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.

i.

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 (INT) to the camshaft (INT) with the following procedure.

a.

When the camshaft sprocket (INT) (2) 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 (INT) using wrench to tighten mounting bolt.

i.

Tighten camshaft (INT) mounting bolt.

ii.

Turn 67 degrees clockwise (angle tightening).

CAUTION:

Check the tightening angle by using an angle wrench [SST:
KV10112100] (B) or protractor. Never judge by visual
inspection without an angle wrench.

INSPECTION AFTER REMOVAL

Camshaft Runout

1.

Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal 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.

Camshaft Cam Height

1.

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

2.

If it exceeds the limit, replace camshaft.

CAMSHAFT

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-173, "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.

Camshaft End Play

1.

Install camshaft in cylinder head. Refer to 

EM-173, "Removal and Installation"

.

2.

Install dial indicator in thrust direction on front end of camshaft.
Read the end play of dial indicator (A) when camshaft is moved
forward/backward (in direction to axis).
