The

is

From

the

The

is

screwed

into

the

of

this

The

longitudinal

headers

feed

several

important

points

as

the

oil flows

from

the

rear

to

the

front

of

the

engine.

One

by-pass

is

The

bodies

on

the

and

all

adjacent

connecting

rod

bearings

are

lubricated

by

oil

which

flows

through

the

left

longitudinal

header.

The

two

intermediate

camshaft

bearings

are

lubricated

through

drilled

holes

from

bearings.

The

oil

pump

drive

shaft

is

lubricated

by

oil

which

flows

through

a

drilled

hole

from

the

rear

main

bearing.

At

the

front

end

of

the

left

longitudinal

header

is

a

vertical

header

that

extends

upward

through

the

cylinder

blockand

cylinder

headtothe

leftrocker

arm

shaft.

The

rocker

shafts

are

plugged

at

both

ends

to

prevent

loss

of

oil

pressure.

There

are

two

holes

in

the

rocker

shaftateach

rocker

arm.

One

holeisat

the

bottom

of

the

shaft,

intersecting

a

45

groove

which

distributes

the

oil

evenly

under

the

loaded

area

of

each

rocker

ann.

The

other

bole

is

slightly

mis-matched

withanangular

passage

in

the

rocker

arm,

this

misalignment

acts

as

a

metering

devicetoprevent

excess

oil

heingsupplied

to

the

upper

end

of

the

rocker

arm.

This

angular

passage

in

the

rocker

arm

intersects

a

vertical

passage

which

lubricates

the

push

rod

seat

and

provides

an

exit

for

oil

to

the

top

surface

of

the

rocker

arm,

where

it

flows

slowly

to

the

valve

end

of

the

arm

and

luhricates

the

valve

tip

at

this point.

Oil

from

the

cylinder

heads

drains

backtothe

crankcase

through

either

the

front

or

rear

holes

in

each

cylinder

head

and

matching

holes

in

the

block

leading

directly

to

the

crankcase.

Excess

oil

in

the

valve

lifter

compartment

returns

to

the

crankcase

through

a

drilled

holeatthe

rear

of

the

compartment

on

the

right

side.

A

drilled

and

tapped

hole

at

the

topofthe

left

cylinder

block

near

the

oit

filler

housing

intersects

the

header

which

lubricates

the

leftrocker

arms.

Another

drilled

and

tapped

hole

in

the

oil

filler

housing

is

provided

for

the

oil

filter

outletline.

Oil

from

this line

lubricates

the

fuel

pump

linkage

and

fuel

pump

eccentric.

CRANKCASE

VENTILATION

SYSTEM

--

The

crankcase

ventilatingsystem

provides

positive

air

circulation

through

the

crankcase

at

road

speeds.

With

the

system,

air

enters

the

crankcase

through

the

oil

filler

cap.

This

capisfitted

with

a

copper

mesh air

filter

which

filters

the

dust

out

of

the

air

entering

the

crankcase,

Fig.

10-5.

Airisdrawn

down

through

the

timing

gear

compartment

into

the

crankcase

at

the

crankshaft

level.

Air

andany

con

taminating

vapors

then

pass

up

into

the

valve

lifter

compartment

through

an

opening

in

the

rear

of

the

cylinder

block

between

the

lower

partofthe

crank

case

andvalve

lifter

compartment.

The

air

then

circulates

towardthe

front

of

the

valve

lifter

compartment

andisdrawn

out

through

the

valve

lifter

compartment

cover

channel

to

the

ventilating

pipeatthe

rear

of

the

cover.

This

pipe

extends

below the

rear

of

the

engine

into

the

air

stream

which

creates

a

vacuum,

causing

circula

tion

of

air

through

the

crankcase.

SERVICE

INFORMATION

1

Torque Tightness

The

proper

torque

tightness

of

the

attaching

bolts

and

screws

of

various

engine

parts

is

very

impor

tant

on

all

1954

engines

to

avoid

both

overtighten

ing

and

under-tightening

with

possibledistortion

and

permanent

injury

of

parts.

A

torque

wrench

should

always

be

used

on

the

various

enginebolts

so

that

they

can

be

accurately

tightened

according

to

the

torque

tightness

specifi

cations,

which

are

given

on

after

by

and

washing

b.

Varnish

which

can

be

by

the

NOTE:

The

should

always

be

removed

and

cleaned

when

The
