Installation
1) Install tappets and shims to cylinder head.
Apply engine oil around tappet and then install it to
cylinder head.
NOTE
When installing shim, make sure to direct
shim No. side toward tappet.
2) For engine with VVT, install camshaft bearings (1) to
cylinder head (2) and camshaft housing (3).
CAUTION!
Do not apply engine oil to camshaft bearing
back.
Only a upper half bearing of intake camshaft
bearing No.1 has some holes.
3) Install intake camshaft (1) and exhaust camshaft (2).
Align knock pin (3) and match mark (4) with notches
(5) as shown in figure.
NOTE
Before installing camshafts, turn crankshaft
until key position faces upward.
Refer to “Timing Chain and Chain Tensioner
Removal and Installation”.
4) Apply engine oil to sliding surface of each camshaft
and camshaft journal then install them as shown in
figure.

6) Check position of camshaft housings.
Embossed marks are provided on each camshaft
housing, indicating position and direction for
installation. Install housings as indicated by these
marks.
7) After applying engine oil to housing bolts, tighten
them temporarily first. Tighten bolts evenly and
gradually in numerical order (“1” through “21”) by
repeating tightening sequence two or three times
until specified torque is obtained.

Intake Cam Timing Sprocket Assembly (For engine
with VVT)
Fit intake cam timing sprocket assembly to camshaft (2)
and hold hexagonal section of camshaft by using
spanner or the like.

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
