Connecting Rod Bearing Replacement: Replacement

• M/T
• CVT

2. Place one strip of plastigage across the rod journal.

3. Line up the mark (A) on the connecting rod and the connecting rod cap, then reinstall the connecting rod bearing half and the connecting rod cap and the connecting rod bolts finger-tight.

NOTE: 

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

4. Torque the connecting rod bolts to 20 N.m (2.0 kgf.m, 15 lbf.ft).

Connecting Rod Bearing-to-Journal Oil Clearance 

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

8. If the plastigage shows the clearance is still incorrect, try the next larger or smaller connecting rod 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 connecting rod bearings, replace the crankshaft 

and start over.

2. Numbers have been stamped on the side of each connecting rod as a code for the size of the big end. Use them, and the letters stamped on the crankshaft (codes for rod journal size), to choose the correct connecting rod bearings.

NOTE: 

• If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.
• Each connecting rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.00095 in), in 0.006 mm (0.00024 in) increments) depending on the size of its big end bore. It is then stamped with a number (1, 2, 3, or 4) indicating the range. You may find any combination of 1, 2, 3, or 4 in any engine.

3. Use the big end bore codes and the connecting rod journal codes to select appropriate replacement connecting rod 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.
