4. Support the inlet and outlet
pipes with soft wire.
5. Separate the muffler from the
inlet and outlet pipes and remove
the muffler.
6. Replace any damaged parts.
INSTALLATION
1.
Slide the muffler onto the in-
let
pipe,
and position the inlet pipe
to
muffler
inlet
pipe
extension
clamp.
2. Slide the outlet pipe into the
muffler and position the outlet pipe
to muffler clamp.
3. Adjust
the
exhaust
system
components to conform to the clear-
ances
shown in
Fig.
1 to 14 and torque
the retaining clamps to
specifications.
Re-
move temporary support

INLET PIPE
6 CYLINDER ENGINE
REMOVAL
1. Loosen the inlet pipe clamp at
the front end of the muffler inlet
pipe extension and slide the clamp
rearward onto the inlet pipe ex-
tension.
2. Remove the clamp attaching
the inlet pipe to the flywheel/con-
verter housing support bracket.
3. Support the front end of the
muffler inlet pipe extension with
·soft wire.
4. Remove the nuts that secure
the inlet pipe to the exhaust mani-
fold. Separate the· inlet pipe from
the exhaust manifold and muffler
inlet pipe extension and remove the
inlet pipe.
5. Clean the gasket surface of
the exhaust manifold.
6. Discard the gasket and replace
any damaged parts.
INSTALLATION
During reassembly of the 250 2V
exhaust manifold, it is advisable to re-
assemble the manifold to cylinder head
bolts,
starting from the back of the
engine.
This is recommended as misalignment of
the bolt holes due to distortion can
occur with this type of exhaust
manifold.
1. Install a new gasket on the
flared end of the inlet pipe. Slide
the clamp onto the inlet pipe which
attaches the inlet pipe to the fly-
wheel/ converter
housing
support
bracket.
2. Install the ihlet pipe to the
muffler inlet pipe extension and
exhaust manifold. Position the in-
let pipe
flan~.
e
and install the re-
taining nuts on the !ltuds of the
manifold snug, but not tight.
3. Position the inlet pipe to the
muffler inlet pipe extension
clamp.
Position the inlet pipe to the fly-
wheel
;
convertor
housing
support
!:racket clamp. Remove the temp-
orary support
wire.
4. Adjust
the
exhaust
system
components to conform to the clear-
ances shown in
Figs.
1-7. Working from the
front of the car toward the rear,
progressively torque the retaining
nuts and clamps to specifications.
5. Start the engine and check the
exhaust system for leaks.

1.
Install
l'lew gaskets on the
flared ends of the inlet pipe.
2. Install the inlet pipe to the
muffler inlet pipe extension and ex-
haust
manifolds.

ing nuts on the studs of the mani-
fold snug, but not tight.
3. Position the inlet pipe to the
muffler inlet pipe extension
clamp.
Remove the temporary support wire.
4. Adjust
the
exhaust
system
components to conform to the clear-
ances shown in
Figs.
8-14.
Working from
the front of the car toward the
rear,
progressively torque the retain ing
nuts and clamps to specifications.
5. Start the engine and check the
exhaust system for leaks.
