Filter

Element

The ZF transmission

has

a filter element'Iocated opposite the

dipstick.

This

filter must

be

replaced whenever the

fluid

is

changed.

Remove

the

filter

by

loosening

the

screw

on

the

cover using

a 6mm Allen

wrench.

Twist

and

pull out

the

filter and remove

the

element. Place

the

new

filter

onto

the

cover and lock it into place

by

turning

it clockwise. Check

the

O-rings for damage

and

replace if

necessary.

Replacement

filters

can be obtained from your

local

WESTERBEKE

dealer or ZF

dealer.

Removing

the

Fluid

Push a suction

pump

hose

down

through

the

pipe hole (under

the

filter)

to

the

bottom of the housing

and

suck out the

fluid.

Remove

the

oil return line

from

the cooler

and

allow

the

oil

to

drain into a

container,

then reconnect

the

oil return

line.

Wipe

down

the

transmission

and

properly dispose of

the

used

fluid.

Replacing

the

Fluid

Pour

in

new

Dextron

III ATF

fluid

and

check

the

quantity

with

the

dipstick.

Transmission

fluid

quantities

will

vary

with

the

use

of

cool-

ers,

length of

hoses

and·the angle of

the

transmission.

Reinsert the

filter

assembly into

the

housing.

Press

it

in

place

and

tighten

the

Allen

screw.

NOTE:

Some

ZF transmissions

use

a

itT"

handle

in

place

of

a

screw

on

their filter

assemblies.

After

running

the

engine,

shut

down

and

recheck

the

fluid

level.

A

WARNING:

Never

pullout

the

dipstick

while

the

engine

is

running.

Hot

fluid

will

splash

from

the

dipstick

hole.

This

could

cause

severe

burns.

MAINTENANCE

Transmission

maintenance

is

minimal.

Keep

the

exterior

housing

clean,

check the

fluid

level

as

part of

your

regular

routine,

and

change

the

fluid

every 300 operating

hours.

Periodically inspect the transmission

and

the cooler

for

leaks

and

corrosion.

Make

certain the air

vent

is

clear

and

when

checking

the

fluid

level look for

signs

of water

contamination

(fluid

will

appear

as

strawberry

cream).

Lay-up/Winterize

Storage

requires

special

care.

Follow these

procedures:

o Drain water

from

the transmission

oil

cooler

and

replace

with

a proper mixture of antifreeze coolant

NOTE:

This

operation

will

normally occur

when

the

engine

raw

water cooling system

is

properly

winterized.

o

Clean

up

the

transmission

and

touch

up

unpainted

areas

(use

heat resistant paint).

o Fill

the

transmission

with

Dextron

III ATF

fluid

to

prevent internal corrosion (extended storage

only,

twelve

months

or

more).

o

Loosen

attaching hardware

from

the

transmission

output

flange

and

propeller shaft

coupling

flange

before

.

removing

the

boat

from

the

water.

Separate

the

flanges

and

spray

with

lubricant.

o Inspect

the

gear shift

cable,

linkage,

and

attachments.

Look

for

corrosion of

the

end

fittings,

cracks

or

cuts

in

the

conduit,

and

bending of

the

actuator

rods.

Lubricate

all

moving

parts.

NOTE:

If

the

transmission

is

to

be

storedfor a

long

time

(twelve

l1wnths

or

more),

it slwuld

be

topped offwith

fluid

to

prevent internal

corrosion.

Reduce

the

fluid level

before

putting

the

engine back

into

service.
