4.
Using an
inside
micrometer
(Figure
l7)
measure
the camshaft
bearing surfaces
at the 3
different
locations within
each bearing holder
and
cylinder
head
and compare
to dimensions listed
in
Table
5.
5. Using a
micrometer,
measure
the bearing
surfaces on each camshaft
at the 3
different bearing
surface
locations
(Figure
1S)
and compare
to
dimensions
listed
in Table
5.
6. Subtract
the camshaft
OD dimensions taken in
Step 5 from
the camshaft
bearing
journal
dimnsions taken in
Step
4.
This will
give
you
the
bearing clearance.
Compare to dimensions listed
in
Table
5.
7.
Loosen
the camshaft holder
bolts in 2-3
stages
then
remove
the bolts
and the camshaft holders.
8.
If
the camshaft bearing
journals
are
worn
to
the
service limit
dimensions
or
less,
replace
the
camshaft(s) and
recheck
the oil
clearance.
9. If
the oil clearance still
exceeds the service limit,
replace
all camshaft holders
and cylinder head
as a
matched
set.
Installation
Camshaft
installation
is
the same
as on
previous
models
except
for
the
additional bolt
added to each
camshaft
holder.
Be
sure to
install
the 6X62 mm
pin
bolts
(Figure
16) into
their original
position
in
the camshaft holder
and cylinder head. Tighten
the
bolts securing
the
camshaft holders
in
the torque
pattern
shown in Figure 19 in
2-3
stages to the
following
torque specifications:
a. 6
mm
bolts:
10-14 N.m
(7-10
ft.-lb.).
b. 8X 130 mm
bolts:
2l-25 N.m
(15-18
ft.-lb.).
c. 8X
151
mm
bolts:
43-47 N.m
(31-34
ft.-lb.).
d. Cylinder
head
cap
nuts:
30-34 N.m
(22-25
ft.-lb.).
If
the cylinder head was removed,
tighten
the
cap nuts to
this specified
torque
value.
Even if
the
cylinder head
cap
nuts were
not removed,
check
their torque
values.
ROCKER
ARM ASSEMBLIES
The
rocker
arms are
all
identical
(same
Honda
part
No.)
but
they
will
develop different wear
patterns
during
use.
It is
recommended
that
one
rocker
arm assembly
at
a time
be disassembled,
inspected
and
then
assembled
to avoid
interchanging
parts.
Removal/Inspection/Installation
Refer to Figure
20
for
this
procedure.
l.
Unscrew
the
rocker
arm
shaft
plug
(A,
Figure
