MEASUREMENTS 1. Using micrometer ball attachment (Figure 3, Item 18), measure thickness of bearing shells (Figure 3, Items 10 and 11) at point (C), 90 degrees from parting line. Replace if minimum thickness is less than 0.1230 in. (3.124 mm). A standard bearing is 0.1240–0.1245 in. (3.150–3.162 mm) thick, refer to Table 1 for thickness of bearings. Table 1.
