• The piston, piston ring and connecting rod cannot be disassembled.
• When replacing the piston, piston pin, piston ring and connecting rod, replace them together as a single unit.

1. Install the connecting rod cap. (See Connecting Rod Cap Assembly Note.)

2. Measure the connecting rod large end side clearance.

• If the connecting rod large end side clearance exceeds the maximum clearance, replace the piston, piston pin, piston ring and connecting rod as a single unit.
Standard clearance:
0.14-0.36 mm {0.0056-0.0141 in}
Maximum clearance:
0.435 mm {0.0172 in}

3. Remove the connecting rod cap.

4. Position plastigage atop the journals in the axial direction.

5. Install the connecting rod bearing and connecting rod cap. (See Connecting Rod Cap Assembly Note.)

6. Remove the connecting rod cap.

7. Measure the connecting rod oil clearance.

• If not as specified, replace the connecting rod bearing or grind the crank pin and use oversize bearings so that the specified clearance is obtained.
Standard clearance:
0.026-0.052 mm {0.0011-0.0020 in}
Maximum clearance:
0.1 mm {0.0039 in}
