Professional installation required. Proper assembly is critical for engine reliability:

1. Disconnect battery – Disconnect the negative battery cable before beginning work
2. Drain engine oil and coolant – Drain fluids as necessary
3. Remove the cylinder head – Remove the cylinder head for access to the piston and connecting rod
4. Remove the oil pan – Remove the oil pan for access to the crankshaft and connecting rod bolts
5. Remove the old connecting rod – Mark the cylinder position, remove the connecting rod cap, and carefully push the piston/rod assembly out
6. Inspect the crankshaft journal – Check for wear, scoring, or damage; polish or replace if necessary
7. Inspect the piston pin – Check for wear or damage; replace if necessary
8. Clean thoroughly – Clean all components and oil passages
9. Prepare the new connecting rod – Inspect the new rod and verify it matches the original
10. Install new bearings – Install new connecting rod bearings (upper and lower)
11. Install the piston and rod assembly – Carefully install the piston/rod assembly into the cylinder
12. Install the connecting rod cap – Install the rod cap and torque bolts to manufacturer specifiion
13. Check bearing clearance – Verify bearing clearance using plastigauge (per service manual)
14. Reinstall the oil pan – Install the oil pan with a new gasket
15. Reinstall the cylinder head – Install the cylinder head with a new head gasket
16. Refill fluids – Refill with the correct type and grade of engine oil and coolant
17. Reconnect battery – Reconnect the negative battery cable
18. Start the engine – Start the engine and check for unusual noise or vibration
19. Break-in procedure – Follow the manufacturer's recommended break-in procedure
