Note: The connecting rod and the connecting rod cap should have matching numbers at position (X). If necessary, make a temporary mark on connecting rod (1) and on connecting rod cap (5).
Rotate the crankshaft until the piston is at the bottom center position. Remove nuts (6) and remove connecting rod cap (5) from connecting rod (1).
Remove lower connecting rod bearing (4) from connecting rod cap (5).
Carefully push connecting rod (1) into the cylinder bore. Remove upper connecting rod bearing (3) from the connecting rod.
