REMOVE DRIVE PLATE AND RING GEAR SUB-ASSEMBLY
1. Using height adjustment attachments and plate lift attachments, place the engine assembly on a flat level surface.
  Note
  - Using height adjustment attachments and plate lift attachments, keep the engine assembly horizontal.
  - To prevent the oil pan sub-assembly from deforming, do not place any attachments under the oil pan sub-assembly of the engine assembly.
  - Using an engine sling device and engine lift, secure the engine assembly before service.
2. Using SST, hold the crankshaft pulley assembly.
