Connecting Rod Bearing Clearance Inspection
- To check connecting rod bearing-to-journal oil clearance, remove the bearing cap bridge (see CRANKSHAFT AND PISTON REMOVAL ).
- Remove the connecting rod cap and the bearing half.
- Clean the crankshaft rod journal and the bearing half with a clean shop towel.
- Place one strip of plastigage across the connecting rod journal.
- Reinstall the bearing half and the connecting rod cap, then torque the connecting rod bolts to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft) 90°.NOTE:
- Apply new engine oil to the bolt threads and flanges.
- Do not rotate the crankshaft during inspection.
- 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): 0.026-0.044 mm (0.00102-0.00173 in)
Service Limit: 0.050 mm (0.00197 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, 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 that one), and check the 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.
