Scheme 235

1. Remove the oil pump (see «OIL PUMP OVERHAUL»(ref-173105-S35418340972005030900000) ).
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 «Oil Pan Removal»(ref-173102-S07541859882005030900000) ).
4. Mount a dial indicator on the block so that its tip contacts the end of 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 excessive, replace the thrust washers and recheck. If it is still out-of-tolerance, replace the crankshaft (see «Oil Pan Removal»(ref-173102-S07541859882005030900000) ).

Scheme 236

1. Remove the main caps 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. NOTE: If the engine is still in the car when you bolt the main cap down to check the clearance, the weight of the crankshaft and drive plate will flatten the plastigage further than just the torque on the cap bolt and give you an incorrect reading. For an accurate reading, support the crank with a jack under the counterweights, and check only one bearing at a time.
4. Reinstall the bearings and caps, then torque the bolts to 51 N.m (5.2 kgf.m, 38 lbf.ft). Do not rotate the crankshaft.
5. Remove the cap and bearing half, and measure the widest part of the plastigage. Main Bearing-to-Journal Oil Clearance Standard (New): No. 1, 5: 0.018-0.036mm (0.0007-0.0014 in.) No. 2, 3, 4: 0.024-0.042mm (0.0009-0.0017 in.) Service Limit: 0.05 mm (0.002 in.)
6. If the plastigage measures too wide or too narrow, (remove the engine if it's still in the car), remove the crankshaft, and remove the upper half of the bearing. Install a new, complete bearing with the same color code, 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 (see «Oil Pan Removal»(ref-173102-S07541859882005030900000) ).

Crankshaft Bore Code Location

Letters have been stamped on the end of the block as a code for the size of each of the five main journal bores.

Use them, and the numbers stamped on the crankshaft (codes for main journal size), to choose the correct 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.

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, 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 clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over (see «Oil Pan Removal»(ref-173102-S07541859882005030900000) ).

Connecting Rod Journal Code Locations

Numbers have been stamped on the side of each connecting rod as a code for the size of the big end. Use them, and the letters stamped on the crank (codes for rod journal size), to choose the correct 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.
