MAIN BEARING CAP BOLT OUTER DIAMETER





^ Measure the outer diameters (d1, d2) at two positions as shown in the figure.
^ If reduction appears in A range, regard it as d2
Limit (d1 - d2) 0.11 mm (0.0043 inch)
^ If it exceeds the limit (large difference in dimensions), replace main bearing cap bolt with new one.
