1. Remove the oil pump.
2. Remove the baffle plates (see step 7).
3. Measure the connecting rod end play with a feeler gauge between the connecting rod and crankshaft.
Connecting Rod End Play
Standard (New): 0.15-0.35 mm (0.006-0.014 in.)
Service Limit:. 0.40 mm (0.016 in.)
4. If the connecting rod end play is beyond service limit, install a new connecting rod, and recheck. If it is still beyond service limit; replace the crankshaft.
5. 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.)
6. If the end play is beyond service limit, replace the thrust washers and recheck, if it is still beyond service limit, replace the crankshaft.
Crankshaft Main Bearing Replacement
Main Bearing Clearance Inspection
1. To check main bearing-to-journal oil clearance, remove the lower block 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 lower block, then torque the bolts to 29 N*m (3.0 kgf*m, 22 Ibf*ft).
NOTE: Do not rotate the crankshaft during inspection.
5. Tighten the bearing cap bolts an additional 56º.
6. Remove the lower block and bearings again, and measure the widest part of the plastigage.
Main Bearing-to-Journal Oil Clearance
No.1, 2, 4, 5 Journals:
Standard (New): 0.017 - 0.041 mm
(0.0007 - 0.0016 in.)
Service Limit: 0.050 mm (0.0020 in.)
No.3 Journal:
Standard (New): 0.025 - 0.049 mm
(0.0010 - 0.0019 in.)
Service Limit: 0.055 mm (0.0022 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 appropriate 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 the current 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.
Main Bearing Selection
Crankshaft Bore Code Location
1. Numbers, letters, or bars have been stamped on the end of the block as a code for the size of each of the five main journal bores. Write down the crank bore codes.
If you can't read the codes because of accumulated dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.
Main Journal Code Location
2. The main journal codes are stamped on the crankshaft in either location.
3. Use the crank bore codes and crank journal codes to select the appropriate replacement bearings from the following table.
NOTE:
