Propeller

DESCRIPTION

Propeller
shaft

adopts
solid
tubular
steel
construction

A

correct
balance
of

propeller
shaft
is

very
important

for
a

good
riding
comfort
at

high

speed
Therefore
the

propeller
shafts
in
service

parts
and

ones
assembled
in
the

vehicle

are
counterbalanced
within
an
unbalance
of
IS
gr
cm
0
2
in

oz
at
4

000

rpm
at

the

factory
with

the

best
care

The

propeller
shaft
will
be
unbalanced
if

erroneously

tapped
with
a

hammer
while

servicing
or

flying
rocks
or

bottoming
during
off
road

driving
occurs

CHASSIS

Before

inspecting
various

parts
thoroughly
wash

them

so
that

damage
and
wear

can
be

easily
detected

Then

proceed
as

follows

Check

gear
teeth
for

scoring
cracking
and

chipping

and
make

sure
that
tooth

pattern
indicates

correct

meshing
depth

If

any
defect
is
evident

replace
parts
as

required

Note
Drive

pinion
and
drive

gear
are
supplied
for

replacement
as
a
set
therefore

should
either

part

be

damaged
replace
as
a
set

Check
the

pinion
gear
shaft
and

pinion
gear
mating

faces
for

scoring
and

signs
of
wear
and

replace
as

required

Follow
the
same

procedure
for
inner

faces
of
side

gear

and
their
seats

on
differential
case

3

Inspect
all

bearing
races

and
rollers

for

scoring

chipping
or
evidence
of
excessive
wear

They
should
be

in

tiptop
condition
not
worn
with

mirror
like
surfaces

Replace
if
there
is
a
doubt
on
their

efficiency
since

an

incorrect

bearing
operation

may
result
in
noisiness

and

gear
seizure

PD
Adjusting
drive

pinion

preload

Adjust
the

preload
of
drive

pinion
with

collapsible

spacer

This

procedure
has

nothing
to
do
with
thickness

of

pinion
height
adjusting
washer

Note
Reuse
of
a

collapsible

spacer
must
not
be
allowed

After

adjusting
pinion
height
lubricate

front

bearing

with

gear
oil
and

place
it
in
carrier

2
Install

a
new
oil
seal
in
carrier
Lubricate

cavity

between
seal

lips
with

grease
when

installing

3
Place

a
new

collapsible
spacer
on
drive

pinion
and

lubricate

pinion
rear

bearing
with

gear
oil

4
Insert

companion
flange
into
oil

seal
and

hold
it

firmly
against
pinion
fron

bearing
cone
From
the

rear
of

the
carrier
insert
drive

pinion
into

companion
flange

5
Ascertain
that
threaded

portion
of
drive

pinion
a

new

pinion
nut
and
washer

are
free
from
oil
or

grease

6

Holding
companion
flange
with
Drive
Pinion

Flange

Wrench
ST31540000

tighten
nut
and

then
drive

pinion
is

pulled
into
front

bearing
cone
and

into

flange

As
drive

pinion
is

pulled
into
front

bearing
cone
drive

pinion
end

play
is
reduced

While
there
is
still
end

play
in

drive

pinion
companion
flange
and
cone
will
be
felt
to

bottom
This
indicates
that

bearing
cone
and

companion

flange
have
bottomed
on

collapsible

spacer

From
this

point
a
much

greater
torque
must
be

applied
to
turn

pinion
nut
since

spacer
must
be

collapsed

From
this

point
nut
should
also
be

tightened
very
slowly

and
drive

pinion
end

play
checked
often
so
that

pinion

bearing
preload
does

not
exceed
the
limits

When
the
drive

pinion
end

play
is

eliminated
the

specified
preload
is

being
approached
Replace
collapsible

spacer
if
this

specification
is
exceeded

Note
Do
not
decrease

preload
by

loosening
pinion
nut

This
will

remove
compression
between

pinion
front

and

rear

bearing
cones
and

collapsible
spacer
and

may
permit
front

bearing
cone
to
turn
on
drive

pinion
moreover
nut
becomes
loose
