1. Remove the cam chain (see «CAM CHAIN REMOVAL»(ref-219282-S33731139012006021300000) ).
2. Measure the connecting rod end play with a feeler gauge between the connecting rod and crankshaft. Connecting Rod End Play Standard (New): 0.15-0.30 mm (0.006-0.012 in.) Service Limit: 0.40 mm (0.016 in.)
3. If the connecting rod end play is out-of-tolerance, install a new connecting rod, and recheck. If it is still out-of-tolerance, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-219283-S28525440842006021300000) ).
4. 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 end play is excessive, replace the thrust washers and recheck. If it is still out-of-tolerance, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-219283-S28525440842006021300000) ).

1. Remove the main bearing cap and bearing halves.
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 caps, then torque the bolts to 25 N.m (2.5 kgf.m, 18 lbf.ft) +60°. NOTE: Do not rotate the crankshaft during inspection.
5. Remove the caps and bearings again, and measure the widest part of the plastigage. Main Bearing-to-Journal Oil Clearance No. 1, 4 Journals: Standard (New): 0.014-0.032 mm (0.0006-0.0013 in.) Service Limit: 0.045 mm (0.0018 in.) No. 2, 3 Journals: Standard (New): 0.020-0.038 mm (0.0008-0.0015 in.) Service Limit: 0.050 mm (0.0020 in.)
6. 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.
7. 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 and start over.
