    G07767761
    CAUTION:
    • Insert the SST between the oil pan and the ladder frame by tapping it with a plastic hammer in the direction of (1) arrow.
    • After tapping the SST with a plastic hammer along the direction of (2) 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 can result in damage of the SST.
  9. Remove the crankshaft damper pulley(A).
