Crankshaft Main Bearing Replacement

1. Remove the lower block and the bearings again, and measure the widest part of the plastigage.

   Main Bearing-to-Journal Oil Clearance
   No. 1, 5 Journals:
   Standard (New): | 0.014 − 0.030 mm (0.0006 − 0.0012 in.)
   Service Limit: | 0.040 mm (0.0016 in.)
   No. 2, 3, 4 Journals:
   Standard (New): | 0.018 − 0.034 mm (0.0007 − 0.0013 in.)
   Service Limit: | 0.045 mm (0.0018 in.)

1. If the plastigage measures too wide or too narrow, remove the crankshaft, and remove the upper half of the bearing. Install a new, complete bearing with the appropriate color code(s), and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.

1. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below the current one), and check again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft, and start over.
