Cylinder (Upper Crankcase) Wear Inspection

Since there is a difference in cylinder wear (upper crankcase) in different directions, take a side-to-side and a front-to-back measurement at each of the two locations (total of four measurements) as shown in the figure.

If any of the cylinder inside diameter measurements exceeds the service limit, replace the crankcase.

Standard: 75.994 76.006 mm
(2.9919 2.9924 in.)
