Commencing car numbers:
NOTE.-It
is most important that the Hydrolastic
suspension system be pressurized to the figures given in
'GENERAL DATA'.
During the initial assembly,
or
subsequently
if
a new
displacer unit is fitted, the system should be pressurized
for a period
of30
minutes
to
350 Ib./sq. in. (24,6 kg./cm.
2
)
on
early models,
and
to 400 lb./sq. in. (28,1 kg./cm.
2
)
on
later models (see chart for commencing
car
numbers).
On
all later cars, modified displacer units, helper
springs
and
rear suspension struts are fitted. These com-
ponents are not· interchangeable individually with those
• fitted to earlier cars. The suspension pressure is also
increased to suit the modified units (see 'GENERAL
DATA').
