INTRODUCTION

This

manual

describes

the

operation,

adjustment

and

maintenance

the

Westerbeke

Model

Four-60

Marine

Diesel

Engine,

and

designed

guide

for

those

concerned

with

the

operation

and

maintenance

these

diesels.

The

diesel

engine

closely

resembles

the

gasoline

engine

inasmuch

the

mecha-

nism

essentially

the

same.

Its

cylinders

are

arranged

above

its

closed

crank-

case,

its

crankshaft

one

the

same

general

type

that

gasoline

engine;

has

the

same

sort

valves,

camshaft,

pistons,

connecting

rods

and

lubricating

system

and

reverse

and

reduction

gear.

Therefore,

follows

great

extent

that

diesel

engine

requires

the

same

preventive

maintenance

that

which

any

intelligent

and

careful

operator

would

give

gasoline

engine.

The

most

important

factors

are

proper

maintenance

the

fuel,

lubricating

and

cooling

systems.

Replacement

fuel

and

lubricating

filter

elements

the

time

periods

specified

must

and

frequent

checking

for

contamination

(i.

e.,

water,

sediment,

etc.)

the

fuel

system

also

essential.

Another

important

factor

the

use

the

same

brand

"High

Detergent"

diesel

lubricating

oil

designed

specifically

for

diesel

engines.

The

diesel

engine

does

differ

from

the

gasoline

engine,

however,

the

method

handling

and

firing

its

fuel.

Carburetor

and

ignition

systems

are

done

away

with

and

their

place

single

component

the

Fuel

Injection

Pump

which

per-

forms

the

functions

both.

Unremitting

care

and

attention

the

factory

have

resulted

engine

capable

many

thousands

hours

service.

What

the

manufacturer

cannot

control

how-

ever,

the

treatment

the

product

will

receive

service.

This

part

rests

with

you.

Whenever

service

parts

are

ordered,

always

give

complete

description

and
