| ST 18252AA000 | CRANKSHAFT SOCKET |
(7) Push the #3 connecting rod in the direction of the arrow, and remove the #3 piston with #3 connecting rod from the cylinder block.
27. Set the cylinder block so that the oil pan side faces upward, and remove the mounting bolts attached to the locations shown in the figure.
28. Set the part so that the cylinder block RH is on the upper side, and separate the cylinder block.
CAUTION:
• Place a wood board wrapped with a waste cloth to prevent the knock pin damage and to stabilize the cylinder block before work.
• Be careful not to scratch the mating surface of cylinder block during work.
(1) Remove the bolt shown in the figure.
(2) Loosen the cylinder block mounting bolts in numerical order as shown in the figure, and separate the cylinder block RH and LH.
NOTE:
Lift the cylinder block RH slightly, and confirm that the crankshaft is remaining in the cylinder block LH. If the cylinder block RH is lifted carelessly when separating, the crankshaft may stick to cylinder block RH, then fall off.
29. Remove the crankshaft from cylinder block LH, and remove the rear oil seal.
