Camshaft Runout
Set camshaft between two “V” blocks, and measure its
runout by using a dial gauge.
If measured runout exceeds limit, replace camshaft.
Camshaft runout limit
0.10 mm (0.0039 in.)
Camshaft Journal Wear
Check camshaft journals and camshaft housings for
pitting, scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder
head with housing. Never re place cylinder head without
replacing housings.
Check clearance by using ga uging plastic. Checking
procedure is as follows.
1) Clean housings and camshaft journals.
2) Remove all tappets with shims.
3) Install camshafts to cylinder head.
4) Place a piece of gauging plastic to full width of
journal of camshaft (parallel to camshaft).
5) Install camshaft housing. 6) Install camshaft housing as follows.
After applying engine oil to camshaft housing bolts,
tighten them temporarily first. Then tighten them as
follows.
a) Tighten camshaft housing bolts to 5 N ⋅m (0.5 kgf-
m, 4.0 lb-ft) according to numerical order (“1”
through “21”) as shown in figure.
b) Retighten them by turning through 11 N ⋅m (1.1
kgf-m, 8.0 lb-ft) in same manner as Step a).
NOTE
Do not rotate camshaft while gauging plastic
is installed.

CAUTION!
• When servicing the iridium / platinum
spark plugs (slender center electrode type
plugs), do not touch the center electrode
to avoid damage to it. The electrode is not
strong enough against mechanical force
as it is slender and its material is not
mechanically tough.
• Do not clean or adjust gap for the iridium / platinum spark plugs.

Inspect spark plug for:
• Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found for nickel spark plugs, adjust
air gap, clean with spark plug cleaner or replace them
with specified new plugs.
For iridium / platinum spark plugs, replace them with
new plugs.
