1. Remove the oil pump (see «OIL PUMP REMOVAL»(ref-291390-S09577982152008072800000) ).
2. Measure the connecting rod end play with a feeler gauge between the connecting rod and the 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-291421-S33744286702008072800000) ) .
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 the end play is out-of-tolerance, replace the thrust washers and recheck, if it is still out-of-tolerance, replace the crankshaft (see «CRANKSHAFT AND PISTON REMOVAL»(ref-291421-S33744286702008072800000) ) .

Scheme 201

1. To check main bearing-to-journal oil clearance, remove the bearing cap bridge and bearing halves (see «CRANKSHAFT AND PISTON REMOVAL»(ref-291421-S33744286702008072800000) ) .
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 torque the bolts to 25 N.m (2.5 kgf.m, 18 lbf.ft) +40°. NOTE: Do not rotate the crankshaft during inspection.
5. 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.)
6. 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.
7. 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.

1. Letters 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.
3. Use the crank bore codes and crank journal codes to select the appropriate replacement bearings from the following (Scheme 204). NOTE: Color code is on the edge of the bearing.

1. To check rod bearing-to-journal oil clearance, remove the bearing cap bridge (see «CRANKSHAFT AND PISTON REMOVAL»(ref-291421-S33744286702008072800000) ) .
2. Remove the connecting rod cap and bearing half.
3. Clean the crankshaft rod journal and bearing half with a clean shop towel.
4. Place plastigage across the rod journal.
5. 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.
6. 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.)
7. 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.
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 clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearing, replace the crankshaft and start over.

Scheme 208

1. Inspect each connecting rod for cracks and heat damage. Connecting Rod Big End Bore Code Locations
2. Each rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.0009 in.), in 0.006 mm (0.0002 in.) increments) depending on the size of its big end bore. It's then stamped with a number (1,2, 3, or 4) indicating the range. You may find any combination of 1,2,3, or 4 in any engine. 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. Normal Bore Size: 43.0 mm (1.69 in.) Connecting Rod Journal Code Location
3. The connecting rod journal codes are stamped on the crankshaft.
4. Use the big end bore codes and rod journal codes to select appropriate replacement bearings from the following (Scheme 208). NOTE: Color code is on the edge of the bearing.

11. Remove the rod caps/bearings. Keep all caps/ bearings in order.
12. Lift crankshaft out of the engine block, be careful not to damage the journals.
13. Remove the upper bearing halves from the connecting rods, and set them aside with their respective caps.
14. Use the wooden handle of a hammer (A) to drive out the pistons (B).
15. Reinstall the bearing cap bridge and the bearings on the engine block.
16. Reinstall the connecting rod bearings and caps after removing each piston/connecting rod assembly.
17. To avoid mix up on reassembly/ mark each piston/ connecting rod assembly with its cylinder number.

Note. The existing number on the connecting rod does not indicate its position in the engine block, it indicates the rod bore size.
