Engine Block: Other Honda Pilot II

Connecting Rod Bearing Selection

Each connecting rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.0009 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/I, II, III or IIII) indicating the range. You may find any combination of 1, 2, 3, or 4/I, II, III, or MM in any engine.

Big End Bore Size: 58.0 mm (2.283 in)

Inspect the connecting rod for cracks and heat damage.

Big End Bore 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 357

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. Remove the oil jets (see «OIL JET REPLACEMENT»(ref-333553-S12487435472009072100000) ).
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. NOTE: 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.
6. Install the oil jets (see «OIL JET REPLACEMENT»(ref-333553-S12487435472009072100000) ).

2. Apply new engine oil to the piston pin snap rings (A) and turn them in the ring grooves until the end gaps are lined up with the cutouts in the piston pin bores (B). NOTE: Take care not to damage the ring grooves.
3. Remove the snap rings (A) from both sides of each 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. Separately heat each piston and connecting rod assembly to about 158°F (70°C), then remove the piston pin.
