CAMSHAFT

a.

When the camshaft sprocket (INT) 

 and camshaft sprocket

(EXH) 

 is removed, refer to the paint mark 

 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.

i.

Tighten camshaft mounting bolt.

ii.

Turn 30 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.

5.

Install timing chain and related parts. Refer to 

EM-183, "Exploded View"

.

6.

Inspect and adjust valve clearance. Refer to 

EM-133, "Inspection and Adjustment"

.

7.

Install remaining parts in the reverse order of removal.

Inspection

INFOID:0000000010715504

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-197, "Removal and Installation"

.

• Measure the inner diameter of camshaft bracket with a cylinder

gauge .

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.

- Dimension (B) for camshaft flange

• Refer to the standards above, and then replace camshaft and/

or cylinder head.

Camshaft Sprocket Runout

1.

Put V-block on precise flat table, and support No. 2 and 5 journals 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.

Measure the camshaft sprocket runout with a dial indicator (A).
(Total indicator reading)

• If it exceeds the limit, replace camshaft sprocket.
