1.6.	Remove the cutting debris from the cylinder and piston.





Important: Do not apply a stamping mark to any part of the connecting rod and piston assembly, A stamping mark on the side of the connecting rod, at the crankshaft journal, may affect component geometry.

2. Using a paint stick or etching tool, place match marks or numbers on the connecting rods and the connecting rod caps. The connecting rods and caps MUST be assembled to their original position and direction.
3. Mark the top of the piston to the specific cylinder bore.




Important: Mark, sort, or organise the connecting rod bearings so they may be installed to their original position and location. The connecting rods and the bearing caps are NOT interchangeable. Refer to Separating Parts.

4. Remove the connecting rod bolts (1).
5. Remove the connecting rod bearing cap (2).
6. Remove the connecting rod bearing (3).



7. Install the J 41556  (1) to the connecting rod.
8. Using a soft hammer, tap lightly on the end of the J 41556  (1) in order to remove the piston and connecting rod assembly from the cylinder bore.



9. Remove the piston and connecting rod assembly (2) from the cylinder block (1).
10. Upon removal of the piston and connecting rod assembly, assemble the connecting rod cap and bolt onto the matching connecting rod.
