    INSPECT CYLINDER HEAD SET BOLT


    1. w/ Washer:


      1. A003FXTE01

        Using a vernier caliper, measure the thread outside diameter of the cylinder head set bolt.

        Minimum diameter
        11.4 mm (0.449 in.)
        Table 1. Text in Illustration
        *a Measuring Area
        *b Washer

        If the diameter is less than the minimum, replace the cylinder head set bolt.
