  2. Install crankshaft in block. Install main bearing caps in original location with arrow toward front of engine.
    CAUTION: Ensure proper type bearing is installed. All upper bearings have oil grooves EXCEPT No. 3 (center) bearing. All lower bearings do not have oil grooves. Install main bearing cap in original location with arrow facing toward front of engine.
  3. Check oil clearance using Plastigage method. Tighten bolts to specification. Remove main bearing caps. Clearance must be within specification. If oil clearance exceeds specification, replace bearings or crankshaft.
