    CAUTION:
    • Before and during lifting, always check if any harnesses are left connected.
  30. Remove the parts that may restrict installation of the engine to the engine stand.
    NOTE: This procedure is described assuming that you use an engine stand mounting to the surface to which the transmission mounts.
    1. Remove the drive plate.
      • Holding the crankshaft pulley bolt, lock the crankshaft to remove the drive plate bolts.
      • Loosen the bolts diagonally.
        CAUTION:
        • Be careful not to damage the drive plate. Especially avoid deforming and damaging of the signal plate teeth (circumference position).
        • Place the drive plate with the signal plate surface facing other than downward.

        • Keep magnetic materials away from the signal plate.
        CAUTION: Use an engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for supporting the engine weight.
      • If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the potential risk of overturning the stand.
      CAUTION: Before removing the hanging chains, make sure the engine stand is stable and there is no risk of overturning.
  31. Remove the alternator. Refer to "REMOVAL AND INSTALLATION ".
  32. Remove the engine mounting insulator and bracket using power tool.
