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
generator. Refer to the instructions below when installing
the exhaust elbow purchased for your generator.
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 miXiure 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 aJign-
ment with the exhaust piping is acquired.
5. Carefully tighten the clamp between 2 to 3 Ib-ft, or 24
to
35
Ib-in, or
0.27
to
0.41
kg-m.
CAUTION
Approach the :3 II>-It torque limit with caution.
The clamp's threads will break
if
more than 3 lI>-
ft is applied to Ihe
clamp.
If
a
leak exists, correct it immediately.
