To fit
To assemble, reverse the procedure given for
removal, noting the following points.
1 . All sealing rings and flared pipes must be
thoroughly clean and free from scale. If necessary,
lightly dress with fine emery cloth.
2. To ensure free movement of the joints for
correct alignment of the components when being
assembled, the angular faces of the sealing rings
and grooves in the spherical clamps should be
smeared with a graphite lubricant.
3. Clamp bolt threads should be oiled to
prevent binding.
4.
Do not fully tighten the joints until the
system has been fitted and manoeuvred to obtain
the best run (free from possible fouls) with gc.)od
joint alignment.
5 . The resilient metal exhaust mounts must be
set approximately 6,35 mm. (0.250 in.) forward
before tightening the clamp on the high-frequency
damper. This offset i s to allow the thermal
expansion of the system (see Fig.
45).

To renew
The 'Vibrashock' exhaust mounts may be readily
removed and renewed a s a complete, assembly if
necessary.
If it i s necessary to remove and dismantle an
exhaust mount, care must be taken on assembly to
ensure that the mount cushions are in the correct
position.
The two cushions in the mount vary in rate and
they are colour coded, red and blue, for identifi-
cation. On all the mounts, the blue coloured
cushion, which i s the harder of the two, must
always be fitted uppermost.
The mounts have location tabs incorporated on
the stirrups to locate the 'handcuff' clamps. Care
should be taken when changing mounts to ensure
that the tab i s located correctly.
It i s important when fitting the mounts that the
one with the white colour code i s fitted to the high
frequency damper; the other mounts are coloured
coded yellow. The mount colour coded white bas a
load carrying capacity of 6,8 kg.
(15
lb.); the
yellow coded mount a capacity of 9,07 kg.
(20 lb.).

for torque tightening figures.
Note
When the exhaust system i s fitted, a check should
.be made to s e e that the correct clearances have
been obtained.
