Exhaust Elbow Installation
The Westerbeke Corporation offers a 45°and 90
0
exhaust
elbow as well as an exhaust riser you can install on your
propulsion engine. Refer
to
the instructions below when
installing the exhaust elbow purchased for your engine.
1.
Coat only one side
of
the exhaust gasket with
'''High
Tack" adhesive sealant. Place this coated surface
against the exhaust manifold's exhaust port flange (the
gasket should stick
to
the flange without falling off).
2.
Place the clamp over the elbow's flange. Place your ex-
haust elbow against the exhaust manifold's flange so
the exhaust manifold's flange rests snug against the
ex-
haust elbow's flange with the gasket centered between
the two.
Now
slip the exhaust clamp over both flanges.
3.
A.
Tighten the clamp just enough so the exhaust elbow
can remain attached
to
the manifold and still be
rotated.
B.
The exhaust elbow discharge must be directed
downward
so the mixture
of
sea water and exhaust
gases will
flow/fall downward into the exhaust muf-
fler which must be positioned below the exhaust
elbow. There should be no loops
or
rises
in
the ex-
haust hose connected between the exhaust elbow
and the
muffler, as these would trap water and pos-
sibly allow water
to
flow back into the engine during
starting
or
at shut down.
4.
Adjust the elbow
by
rotating it until the desired align-
ment with the exhaust piping is acquired.
5. Carefully tighlen the clamp between 2
to
3 Ib-I!,
or
24
to
35 Ib-in,
or
0.2710
0.41 kg-m.
CAUTION
Approach the :I Ib-f!
torque
limit
with
caution.
The
clamp's
threads
will
break
if
more
than
:I
Ib-
tI is applied
to
lhe
clamp.
6.
When the engine is started for the first time with the new
elbow, check Ihis exhaust manifold/elbow connection
for
leaks. II a leak exists, correct it immediately.
