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
