Scheme 701

1. Letters have been stamped on the end of the engine 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 the crank journal codes to select the appropriate replacement bearings from the following table below. NOTE: Color code is on the edge of the bearing.

Scheme 702

1. To check rod bearing-to-journal oil clearance, remove the bearing cap (see «CRANKSHAFT AND PISTON REMOVAL»(ref-295036-S06986309342008081400000) ).
2. Remove the connecting rod cap and the bearing half.
3. Clean the crankshaft rod journal and the bearing half with a clean shop towel.
4. Place plastigage across the rod journal.
5. Reinstall the bearing half and connecting rod cap, and torque the bolts. NOTE: Apply new engine oil to the bolt threads and flanges. Do not rotate the crankshaft during inspection. Tightening Torque: 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft) +90°
6. Remove the connecting rod cap and the 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, 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 clearance 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-295036-S06986309342008081400000) ) and start over.

1. Inspect the connecting rod for cracks and heat damage. Connecting Rod Big End Bore Code Locations
2. Each connecting 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 or bar (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 in either locations.
4. Use the big end bore codes and the rod journal codes to select appropriate replacement bearings from the following table below. NOTE: Color code is on the edge of the bearing.

Cylinder Bore Honing

Only a scored or scratched cylinder core must be honed.

Scheme 723

1. Measure the cylinder bores (see «BLOCK AND PISTON INSPECTION»(ref-295036-S42129787582008081400000) ). If the engine block is to be reused, hone the cylinders and remeasure the bores. Only a scored or scratched cylinder bore must be honed.
2. Hone the cylinder bores with honing oil and a fine (400 grit) stone in a 60 degree cross-hatch pattern. NOTE: Use only a rigid hone with 400 grit or finer stone, such as Sunnen, Ammco, or equivalent. Do not use stones that are worn or broken.
3. When honing is complete, thoroughly clean the engine block of all metal particles. Wash the cylinder bores with hot soapy water, then dry and oil them immediately to prevent rusting. Never use solvent, it will only redistribute the grit on the cylinder walls.
4. If scoring or scratches are still present in the cylinder bores after honing the engine block to the service limit, rebore the engine block. Some light vertical scoring and scratching is acceptable if it is not deep enough to catch your fingernail and does not run the full length of the bore.
