- Clean the pistons with liquid soap and water.
- Break the old compression rings in half, then use the compression rings to clean the piston ring groove areas of the piston.
- Inspect the piston ring lands, skirts, oil ring slot corners and pin bosses for scoring, scuffing or cracks. Install a new piston if these types of damage appear.
- Measure keystone piston ring groove wear. Select 2.08 mm (0.082 in) piston gauge pins. Install the gauge pins in the top groove. Using a micrometer, measure the distance between the gauge pins. Install a new piston if not within specification.
- Measure the piston pin diameter in two directions at the points (Scheme 806) Verify the diameter is within specification. If out of specification, install a new piston pin.
- Measure the outside diameter of the piston pin and the inside diameter of the piston pin bore. The difference between the two readings is the piston pin-to-bore clearance. Install a new piston pin or piston if not within specification.

- Using a suitable micrometer, measure the connecting rod bearing bore. Remove the connecting rod bearings from the connecting rod and the connecting rod cap. Install the connecting rod cap onto the connecting rod and tighten the bolts. Further tighten the connecting rod cap bolts. Measure and record the connecting rod bearing bore as indicated. Install new connecting rods if not within specification.
- Using a suitable micrometer, inspect the connecting rod bearing bore taper. Measure the bearing bore inside diameter near the large chamfer. Measure the bearing bore inside diameter near the small chamfer. The difference between the two readings is the bore taper. Install new connecting rods if not within specifications.
