MAINTENANCE--ENGINE
Torsion damper
inspection
Check the torsion damper
for
deformation
or any
other
damages.
Check the
damper rubber
if
it
is
not
cracked or otherwise
damaged.
If there is any
damage
on the torsion
damper by
visual
check,
replace it.
A. Damper Rubber
SECONDARY SHAFT, SECONDARY CHAIN,
TIMING CHAIN
The secondary shaft
has
the oil
pump drive gear,
ti
ming chain
and cam chain sprockets,
coupling,
and
secondary chain
drive
sprocket
on
it.
I
t is supportedby two
journals
on
the
timing
chain
and
cam chain sprockets and secondary chain
drive
sprocket.
The timing chain transfers
power
to
the
oil
pump
drive shaft for working
the
oil
pump and
timing
advancer.
Secondary shaft bearing
insert/journal
wear
eSpl
it
the crankcases,
and
clean off the
each
journal,
bearing
inserts,
and
mating
surface
of
crankcase
halves.
-Cut
strips of
plastigauge
to each
bearing
insert
width
.
Place strips on
each journals
parallel to the secondary
shaft so
the plastigauge
strips
will be compressed
be·
tween
the bearing
inserts
and the crankshaft
journals.
A. Plastigauge
e
lnstall the
lower crankcase
half without
turning
the
secondary
shaft,
and
tighten the bolts
in
the
correct
sequence to the specified amount of torque (Pg. 101).
e
Remove the
lower
crankcase half (making sure that the
crankshaft
does not turn at any
time),
and measure
each plastigauge width to determine the bearing
insert/
journal
wear.
e
lf any
clearance
exceeds the service limit,
replce all
bearing
inserts
(4),
and check the
secondary shaft
journals.
Table H53
Secondary Shaft Bearing Insertl
Journal Clearance
Service Limit
0.11 mm
eMeasure the
journal
diameters.
If the micrometer
reading
is
less than
the
service limit, replace
the timing
chain and cam chain sprockets, and/or
the secondary
chain
drive
sprocket.
A. Journals
Table H54
Secondary Shaft Journal Diameter
Service Limit

I
Primary chain driven sprocket, timing chain
and cam chain sprockets, secondary chain
drive sprocket, oil pump drive gear
Visually
inspect
the teeth
on
each sprocket
and
gear.
Any light damage
can
be corrected with an oilstone, but
the sprockets and gear must be
replaced
if the teeth are
badly damaged. Damaged teeth on each sprocket
indio
cates that the chain which
runs
on the sprocket may
also
be damaged
.
When these sprockets and gear are
repaired
or replaced, the
corresponding
gear or sprocket
on the
same
chain
should also
be
inspected,
and
repaired
or
replaced
as necessary.
