Removing
1. Open the hood.
2. Remove the cylinder head.
3. Install motor mounting bracket.
4. Install motor mount.
5. Remove the oil pan.
6. Set the crankshaft to the top dead center position of the piston of the first cylinder.
7. Loosen and discard 4 connecting rod bolts (4) from the second and third cylinders,
8. Remove connecting rod caps (3) from the second and third cylinders.
Note.
- Tag connecting rod caps (2) for correct installation in the future.
- The connecting surfaces of the connecting rods and connecting rod caps are uniquely shaped for installation in the only possible position, so that the connecting rods and connecting rod caps are not allowed to fall. Do not process the parting surfaces.
9. Remove the lower connecting rod bearings (1).
Note. Arrange the removed parts in the order corresponding to the numbering of the cylinders.
10. Lower the car.
11. Push out two pistons with connecting rods (1) from the second and third cylinders through the top.
Note. Tag connecting rods (2) and arrange them in the order corresponding to the numbering of the cylinders.
Attention. Be careful not to damage the cylinder bore surface, piston rings and piston surfaces.
12. Remove the two upper connecting rod bearings (3) connecting rods of the second and third cylinders.
13. Rotate the crankshaft 180°to set the second cylinder piston to top dead center.
14. Raise the car.
15. Loosen and discard 4 connecting rod bolts (4) first and fourth cylinder.
Note
- Tag connecting rod caps (2) for correct installation in the future.
- The connecting surfaces of the connecting rods and connecting rod caps are uniquely shaped for installation in the only possible position, so that the connecting rods and connecting rod caps are not allowed to fall. Do not process the parting surfaces.
16. Remove connecting rod caps (3) first and fourth cylinders.
17. Remove the lower connecting rod bearings (1).
Note. Arrange the removed parts in the order corresponding to the numbering of the cylinders.
18. Lower the car.
19. Push out two pistons with connecting rods (1) from the second and third cylinders through the top.
Note. Tag connecting rods (2) and arrange them in the order corresponding to the numbering of the cylinders.
Attention. Be careful not to damage the cylinder bore surface, piston rings and piston surfaces.
20. Remove the two upper connecting rod bearings (3) connecting rods of the first and fourth cylinders.
Installation
1. Make sure that the piston ring locks are located according to the diagram shown in the figure (A, B, C).
Note. The arrow on the bottom of the piston is directed towards the drive of the gas distribution mechanism.
2. Lubricate the piston rings, pistons, cylinder bore and piston ring compressor with clean engine oil.
3. Install the piston ring compressor on the pistons.
4. Insert the upper connecting rod bearings (1) into the connecting rods and insert the pistons with the connecting rods as an assembly (1) into the first and fourth cylinders of the engine, guided by pre-applied marks (2).
Attention. Be careful not to damage the cylinder bore surface, piston rings and piston surfaces.
5. Raise the car.
6. Insert the lower connecting rod bearings (1) and install connecting rod caps (3) into the cylinders of the first and fourth cylinders.
Attention. Be careful not to scratch or damage the connecting rod bearings.
7. Install 4 new connecting rod bolts (4) and tighten in two steps:
- First step: tighten to 25 Nm.
- Step 2: Tighten with tool EN-45059 another 60°.
8. Rotate the crankshaft 180°and set the crankshaft to top dead center on the second cylinder.
9. Lower the car.
10. Insert the upper connecting rod bearings (1) into the connecting rods and insert the pistons with the connecting rods as an assembly (1) into the second and third cylinders of the engine, guided by pre-applied marks (2).
Attention. Be careful not to damage the cylinder bore surface, piston rings and piston surfaces.
11. Raise the car.
12. Insert the lower connecting rod bearings (1) and install connecting rod caps (3) into cylinders 2 and 3.
Attention. Be careful not to scratch or damage the connecting rod bearings.
13. Install 4 new connecting rod bolts (4) and tighten in two steps:
- First step: tighten to 25 Nm.
- Step 2: Tighten with tool EN-45059 another 60°.
14. Turn the crankshaft in the direction of normal rotation to the position of 60°to the top dead center of the piston of the first cylinder.
15. Install the oil pan.
16. Install fixture CH-49290, following the manufacturer's instructions.
17. Remove engine mount.
18. Remove motor mounting bracket.
19. Install the cylinder head.
