    NOTE: Loosen one oil pan bolt near each corner of the oil pan leaving the bolts held in by about 2 threads. Then remove all other pan bolts.
    NOTE:
    • Insert the SST between the oil pan and the ladder frame by tapping it with a plastic hammer in the direction of arrow.
    • After tapping the SST with a plastic hammer along the direction of arrow around more than 2/3 edge of the oil pan, remove it from the ladder frame.
    • Do not turn over the SST abruptly without tapping. It is result in damage of the SST.
    • Be careful not to damage the contact surfaces of ladder frame and lower oil pan.
  18. Set the jack to the edge of ladder frame.
    NOTE: Put the wooden block between ladder frame and jack.
    CAUTION: Be careful not to damage the balance shaft & oil pump module.
  19. Disconnect the ground line (A), and then remove the engine mounting support bracket (B).
