  7. Measure the widest part of the plastic gaging material (1).
  8. If the measurement is too wide or too narrow, remove the upper bearing half and install a new complete bearing of the same color and measure again. Do not file, shim or scrape the bearings or caps to adjust clearance.
  9. If the plastic gaging measurement is still incorrect, try the next larger or smaller bearing. If the correct clearances cannot be obtained, replace the crankshaft assembly.
