CAMSHAFT

13. Remove valve lifters. 

NOTE:
Identify installed positions, and store them without mixing them up.

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 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. Use the "INSTALLATION" procedure.

Standard

:

Less than 0.02 mm (0.0008 in).

Limit

:

0.05 mm (0.0020 in)

• 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. 

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).

• Measure the following parts if out of the standard.
- Dimension “A” for groove of cylinder head No. 1 journal

- 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.

CAMSHAFT

2.

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

• If it exceeds the limit, replace camshaft sprocket.

Valve Lifter 

Check if surface of valve lifter has any wear or cracks.
• If anything above is found, replace valve lifter. Refer to 

EM-148,

"Valve Clearance"

.

Valve Lifter Clearance

VALVE LIFTER OUTER DIAMETER
• Measure the outer diameter of valve lifter with a micrometer (A).

VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head with an
inside micrometer (A).

VALVE LIFTER CLEARANCE
• (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter

outer diameter)

• If out of the standard, referring to the each standard of valve lifter outer diameter and valve lifter hole diame-

ter, replace either or both valve lifter and cylinder head.

• 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.

NOTE:
Though camshaft does not stop at the positions as shown, for
the placement of cam nose, it is generally accepted camshaft
is placed for the same direction as shown.

3.

Remove foreign material completely from camshaft bracket backside and from cylinder head installation
face.

4.

Apply liquid gasket (A) to camshaft bracket as shown.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
