Apply marks to the connecting rods, crankshaft main bearing caps and the corresponding cylinders. Make sure that the connecting rod caps and crankshaft main bearing caps are marked.
Loosen the connecting rod bolt nuts and remove the connecting rod caps.
Remove the pistons with connecting rods through the cylinders.
Remove the connecting rod bearing shells and determine the degree of wear of the shells. If the shells can be used again, mark the shells to determine their position ("top", "bottom") and mark the corresponding connecting rods.
Loosen and remove the piston pin retaining rings using round-nose pliers and press out the pins using a mandrel.
Check the axial free play of the crankshaft.
Loosen the main bearing cap mounting bolts and remove the caps together with the lower bearing shells.
Remove the crankshaft from the bearing seats, and then the upper bearing shells.
The main bearing caps are marked with numbers 1-5, indicating the order in which they were installed during engine assembly. If the main bearing shells are to be reused, both the lower and upper shells must be marked.
