    		 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 connecting rod bolt to 20 N.m (2.0 Kgf-m, 15 lbf/ft) + 90°.

    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): 0.020-0.044 mm (0.00079-0.00173 in) 
    Service Limit: 0.050 mm (0.00197 in) 

    5. If the plastigage measures too wide or too narrow, remove the upper half of the bearing. Install a new, complete bearing with the same 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 that one), and check the clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the Crankshaft - Removal and Installation  and start over.
