Removal
CAUTION!
After timing chain is removed, never turn
crankshaft and camshafts independently
more than its allowable turning range
described in “Installation”.
If turned, interferen ce may occur between
piston and valves and valves themselves,
and parts related to piston and valves may be
damaged.
1) Remove timing chain cover referring to “Timing Chain Cover Removal and Installation”.
2) By turning crankshaft, align camshafts and crankshaft at specific position as follows.
a) Align both intake and exhaust camshaft timing sprocket marks (1) with notches (2) of cylinder
head respectively.
b) Align crankshaft sprocket key (3) with notch of cylinder block (4).
Position crankshaft sprocke t key (3) at upside of
crankshaft as shown in figure.
3) Remove timing chain tensioner adjuster assembly (5).
4) Remove timing chain tensioner (6).
5) Remove timing chain No.1 guide (7).
6) Remove timing chain (8) with crankshaft timing sprocket (9). Installation
CAUTION!
After timing chain is removed, never turn
crankshaft and camshafts independently
more than such an extent (“a”, “b”) as shown
in figure.
If turned, interferen
ce may occur between
piston and valves and valves themselves,
and parts related to piston and valves may be
damaged.
1) Check that match marks (1) on intake and exhaust camshaft timing sprockets are in match with notches
(2) on cylinder head as shown in figure.
2) Set key (3) and turn crankshaft to position key on upside of crankshaft.

CAUTION!
Do not apply engine oil to camshaft bearing
back.
Only a upper half bearing of intake camshaft
bearing No.1 has some holes. Other
bearings.

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.
