Front
axle
The
dead axle (housings) takes
up
ground
shocks and
supports
the
weight while the live
axle (differential shafts) merely transmits drive
to
front
wheels. All
running
parts are hermeti-
cally enclosed.
At
the
middle
section
of
the
front
axle,
drive flows
in
from
propeller
shaft
to
the
spiral
bevel pinion, ring gear and
the
differential.
The
differential shafts, right and left,
extend
from
the
differential
to
the
front
wheels.

the
housing.
On this gear
case.,
the
final case (carrying the
final
reduction
gearing and the wheel)
is
rotata-
bly
mounted.
Drive
to
the
front
wheel
is
from differential
shaft
to

DISASSEMBLY
A good program
of
diagnosing
is
the
key
to
economy
for the customer. Ask the
operator;
operate
the machine
if
possible;
check
the
machine; picture
the
possible causes; and exam-
ine
them
until
you
can pin-point
the
trouble
before
attempting
to
disassemble the
front
axle.
Removing the universal
joints
To
disconnect
the
propeller
shaft
from the
front axle, remove
the
front
universal
joint,
as
I
follows:
(I)
Remove bolts securing the
upper
and
lower
covers, and
take
down
these covers
to
expose
the
universal
joint.
(2) At the
front
end, remove
the
snap rings and
pull
off
pin from yoke. Push
the
joint
backward, making its
yoke
slide
off
the
pinion
shaft
extending
out
from
the
axle housing, and disconnect the
joint
from
the shaft. Push the
joint
forward and
