1. Check the connecting rod bearing clearance with plastigage (see CONNECTING ROD BEARING REPLACEMENT  ).
2. Check the main bearing clearance with plastigage (see CONNECTING ROD AND CRANKSHAFT END PLAY INSPECTION  ).
3. Install the bearing halves in the engine block and the connecting rods.
4. Apply new engine oil to the main bearings and the rod bearings.
5. Install the crankshaft position (CKP) pulse plate (A) on the crankshaft (B); face the marked side (C) opposite the crankshaft, and align the tab (D) on the CKP pulse plate with the groove (E) on the crankshaft.
