5.Valves, valve guides and valve seats
(1)Diameter of valve stem
Measure the diameter of the valve stem as
shown in the illustration. If the stem is worn
beyond the limit, or if it is abnormally worn,
replace the valve.
(2)Clearance between valve stem and valve
guide.
The valve guide wears more rapidly at its both
ends than at any other parts. Measure the bore
in the guide for the stem at its ends with an
inside micrometer caliper to find the clearance
between the stem and guide. If the clearance
exceeds the limit, replace the guide or valve
whichever is badly worn.
