- Remove the oil pump (see «REMOVAL»(ref-320427-S18493704202009071400000) ).
- Measure the connecting rod end play with a feeler gauge (A) between the connecting rod (B) and the crankshaft (C). Connecting Rod End Play Standard (New): 0.15-0.35 mm (0.006-0.014 in.) Service Limit: 0.40 mm (0.016 in.)
- If the connecting rod end play is beyond the service limit, install a new connecting rod, and recheck. If it is still beyond the service limit, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-320456-S36456649982009071400000) ).
- To check crankshaft end play, push the crankshaft firmly away from the dial indicator by prying, and zero the dial against the end of the crankshaft. Then pull the crankshaft firmly back toward the indicator by prying; the dial reading should not exceed the service limit. Crankshaft End Play Standard (New): 0.10-0.35 mm (0.0039-0.0138 in.) Service Limit: 0.45 mm (0.0177 in.)
- If the end play is beyond the service limit, replace the thrust washers and recheck, if it is still beyond the service limit, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-320456-S36456649982009071400000) ).

- To check main bearing-to-journal oil clearance, remove the bearing cap bridge and bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(ref-320456-S36456649982009071400000) ).
- Clean each main journal and bearing half with a clean shop towel.
- Place one strip of plastigage across each main journal.
- Reinstall the bearings and bearing cap bridge, then tighten the bearing cap bolts to 25 N.m (2.5 kgf.m, 18 lbf.ft) in the proper sequence. NOTE: Do not rotate the crankshaft during inspection. Apply new engine oil to the bolt threads and flanges.
- Tighten the bearing cap bolts an additional 40°.
- Remove the bearing cap bridge and bearings again, and measure the widest part of the plastigage. Main Bearing-to-Journal Oil Clearance Standard (New): 0.018-0.036 mm (0.0007-0.0014 in.) Service Limit: 0.050 mm (0.0020 in.)
- If the plastigage measures too wide or too narrow, remove the crankshaft, and 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 again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-320456-S36456649982009071400000) and start over.

- Letters have been stamped on the end of the engine block as a code for the size of each of the five main journal bores. Write down the crank bore codes. Use them, and the numbers stamped on the crankshaft (codes for main journal size), to choose the correct main bearings. 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.
- The main journal codes are stamped on the crankshaft.
- Use the crank bore codes and crank journal codes to select the appropriate replacement bearings from the following table below. NOTE: Color code is on the edge of the bearing.

- To check rod bearing-to-journal oil clearance, remove the bearing cap bridge (see «CRANKSHAFT AND PISTON REMOVAL»(ref-320456-S36456649982009071400000) ).
- 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»(ref-320456-S36456649982009071400000) and start over.
