CAMSHAFT

b. Pry at the position of the (

) in the figure to cut away the liquid

gasket, and remove the camshaft bracket.

CAUTION:

A liquid gasket more adhesive than previous types is

applied when shipped, so never force it off of a position not

specified.

6. Remove camshaft.
7. Remove valve lifter.

• Identify installation position of each valve. Arrange removed valves so that they cannot be mixed up.

8. If necessary, remove the camshaft signal plates from the camshaft.

INSTALLATION

1. Install valve lifter.

• If reused, install in the original position.

2. Install camshaft.

• Clean the journal to remove any foreign material, dust, and oil.

• Distinguish between the intake and the exhaust by looking at

the different shapes of the front and rear ends of the camshaft

or by using the identification colors (A) and (B).

• Install camshafts to the cylinder head so that knock pin (A) on

front end is positioned as shown in the figure.

NOTE:

The knock pin does not stop at the position facing straight up

due to the camshaft nose location. Therefore, it is generally

acceptable for the position of the knock pin to be almost at the

upper side.

3. Install camshaft bracket according to the following procedure.
a. Remove foreign material completely from the back of camshaft bracket and cylinder head mounting sur-

face.

b. Apply a continuous bead of liquid gasket (A) (ThreeBond 1217H

or equivalent) to the position shown in the figure, while checking

for overlaps.

c. Tighten camshaft bracket bolts evenly in three steps in the order

as shown in the figure.

NOTE:

There are two types of bolts. Refer to the following when install-

ing bolts.

CAUTION:

After tightening the mounting bolts, wipe away any liquid gasket that is squeezed out.

4. Install the camshaft sprocket onto the camshaft according to the following procedure.
a. Refer to the marks (A) that are put when the sprockets are

removed, and securely align the camshaft (INT) knock pins with

the camshaft sprocket (INT) (2) pin holes, and the camshaft

(EXH) knock pins with the camshaft sprocket (EXH) (3) pin

holes, before installing.

b. Tighten bolts in the following order.

CAMSHAFT

Hold the camshaft hexagonal part, and then secure the camshaft.

i.

Tighten the camshaft sprocket mounting bolt.

ii.

Tighten by a further 30

° (angle tightening).

CAUTION:

Check tightening angle with an angle wrench [SST:

KV10112100 (BT8653-A)] (B) or a protractor. Never estimate

tightening angle visually.

5. Install parts related to the timing chain. Refer to 

EM-248, "Exploded View"

.

6. Perform inspection and adjustment of valve clearance. Refer to 

EM-179, "Inspection and Adjustment"

.

7. Install removed parts in the reverse order of removal.

CAUTION:

When replacing camshaft, remove the 2D code label from the electric throttle control actuator and

clear the valve timing variation value. Refer to 

EC-756, "Work Procedure"

.

Inspection

INSPECTION AFTER REMOVAL

Camshaft Runout

• Set a pair of V-blocks on a level surface and support journals No. 2 and 5 of camshaft.

CAUTION:

Because journal No. 1 (camshaft sprocket side) has a different diameter from the other four loca-

tions, do not support it.

• Set a dial indicator (A) vertically onto journal No. 3.

• Rotate camshaft one rotation and read indication on the indicator.

• Replace camshaft if the limit is exceeded.

Camshaft Nose Height

• Measure with a micrometer (A).

• Replace camshaft if the value is outside (less than) the limit.

Camshaft journal outer diameter

• Measure with a micrometer (A).

Camshaft bracket inner diameter

• Tighten camshaft bracket bolts to the specified torque.

• Measure inner diameter of the camshaft bracket using a bore

gauge (A).

How to calculate camshaft oil clearance

(Oil clearance ) = (Camshaft bracket inner diameter) - (Camshaft journal outer diameter)

• If the limit is exceeded, replace camshaft and/or cylinder head. Refer to the standards for each unit.

NOTE:

Because camshaft bracket is machined together with cylinder head, replace it as a cylinder head assembly.

Camshaft End Play

• Set a dial indicator (A) to the camshaft front end in thrust direction.

Move the camshaft back and forth (in axial direction) and read indi-

cation on the indicator.
