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.

connecting rod bearings, pistons, piston
rings and cylinder bores.
• Journal bearings, bearing caps, connecting rods, rod bearings, rod bearing
caps, pistons and piston rings are in
combination sets. Do not disturb such
combination and make sure that each part
goes back to where it came from, when
installing.
