EXHAUST SYSTEM
I.
DESCRIPTION
The manifolds are attached to one another
by studs in the aluminium alloy induction
manifold and lugs moulded in the cast
iron exhaust manifold. There is no
"
hot spot
"
for easy starting.
The exhaust system is situated on the
right-hand side of the engine and passes
down to the rear of the car through the
centre of the cruciform to a position
adjacent to the left-hand chassis member.
The front exhaust pipe is attached to the
engine by a flange and is flexibly mounted to
the chassis frame at a point forward of
the cruciform centre. This attachment also
secures the ipe to the outside of the
silencer.
&S
with Commission No.
TS.4310 and before has this clip in two
halves as shown in Fig. 1.
Two types of silencers have been used in
production, the former 18" silencer being
changed for a 2 4 type at Commission
No. TS.2532. A modified tail pipe incor-
porating a 12" silencer can be fitted, at the
owner's discretion, to the shorter type
silencer, if the exhaust note is considered
too loud (see Fig. 2). This modified
tail pipe fits into the main silencer and is
attached with the existing clip.
At the rear the tail pipe is attached to the
chassis by a flexible mounting strip and the
clip secures the chromium plated extension
piece inside the tail pipe.
2.
MAINTENANCE
The exhaust system should be inspected
periodically to ensure its correct function.
Attention should be paid to the gaskets at
the cylinder head, carburettor and front
exhaust pipe flanges to ascertain their
condition. If signs of
"
blowing
"
are
detected then gasket must be replaced as
soon as possible. Manifold gaskets should
be replaced as a pair and no gasket should
ever be used twice.
The flexible mounting strips should be
inspected and replaced if any deterioration
is apparent.
The position of the silencer assembly in
relation to the cruciform centre should
always be such that during any vibrationary
period the exhaust system cannot come
into contact with the cruciform.
