground, turn the steering from lock-to-lock and
check that the hoses do not distort.

FIG. N7 STEERING BOX HOSE CONNECTIONS
Steering pump hoses
On right-hand drive cars, the supply and return hoses
connecting the steering pump to the steering box,
drop vertically from the pump to a clip on the upper
triangle lever mounting bracket; from there they pass
across the front engine cross-member, being clipped
to it at two points.
A
shield is fitted to protect the
hoses from heat given off by the exhaust pipe. From
the front engine cross-member the hoses pass to the
steering box
(see
Fig.
N7).

STEERING PUMP-BELT TENSION CHECK
Steering pump fluid level-To check
1.
Start the engine and run it at idle-speed and if
necessary top-up with the approved fluid (see Chapter
D),
until the fluid level is just above the lowest point
of the top face of the filter.
2.
Road test the car.
0
3.
Re-check fluld level.
Note
It is of the utmost importance that only
clean fluid be used to top-up the steering
pump reservoir.
Filter element-To renew
1.
Using a syringe, draw off and discard as much
fluid as possible from the pump.
2.
Unscrew the setscrew securing the cover then
remove the cover and spring; discard the filter
elemcnt.
Fit the new element in the pump reservoir.
3.
Examine the seal
in
the cover; renew if necessary.
Care should be taken to ensure that the oil sealing
ring is seating correctly.
4.
Fit the cover squarely on to the pump and
tighten the setscrew.
Q
Belt tension-To check
The steering and refrigeration pumps are driven
by
a
matched pair of belts from the two front grooves of
the engine pulley.
1.
Check the tension of the belts by applying a force
of
8
lb.
(3,63
kg.) at the centre of the run between the
coolant pump and steering pump. Each belt should
show a deflection of
0.375
in.
(933
mm.).
2.
If
the tension of the two belts differs markedly,
a
new matched pair of belts should be fitted.
3.
To adjust the belts slacken the pump securing
nuts and move the pump until the correct belt tension
is obtained; tighten the nuts.
A
slipping belt will emit a 'squeal' and produces
also 'judder' at the steering wheel, especially when
approaching each full lock.
No dressing of any kind should be applied to the
0
belts to prevent slip.
