Inspection

INFOID:0000000009753616

INSPECTION AFTER REMOVAL

Cylinder Head Bolts Outer Diameter

• Cylinder head bolts are tightened by plastic zone tightening

method. Whenever the size difference between (d1) and (d2)
exceeds the limit, replace them with a new one.

• If reduction of outer diameter appears in a position other than (d2),

use it as (d2) point.

Cylinder Head Distortion

NOTE:
When performing this inspection, cylinder block distortion should be also checked. Refer to

EM-120, "Inspec-

tion"

Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.

CAUTION:

Never allow gasket debris to enter passages for engine oil or water.

At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions using straightedge (A)
and feeler gauge (B).

• If it exceeds the limit, replace cylinder head.

INSPECTION AFTER DISASSEMBLY

VALVE DIMENSIONS

• Check the dimensions of each valve. For the dimensions, refer to

EM-139, "Cylinder Head"

• If dimensions are out of the standard, replace valve and check valve seat contact. Refer to “VALVE SEAT

CONTACT”.

VALVE GUIDE CLEARANCE

Valve Stem Diameter

• Measure the diameter of valve stem with micrometer (A).

Valve Guide Inner Diameter

• Measure the inner diameter of valve guide with bore gauge.

Valve Guide Clearance

• (Valve guide clearance) = (Valve guide inner diameter) – (Valve

stem diameter)

Limit [(d1) – (d2)]: 0.15 mm (0.0059 in)

• If the calculated value exceeds the limit, replace valve and/or valve guide. When valve guide must be

replaced. Refer to

EM-99, "Disassembly and Assembly"

VALVE SEAT CONTACT

• After confirming that the dimensions of valve guides and valves are within the specifications, perform this

procedure.

• Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the valve

contact on the surface.

• Check if the contact area band is continuous all around the circum-

ference.

• If not, grind to adjust valve fitting and check again. If the contacting

surface still has “NG” conditions (B) even after the recheck,
replace valve seat. Refer to

EM-99, "Disassembly and Assembly"

VALVE SPRING SQUARENESS

• Set a try square (A) along the side of valve spring and rotate

spring. Measure the maximum clearance between the top of spring
and try square.

• If it exceeds the limit, replace valve spring.

VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD

• Check valve spring pressure with valve spring seat installed at the

specified spring height.

CAUTION:

Never remove valve spring seat from valve spring.

• If the installation load or load with valve open is out of the stan-

dard, replace valve spring (with valve spring seat).

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to

MA-10, "Fluids and Lubricants"

• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including

engine oil and engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the

specified level, if necessary.
