  1. Install the main bearings and lubricate with engine oil.
  2. Install the crankshaft on the journals.
  3. Notice: In order to prevent the possibility of cylinder block or crankshaft bearing cap damage, the crankshaft bearing caps are tapped into the cylinder block cavity using a brass, lead, or a leather mallet before the attaching bolts are installed. Do not use attaching bolts to pull the crankshaft bearing caps into the seats. Failure to use this process may damage a cylinder block or a bearing cap.

  4. Install the crankshaft caps. Tap gently into place with a suitable tool.
  5. Install the crankshaft cap bolts. Finger tighten.

  6. Object Number: 61859  Size: SH
  7. Seat the crankshaft thrust bearing.
  8. Tighten
    Tighten the bearing cap bolts to 20 N·m (15 lb ft), and rotate the bolts 90 degrees. Use the J 36660-A .

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
