2. Automatic transmission - remove flange.
3. Install the engine on a special stand for disassembly.
4. Remove the drive belt.
5. Remove the cylinder head.
6. Remove the oil dipstick (A).
7. Remove the knock sensor (A).
8. Remove the oil pressure sensor (A).
9. Remove the water pump.
10. Remove the crankcase (A).
11. Loosen the two bolts (C) and remove the oil intake (A) with the gasket (B).
12. Check the axial clearances of the connecting rods (see section "Checking the technical condition" in the cylinder block of the G6BA engine).
13. Remove the connecting rod caps and check the clearance between the crankshaft connecting rod journals and the bearings (see section "Checking the technical condition" in the cylinder block of the G6BA engine).
14. Use a scraper to clean the top of the piston from carbon deposits. Push the piston together with the connecting rod out of the cylinder through the top.
Note:
- Do not disassemble the connecting rod, connecting rod cap and connecting rod bearings.
- Place the removed pistons with connecting rods in the order corresponding to the cylinder numbers for correct installation later.
15. Remove the front housing.
16. Loosen 5 bolts (B) and remove the rear oil seal housing.
17. Remove the main bearing caps and check the clearance between the crankshaft main journals and the liners (see section "Checking the technical condition" in the cylinder block of the G6BA engine).
18. Check the axial clearance of the crankshaft (see section "Checking the technical condition" in the cylinder block of the G6BA engine).
19. Carefully remove the crankshaft (A) from the cylinder block so as not to damage the main journals.
Note: Arrange the main and thrust bearing shells in the order for installation.
20. Check the suitability of the piston pin. To do this, try to move the piston relative to the pin. If relative movement is possible, it is necessary to replace the piston pin and piston as a set.
21. Using a special puller, remove the two compression rings. Manually remove the discs and the oil scraper ring expander.
Note: Arrange the piston rings strictly in the order corresponding to the cylinder numbers.
22. Disconnect the piston from the connecting rod.
