#### Tools Required

J 8087 Cylinder Bore Gauge

1. Clean the following components:

• | Use solvent to clean the engine block.

• | Clean the gasket surfaces.

• | Clean the coolant passages.

• | Clean the oil passages.

2. Inspect the following for cracks:

• | Inspect the cylinder walls for cracks.

• | Replace the engine block if any cracks are evident.

• | Inspect the coolant jackets for cracks.

• | Replace the engine block if any cracks are evident.

• | Inspect the main bearing insert cavities for cracks.

• | Replace the engine block if any cracks are evident.

3. Inspect for the following in the cylinder walls:

• | Inspect for gouges in the cylinder walls deeper than 0.05 mm (0.002 in).

• | Bore the cylinder if gouges are deeper than 0.05 mm (0.002 in).

• | Inspect for pitting in the cylinder walls deeper than 0.05 mm (0.002 in).

• | Bore the cylinder if pitting is deeper than 0.05 mm (0.002 in).

• | Inspect for scores is the cylinder walls deeper than 0.05 mm (0.002 in).

• | Bore the cylinder if scores are deeper than 0.05 mm (0.002 in).

4. Use the J 8087 to measure the cylinder bore at the directed points (1, 2) for the following conditions:

• | Measure for wear.

• | Measure for taper.

• | Measure for runout.

• | Measure for ridging.

5. The cylinders with less than 0.05 mm (0.002 in) of wear and/or taper may be reconditioned.
6. Recondition the cylinders with less 0.05 mm (0.002 in) with a hone and fitted with the appropriate size select fit piston (providing the cylinder was not fitted with the largest size select fit piston).
