Notes

on

fuel

system

See

on

prior

page

a

typical

exploded

view

of

a

fuel

system

for

this

engine.

It

is

also

illustrative

of

the

self-bleeding

and

priming

system

used

by

Westerbeke.

The

Westerbeke

self-bleeding

fuel

system

is

semi-automatic

in

operation.

While

it

is

unlikely

that

the

operator

will

be

forced

to

service

the

system

at

sea,

the

possibility

does

exist.

Therefore,

it

is

recommended

that

banjo

washers,

injector

seat

washers,

lift

pump

filter

and

gasket,

fuel

filter

and

gasket

be

carried

on

board

at

all

timnes.

Select

the

parts

for

your

engine

on

page

43

and

purchase

spares

from

your

local

Westerbeke

Dealer

or

Distributor.

For

example,

hardware

kit

*34441

will

supply

fuel

system

washers

for

the

Model

46.

If

a

leak

should

develop

at

a

banjo

or

washer

that

cannot

be

remedied

by

a

simple

tightening

of

the

screw,

renew

the

washers.

The

engine

can

be

started

by

taking

steps

described

on

pages

9

and

10.

In

cases

where

the

engine

cannot

be

started

easily,

loosen

two

injection

nuts

on

the

nozzle

side,

turn

the

speed

control

lever

to

"full

open"

position,

turn

the

starter

motor

and

then

tighten

the

nuts

firmly.

4.

Replacing

filter

elements

After

the

first

50

hours

of

operation,

unscrew

and

discard

fuel

filter

element.

Install

a new

filter.

This

same

treatment

is

required

of

the

filter

element

in

the

fuel

lift

pump.

Similarly,

replace

with

a new

filter

element

using

a

new

gasket.

After

the

first

50

hours

change,

the

change

period

may

be

increased

at

200

hours

or

once

per

season.

5.

Fuel

injection

pump

The

fuel

injection

pump

is

one

of

the

most

important

components

of

the

diesel

engine

and

thus

it

calls

for

the

utmost

caution

in

handling.

Furthermore,

the

fuel

injection

pump

has

been

thoroughly

shop-adjusted

and

should

never

be

readjusted

carelessly.

Such

adjustments,

whenever

necessary,

should

be

performed

at

an

authorized

service

station,

as

a

precision

pump

tester

skill

are

required.

To

obtain

long

and

satisfactory

use

of

your

injection

pump:

Always

use

fuel

which

is

free

from

impurities.

Clean

and

renew

the

fuel

filters

periodically.

Inspect

water

entrapment

filter

regularly.
