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

Inspect
thrust
washer
faces

Small
defects
can
be
corrected
with

emery

ENGINE

FUEL
PUMP

TESTING

A
fuel

pump
is

operating
properly
when
its

pressure
is

within

specifications
and
its

capacity
is

equal
to
the

engine
5

requirements
at
all

speeds
Pressure
and

cap
lcity
must
be

determined

by
two
tests

with

the

pump
mounted
on
the

engine
Be

sure
that

there

is

gasoline
in
the

tank
when

conducting
these

tests

Fig

test

The

static

pressure
test
is

conducted
as
follows

Disconnect
the
carburetor
fuel
line
at

the
carburetor

2
Install
the

necessary
adapter
and
tee

fitting
to
the

fuel
line

and
attach
a

suitable

pressure
gauge

Start
and
run

engine
at

varying
speeds

The

reading
on
the

the

following

diaphragm
that
is

too

tight

This
condition

requires
removal

of
the
fuel

pump
as

sembly
for

replacement
or

repair

Capacity
test

The

capacity
test

is
used

only
when
the
static

is
within

specifications
The

capacity
test
is
conducted
as

follows

1
Disconnect
