DESCRIPTION

The
rear
axle

assembly
is
of

the

semi

floating

type
in

which
the
vehicle

weight
is

carried
on
the
axle
shafts

through

bearings
enclosed
in
the

bear

ing
cages
on
outer

rear
axle

case
The

axle
case
is
a

pressed
steeJ

Banjo

type
housing

The

rear
axle

assembly
is

attached

to
the
frame

through
semi

elliptic
leaf

springs
and

telescopic
hydraulic
shock

absorbers

Rubber

bushings
at

either

end
of

the
leaf

springs
and
shock

absorbers

are

designed
to
absorb
vibra

tion
and
noise

The
rear

axle
shaft

splines

engage

the
differential

side

gears
with

a
float

ing
fit
The

outer
ends
are

supported

in
the

bearing
cages
by
tapered
roller

bearings

The

bearings
are
lubricated

by

wheel

bearing
grease
The
axle
shaft
oil

seals

are
located

outboard
and

inboard

of
the

bearing
The

bearings
are

se

cured

against
shoulders

on
the
shafts

by
press
fit

and
held
in

place
by
a

large
nuts

The

bearing
cages
hold
the

bearings

against
shoulders
on
the
axle

case

Whee
side

is
taken

at
the

wheel

bearings

through
the
thrust

block
so
an
axle
shaft

may
be

re

moved

simply
by

DESCRIPTION

Model
CF206
is
a
crank

type

compressor
specially
designed
with

minimum
size
and

light
weight
for

use

on

compact
vehicles

The

compressor
crankshaft
is

driven

by
a
belt
from
the
crankshaft

pulley

through
the

electromagnetic
clutch

Two

pistons
positioned
in

line
are

actuated

by
connecting
rods
coo

nected
to
the
crankshaft

Discharge
and
suction
valves
are

mounted
in
the

valve
liner
between
the

crankcase
and

cylinder
head

As
a
lubricant

SUNlSO
NO
5
is

used

Simplified
positive
pressure

lubrication
utilizes

existing
pressure

differential
between
suction

intake

and
crankcase
to

provide
a
film
of

lubricating
oil
to

bearings
All
internal

components
have
been

designed
to

provide
more
than

adequate
lubrica

tion
to

cylinder
walls

connecting
rod

bearings
and
seal

assembly
The
result

is

improved
lubrication
lower

seal

temperatures
reduced
oil

pumping

and
a

reduction
in
the
number

of

moving
parts
