CAMSHAFT

b. Cut liquid gasket by prying the position (

) shown in the figure,

and then remove the camshaft bracket.

CAUTION:

• Never damage the mating surface.

• A more adhesive liquid gasket is applied compared to pre-

vious types when shipped, so it should not be forced off

the position not specified.

6. Remove camshafts.
7. Remove valve lifters.

• Identify installation positions, and store them without mixing them up.

8. Remove signal plate from camshaft, if necessary.

INSTALLATION

CAUTION:

Do not reuse O-rings.
1. Install valve lifters.

• Install them in the original positions.

2. Install camshafts.

• Clean camshaft journal to remove any foreign material.

• Distinguish between the intake and the exhaust by looking at

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

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

• Install camshafts so that camshaft dowel pins (A) on the front

side are positioned as shown in the figure.

NOTE:

Though camshaft does not stop at the positions as shown in

the figure, for the placement of cam nose, it is generally

accepted camshaft is placed for the same direction of the fig-

ure.

3. Install camshaft bracket with the following procedure:
a. Remove foreign material completely from camshaft bracket backside and from cylinder head installation

face.

b. Apply liquid gasket (A) to camshaft bracket as shown in the fig-

ure.

Use Genuine RTV silicon sealant or equivalent. Refer to

GI-

c. Tighten mounting bolts of camshaft brackets in the following

steps, in numerical order as shown in the figure.

• There are two types of mounting bolts. Refer to the following

for locating bolts.

Tighten mounting bolts in numerical order.

ii.

Tighten mounting bolts in numerical order.

iii. Tighten mounting bolts in numerical order.

CAUTION:

After tightening mounting bolts of camshaft brackets, be sure to wipe off excessive liquid gasket

from the mating surface of cylinder head.

4. Install the camshaft sprocket to the camshaft with the following procedure.

: 4.0 - 5.6 mm (0.157 - 0.220 in)

CAMSHAFT

a. When the camshaft sprocket (INT) (2) and camshaft sprocket

(EXH) (3) is removed, refer to the paint mark (A) put according

to step “3”. Securely align the knock pin and the pin hole, and

then install them.

b. Tighten bolts in the following steps.

• Secure the hexagonal part of camshaft using wrench to tighten mounting bolt.

Tighten camshaft mounting bolt.

ii.

Turn 30 degrees clockwise (angle tightening).

CAUTION:

Check the tightening angle by using an angle wrench [SST:

KV10112100 (BT8653-A)] (B) or protractor. Never judge by

visual inspection without an angle wrench.

5. Install timing chain and related parts. Refer to

EM-76, "Exploded View"

6. Inspect and adjust valve clearance. Refer to

EM-14, "Inspection and Adjustment"

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

INSPECTION AFTER REMOVAL

Camshaft Runout

1. Put V-block on a precise flat table, and support No. 2 and 5 journal of camshaft.

CAUTION:

Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter

from the other four locations.

2. Set dial indicator (A) vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the

camshaft runout on dial indicator. (Total indicator reading)

4. If it exceeds the limit, replace camshaft.

1. Measure the camshaft cam height with a micrometer (A).

2. If it exceeds the limit, replace camshaft.

Camshaft Journal Oil Clearance

CAMSHAFT JOURNAL OUTER DIAMETER

Measure the outer diameter of camshaft journal with a micrometer

(A).

CAMSHAFT BRACKET INNER DIAMETER

• Tighten camshaft bracket bolts with specified torque. Refer to

EM-89, "Removal and Installation"

• Measure the inner diameter of camshaft bracket with a bore gauge

(A).

CAMSHAFT JOURNAL OIL CLEARANCE

• (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)

• If it exceeds the limit, replace camshaft or cylinder head, or both.

NOTE:

Camshaft bracket cannot be replaced as a single part, because it is machined together with cylinder head.

Replace whole cylinder head assembly.
