Engine Block: Component Locations Honda Odyssey III

Crankshaft Bore Code Location

Letters or bars have been stamped on the end of the block as a code for the size of each of the four 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.

1. Remove the connecting rod cap and bearing half (see «CRANKSHAFT INSPECTION»(ref-220940-S41437054452006022100000) ).
2. Clean the crankshaft rod journal and bearing half with a clean shop towel.
3. Place a strip of plastigage across the rod journal.
4. Reinstall the bearing half and 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: 20 N.m (2.0 kgf.m, 14 lbf.ft) + 90°
5. Remove the rod cap and bearing half and measure the widest part of the plastigage. Connecting Rod Bearing-to-Journal Oil Clearance Standard (New): 0.020-0.044 mm (0.0008-0.0017 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, then 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 (see «CRANKSHAFT AND PISTON REMOVAL»(ref-220940-S39187594552006022100000) ) and start over.

Connecting Rod Journal Code Locations

Numbers or bars 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 or bars 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.

Scheme 480

1. Measure the cylinder bores (see step 4 ). If the engine block is to be reused, hone the cylinders and remeasure the bores. Only scored or scratched cylinder bores must be honed.
2. J35A7 engine: Remove and discard the oil jets (see «J35A7 ENGINE»(ref-220941-S21298626712006022100000) ).
3. Hone the cylinder bores with honing oil and a fine (400 grit) stone in a 60 degree crosshatch 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.
4. 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.
5. If scoring or scratches are still present in the cylinder bores after honing 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.

3. Remove snap rings (A) from both sides of the piston. Start at the cutout in the piston pin bore. Remove the snap rings carefully so they do not go flying or get lost. Wear eye protection.
4. Heat the piston and connecting rod assembly to about 158°F (70°C), then remove the piston pin.
