Rod Bearing Clearance Inspection
- To check rod bearing-to-journal oil clearance, remove the bearing cap bridge (see CRANKSHAFT AND PISTON REMOVAL ).
- Remove the connecting rod cap and the connecting rod bearing half.
- Clean the connecting rod journal and the connecting rod bearing half with a clean shop towel.
- Place one strip of plastigage across the connecting rod journal.
- Reinstall the bearing half and cap, and torque the bolts to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft) + 90°.NOTE: Do not rotate the crankshaft during inspection. Apply new engine oil to the bolt threads and flanges.
- Remove the rod cap and bearing half, and measure the widest part of the plastigage.
Connecting Rod Bearing-to-Journal Oil Clearance
Standard (New): 0.020-0.038 mm (0.0008-0.0015 in.)
Service Limit: 0.050 mm (0.0020 in.)
- 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(s), and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.
- 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 clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearing, replace the crankshaft (see CRANKSHAFT AND PISTON REMOVAL and start over.
