1. Remove the oil pump (see «REMOVAL»(ref-360265-S12238473842010042800000) ).
2. 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)
3. 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-360295-S38251644852010042800000) ).
4. To check crankshaft end play, push the crankshaft firmly away from the dial indicator, and zero the dial against the end of the crankshaft. Then pull the crankshaft firmly back toward the indicator; the dial reading should not exceed the service limit. Crankshaft End Play Standard (New): 0.10-0.35 mm (0.004-0.014 in) Service Limit: 0.45 mm (0.018 in)
5. 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-360295-S38251644852010042800000) ).

1. Remove the bearing cap bridge and bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(ref-360295-S38251644852010042800000) ).
2. Clean each main journal and bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal.
4. 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: Apply new engine oil to the bolt threads and flanges. Do not rotate the crankshaft during inspection.
5. Tighten the bearing cap bolts an additional 40 °.
6. 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)
7. 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.
8. 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 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-360295-S38251644852010042800000) ) and start over.
