  3. Using the J 8087:  gage, measure the cylinder bore for oversize.

    Slide the bore gage up and down throughout the length of the cylinder bore. Measure the bore both parallel and perpendicular to the centerline of the crankshaft at the top, center, and bottom of the bore. A cylinder bore that exceeds the maximum diameter must be serviced with an oversized piston. Refer to Engine Mechanical Specifications .
