16. Without removing the gauging plastic, measure the gauging plastic compressed width at the widest point. Use the graduated scale on the edge of
the gauging plastic envelope.
17. Clearances for crankshaft bearing numbers one, two, three, and four are 0.045-0.083 mm (0.0018-0.0033 inch).
18. Clearances for crankshaft bearing number five are 0.055-0.093 mm (0.0022-0.0037 inch).
19. If the flattened gauging plastic tapers toward the middle or ends, there is a difference in clearance indicating taper, out-of-round, low spot, or other
irregularity of the bearing or journal. Replace the crankshaft if the journal taper or out-of-round exceeds 0.025 mm (0.001 inch).
20. If the bearing clearance is not within specifications, replace the bearing. Always replace both upper and lower bearing inserts as a set.
21. If a bearing is being fitted to an out-of-round journal, be sure to fit to the maximum diameter of the journal. If the bearing is fitted to the minimum
diameter, interference between the bearing and the journal will result in rapid bearing failure.
22. A standard or undersize bearing combination may result in the proper clearance. If the proper bearing clearance cannot be achieved using standard
or undersize bearings, replace the crankshaft.
23. Remove the flattened gauging plastic.
