  • Patent number: 8467989
    Abstract: The present invention provides a method for measuring a clearance (13) between facing surfaces of a first member (11) and a second member (12). The method includes a step (S1) of bringing a pair of probes each having a tip end (14) slightly larger than the clearance (13) into direct contact with the clearance (13) and measuring a separation distance between the two tip ends (14), and a calculating step (S2) of calculating and measuring a clearance value (d1) on the basis of the separation distance between the tip ends (14).

  • Patent number: 8316699
    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 probes 60 each having a round tip end 611 are brought into direct contact with a valve clearance CV of an engine having a rocker-arm-type valve 105, and a center-to-center distance between the two tip ends 611 is measured. An actual valve clearance value is calculated and measured on the basis of the center-to-center distance between the tip ends 611. The actual valve clearance value is adjusted to a desired valve clearance value, while the actual valve clearance value is measured in real time.
