Piston, Connecting Rod, and Bearing Removal




1. Install the torsional vibration dampener bolt into the crankshaft and set pistons 1 and 4 to bottom dead center (BDC) in the direction of engine rotation.

Important: Note cylinder sequence.


2. Mark the connecting rod with the connecting rod bearing cover (1).




3. Unscrew pistons 1 and 4.

1. Remove the 2 connecting rod bearing caps (1).
2. Remove the 4 bolts.




4. Push the 2 pistons, with connecting rods, out of the cylinder bore.

Important: The shear surfaces of the connecting rod and the connecting rod bearing cover form a unique fit and must not be swapped or damaged. Do not lay down on the shear surfaces.


5. Remove pistons 1 and 4.
6. Turn the crankshaft on the torsional vibration balancer through 180 degrees in the direction of engine rotation.





Important: Note the cylinder sequence.


7. Mark the connecting rod with connecting rod bearing cover (1).




8. Unscrew pistons 2 and 3.

1. Remove the 2 connecting rod bearing caps (1).
2. Remove the 4 bolts.




9. Push the 2 pistons, with connecting rods, out of the cylinder bore.

Important:
* The shear surfaces of the connecting rod and the connecting rod bearing cover form a unique fit and must not be swapped or damaged. Do not lay down on the shear surfaces.

* Clean and visually inspect all components.


10. Remove pistons 2 and 3.





Important: Observe the correct fitting position and alignment.


11. Remove the connecting rod bearing mounting clips (1, 2).
12. Visually inspect the components.
