Trouble
shooting,
tune-up,
inspection,
and
repair pro
cedures,
applicable to
all
engines,
are
given
in
this
chapter.
For
the
removal
and
installation
of engine
components,
refer to the
chapter
covering
the
specific
engine.
Inasmuch
as
a determination
of
the
basic
cause of
en
gine
trouble
should
precede
any
repair
work,
the
trouble
shooting
section
is
presented
first.
Many
defects
in
engine
performance
can
be attributed
directly
to a
maladjust
ment
of one
part,
or
a
combination of
parts;
therefore,
general
engine
tune-up
logically
follows the trouble
shoot
ing
section,
and precedes
the
actual repair
work.
1. TROUBLE SHOOTING
Trouble
shooting
is
the application
of
a
definite pro
cedure,
in
a
logical
sequence,
to locate
and eliminate
the
cause of trouble in a
particular system or unit.
It should
be
borne in
mind,
when
trouble
shooting,
to first
look
for
the obvious causes
of
trouble
such
as :
an
empty
gas
tank,
a
wet
or
cold
engine,
loose
or
disconnected
wiring,
or
any
other
such
item
that
may
cause a
temporary
defect.
The various factors
affecting
power
plant
operation
are
outlined
in
this
section.
a.
Engine.
Poor
engine
performance
can
be
attributed
to
the
engine
or
to
forces
on
the
vehicle that
tend
to retard
its motion.
An example
of
a
retarding
force
is
dragging
brakes which
cause
the
engine to
work
harder
and results in poor en
gine
performance.
Engine
performance
depends
on
proper fuel
distribu
tion, correctly
timed
ignition,
normal
and
uniform
com
pression,
properly
regulated flow of
the
fuel-air
mixture
to
the
cylinders,
and
unobstructed
flow
of
exhaust gases.
Engine
trouble
symptoms are
discussed
under
the head
ings
below
with
instructions on what
to
do to correct
the
above
conditions and
regain good
engine
performance.
(1)
ENGINE
WILL
NOT
CRANK. If
the
starter does
not
turn the
engine
over,
or
turns
it
over
too
slowly
to
start,
the
fault is
likely
to
be
in
the
battery
or the
starter.
Perform
the
following
checks
in
the
order
listed,
until
the
cause of
the
trouble
is determined:
(a)
Check the
Battery.
Try
the
horn
or
lights.
If
they
do not
operate
properly,
test the
battery.
Recharge
it,
replace
it,
or
check
further,
as
necessary.
(b)
Check
the
Battery Cables.
Check
for loose or
corroded
connections
at the
starter,
relay,
battery,
and
ground.
Clean, tighten,
or replace
them as
necessary.
(c)
Check
the
Relay
Circuit.
The
relay
contact
surfaces seldom
become so
badly
burned that
they
will
prevent
the
starter
from
cranking
the engine.
However,
other
wiring may
be
at
fault.
Repair
as
necessary.
(Refer
to
Electrical System Section.
)
(d)
Check the
Starter
or
Starter
Drive.
If
the
above
components
are not at
fault,
the
trouble
is prob
ably
in
the starter
or
starter
drive.
If
the
starter
is run
ning,
but not
engaging
the
flywheel,
remove
the
starter
and make
the
necessary
repairs
to
the
starter
drive. In
rare
cases,
the
starter
drive
may
lock
up
with
the
flywheel.
This
can
be corrected
by
loosening
the
starter
and
releas
ing
the
starter drive. If
the starter
does
not
operate,
remove
it
and
make
the
necessary
repairs.

ENGINE

BUT
WILL
NOT

probable
cause
of
