TRANSMISSIONS

SHIPMENT

Por safety reasons, the transmission

is

not

filled

with

transmission

fluid

during shipment

and

the selector lever

is

temporarily attached

to

the actuating

shaft.

Before leaving the WESTERBEKE plant,

each

transmission

undergoes a test

run,

with Dextron III ATF transmission

fluid.

The residual

fluid

remaining

in

the transmission after

draining

acts

as

a preservative and provides protection

against corrosion for at least one year if properly stored.

The oil

cooler,

mounted above the transmission, provides

continuous cooling

for

the transmission

fluid.

Raw

water

passes through the tubes of the cooler

and

discharges

overboard. The transmission

fluid

is

cooled

as

it

flows

around

the tubes and back into the transmission.

TRANSMISSION

FLUID

Pill the transmission with

De),:tron

III

ATF.

The

fluid

level

should be

up

to

the mark

on

the dipstick. After checking the

level, press the dipstick into the case

and

tum it

to

tighten.

During

the

first

25

operating hours, inspect

the

bell housing,

output shaft

and

transmission cooler

for

leakage.

The

fluid

should be changed after the

first

25

hours

and

every 300

hours thereafter.

NEUTRAL

SWITCH

These transmissions

are

equipped with a neutral safety

switch. This

is

to

prevent the engine

from

starting

in

gear.

Unless the transmission selector lever

is

perfectly aligned in

neutral, the engine starter

will

not activate.

INITIAL

OPERATION

Set the shifting lever

to

neutral position

(N).

Start the engine

and

let it run long enough

in

idle

to

fill

the

cooler

and

hoses

with

transmission

fluid.

Shift into

gear,

forward

and

reverse;

shifting should be smooth

and

positive. Direct

changes

from

forward

to

reverse

are

permissible since the multiple

disc

clutch permits changing at high

rpm

including

sudden

reversing at high speeds

in

the event of

danger.

After initial operation,

make

a visual inspection of

the

output

coupling,

oil

cooler

and

hoses,

and the cable connections

to

the transmission.

LOCKING

THE

PROPELLER

Locking of

the

propeller shaft

by

an

additional brake

is

not

required: use

the

gear shift lever position opposite your

direction of travel

for

this

purpose. Never put

the

gear shift in

the position corresponding

to

the direction of

travel

of

the

boat.

WHEN.

UNDER

SAIL

OR

BEING

TOWED

Rotation of

the

propeller without a load,

such

as

when

the

boat

is

being sailed, being towed or anchored

in

a

river,

as

well

as

operation of the engine with

the

propeller stopped

(for charging the battery),

will

have

no

detrimental effects

on

the transmission.

NOTE:

VVhen

the

boat

is

being sailed (engine

stopped),

the

gear shift must be

in

the

neutral position.

The

propeller

is

at

idle and

can

free-wheel.

DAILY

OPERATION

D Check the transmission

fluid.

D

Visually

check the gear shift linkage and transmission.

D Start

the

engine in neutral, allowing a

few

minutes

at

idle

to

warm

the

fluid.

D Shift into

gear.

NOTE:

Too

low

an idle speed will produce a chattering noise

from

the

transmission gear and damper

plate.

In

such cases

the

idle speed should be

increased.

Operating

Temperature

The operating temperature of the transmission should not

exceed

176°P

(80°C).

A connection for a temperature probe

is

provided.

At

maximum output of

the

engine,

the

fluid

may

reach 220

0

P

(104°C).

A

CAUTION:

If

the

transmission

fluid

temperature

is

too

high,

stop

the

engine

immediately

and

check

the

transmission

fluid.
