VALVE HEAD RADIAL RUNOUT
Support the valve using a V-block and measure the valve head
radial runout using the dial gauge, as shown. If the runout ex-
ceeds the service limit, replace the valve with a new one.
09900-20606: Dial gauge (1/100 mm)
09900-20701: Magnetic stand
09900-21304: V-block set (100 mm)
Valve head radial runout
Service Limit: 0.03 mm (0.001 in)
VALVE FACE WEAR
Visually inspect each valve face for wear or damage. If any ab-
normal wear is found, replace the respective valve with a new
one. Measure the valve face thickness
T
. If the valve face thick-
ness is not within the specified value, replace the valve with a
new one.

VALVE STEM DEFLECTION
Lift the valve about 10 mm (0.39 in) from the valve seat. Mea-
sure the valve stem deflection in two directions, “X” and “Y”, per-
pendicular to each other. Position the dial gauge as shown. If the
deflection exceeds the service limit, determine whether the valve
or the guide should be replaced with a new one.

Valve stem deflection
Service Limit: 0.35 mm (0.014 in)
VALVE STEM WEAR
Measure the valve stem outside diameter using the micrometer.
If the outside diameter is not within the specified value, replace
the valve with a new one. If the valve stem outside diameter is
within specification, but the valve stem deflection is not, replace
the valve guide with a new one. After replacing the valve or valve
guide, check the deflection.

Standard:
IN: 4.975 – 4.990 mm (0.1959 – 0.1965 in)
EX: 4.955 – 4.970 mm (0.1951 – 0.1957 in)
