TRANSMISSIONS

CABLE

CONNECTIONS

The

transmission

is suitable for a

single

lever gear

shift.

Upon

loosening

the retaining

screw,

the

actuating lever (see

illustration)

can

be moved

to

any

position

required for

the

control

elements

(cable or rod

linkage).

Make

certain that

the

actuating lever

does

not contact

the

lever

hub:

the

minimum

distance

between

the lever

and

the

hub

should be

O.02in

(O.5mm).

The

control

cable or rod should be

arranged

at

a ught

angle

to

the

actuating

lever when

in

the

neutral

position. The

neutral

position

of

the gear shift lever

on

the

control console

should coincide

with

the neutral

position

of

the

lever

on

the

transmission.

The

shifting

travel,

as

measured

at

the

pivot point of the

actuating lever between the neutral position

and

end positions

A and

B,

should

be at least I-3/8in

(35mm)

for

the outer

and

I-3116in

(30mm)

for the inner pivot

point.

N

,ACTUATING

LEVER

A greater

amount

of actuating lever

travel

is

in

no

way

detrimental

and

is recommended.

However,

if

the lever travel

is

shorter,

proper clutch engagement might be impeded

which,

in

tum, would mean premature

wear,

excessive heat

generation

and

clutch plate failure.

This

would

be indicated

by

slow

clutch

engagement or

no

engagement at all (see

CONTROL CABLES under TRANSMISSION

TROUBLESHOOTING)

NOTE:

Checkfor proper actuating lever travel

at

least each

season.

A

CAUTION:

The

position

of

the

mechanism

behind

the

actuating

lever

is

factory-adjusted

to

ensure

equal

shift

lever

travel

from

neutral

position

to

A

and

B.

If

this

mechanism

is

in

any

way

tampered

with,

the

transmission

warranty

will

be

void.

SHAFT

COUPLINGS

WESTERBEKE

recommends

a

flexible

connection

between

the

transmission

and

the

propeller shaft

if

the

engine

is

flexi-

bly

mounted,

in

order

to

compensate

for

angular

deflections.

The installation of a

special

propeller thrust

bearing

is

not

required, since the propeller

thrust

will

be

absorbed

by

the

transmission

bearing,

provided

the

value

specified

under

SPECIFICATIONS

is

not

exceeded.

However,

the

output

shaft

should

be

protected

from

additional

loads.

Special

care

should be

taken

to

prevent

torsional

vibration.

When

using

a

universal joint

shaft,

make

certain

to

observe

the

manufac-

turer's

instructions.

Even

with

the

engine

solidly

mounted

the

use

of a

flexible

coupling or "DRIVESAVER"

will

reduce

stress

in

the

gear-

box

bearings

caused

by

hull

distortions,

especially

in

wooden

boats or

where

the

distance

between

the

transmission

output

coupling

and

stem

gland

is

less

than

about

800mm.

NOTE:

When

installing

the

transmission,

make

certain

that

shifting

is

110t

impeded by restricted movability

of

the

cable

or rod

linkage,

by unsuitably positioned guide

sheaves,

too

small a bending

radius

or other

r€<5trictions.

In

order

to

111OUl2t

a support for shift control cable

connections,

use

the

two

threaded lwles located

on

the

cable

bracket mounted

on

the gear

lwusing.

Refer

to

the

WESTERBEKE parts

list.
