• If the calculated value exceeds the limit, replace valve and/or valve guide. When valve guide must be
EM-102, "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-102, "Disassembly and Assem-
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-11, "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.
