Abstract
The present invention provides a method and a device for accurately measuring and adjusting a valve clearance value to a desired value in an engine having a rocker-arm-type valve. According to a valve clearance measuring and adjusting method of the present invention, a pair of probeseach having a round tip endare brought into direct contact with a valve clearance CV of an engine having a rocker-arm-type valve, and a center-to-center distance between the two tip endsis measured. An actual valve clearance value is calculated and measured on the basis of the center-to-center distance between the tip ends. The actual valve clearance value is adjusted to a desired valve clearance value, while the actual valve clearance value is measured in real time.
