Exhaust Elbow Installation

The Westerbeke Corporation offers a

45° and

90°

exhaust elbow as

well

as an exhaust riser

you

can

install

on

your engine. Refer

to

the instructions

below

when installing the exhaust elbow purchased.

NOTE:

Fabricated exhaust elbows or risers attached

to

the exhaust manifold must not exceed 8 Ibs when

unsupported.

L Coat only one side

of

the exhaust gasket with

High Tack adhesive sealant (manufactured

by

Permatex Company, Brooklyn, NY). 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 exhaust elbow against the exhaust manifold's

flange

so

the exhaust manifold's flange rests snug

against the exhaust elbow's flange with the gasket

centered between the

two.

Now

slip the exhaust

clamp over both flanges.

3.

Tighten the clamp just enough

so

the exhaust

elbow

can remain attached

to

the manifold and still

be

rotated.

The exhaust elbow discharge

must

be

directed

downward

so

the mixture of raw water and exhaust

gases will flow/fall downward into the exhaust

mnlller which

must

be positioned below the exhaust

elbow.

There shonld be

no

loops or rises in the

exhaust hose connected between the exhaust elbow

and the mnlller, as these would trap water and

possibly allow water

to

flow back into the engine

during starting or at shut

down.

4.

Adjust the elbow

by

rotating

it

until the desired

alignment with the exhaust piping is acquired.

5.

Carefully tighten the clamp between 8

to

10

Ib-ft,

or

96

to

120

Ib-in., or

LI

to

1.3 kg-m.

II

CAUTION

II

Approach the

10

lb-ft torque limit

with caution. The clamp's threads

will break

if

more than

10

Ib-ft

is

applied

to

the clamp.

If

a leak exists, correct it immediately.
