    NOTE:  Keep all connecting rod caps and connecting rod bearings in order.

  9. Connecting Rod Bearing Clearance - Inspect

    1. Clean the connecting rod journal and the bearing half with a clean shop towel.

    2. Place plastigage across the rod journal.

    3. Reinstall the bearing half and the connecting rod cap, then torque the bolts to 13 N.m (1.3 kgf.m, 10 lbf.ft) +90 deg..

    NOTE: 

    • Apply new engine oil to the bolt threads and flanges.
    • Do not rotate the crankshaft during inspection.

    4. Remove the connecting rod cap and the bearing half, and measure the widest part of the plastigage.

    Connecting Rod Bearing-to-Journal Oil Clearance 
    Standard (New):  0.020-0.038 mm (0.00079-0.00150 in) 

    5. If the plastigage measures too wide or too narrow, remove the connecting rod cap, and the upper half of the bearing. Install a new, complete bearing with the appropriate color code, and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.

    6. 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 the clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft

    and start over.

  10. Connecting Rod Bearing - Select
    Connecting Rod Big End Bore Code Locations

    1. Inspect each connecting rod for cracks and heat damage.

    2. Each connecting rod has a tolerance range from 0 to 0.024 mm (0.00094 in), in 0.006 mm (0.00024 in) increments, depending on the size of its big end bore. It's then stamped with a number (1, 2, 3, or 4) indicating the range. You may find any combination of numbers in any engine. (Half the number is stamped on the connecting rod cap, the other half is on the connecting rod.) If you cannot read the code because of an accumulation of oil and varnish, do not scrub it with a wire brush or scraper. Clean it only with solvent or detergent.

    Big End Bore Size:  43.0 mm (1.693 in)

    4. Use the big end bore codes and the rod journal codes to select appropriate replacement bearings from the following table.

    NOTE: 

    • Color code is on the edge of the bearing.
    • When using bearing halves of different colors, it does not matter which color is used in the top or bottom.
  11. Connecting Rod Bolt - Inspect

    1. Measure the diameter of each connecting rod bolt at point A and point B.

    2. Calculate the difference in diameter point A and point B.

    3. If the difference in diameter in out of specification, replace the connecting rod bolt.

    Point A - Point B = Difference in Diameter 
    Difference in Diameter 
    Specification:  0-0.05 mm (0-0.0020 in) 
  12. Connecting Rod Cap and Bearing Half - Install

    1. Apply new engine oil to the threads of the connecting rod bolts.

    2. Seat the rod journals into connecting rod No. 1 and connecting rod No. 4. Line up the mark (A) on the connecting rod and the connecting rod cap.

    3. Install the connecting rod caps and the bolts finger-tight.

    4. Rotate the crankshaft clockwise, and seat the journals into connecting rod No. 2 and connecting rod No. 3. Line up the mark on the connecting rod and the connecting rod cap.

    5. Install the connecting rod caps and the bolts finger-tight.

    6. Torque the connecting rod bolts to the specified torque.

    7. Tighten the connecting rod bolts an additional 90 deg..

    NOTE:  Remove the connecting rod bolt if you tightened it beyond the specified angle, inspect the connecting rod bolts. Do not loosen it back to the specified angle.

    Specified Torque: 
    13 N.m (1.3 kgf.m, 10 lbf.ft) 
  13. All Removed Parts - Install
    1. Install the parts in the reverse order of removal.
