Connecting Rod Bearings

NOTE: Following procedures are performed with oil pan and oil pump removed. Remove oil film from surfaces to be checked.
  1. Ensure rod caps are marked for cylinder identification. Remove rod cap and bearings. Inspect bearings for wear or damage and replace as necessary.
  2. Check crankshaft rod bearing journal for out-of-round or taper. Crankshaft out-of-round or taper must not exceed .001" (.03 mm).
  3. Check rod bearing clearance using the Plastigage method. If clearance exceeds specifications, undersize bearings may be used in combination to produce correct clearance. If clearance is still excessive, crankshaft must be reconditioned.
  4. Clean crankshaft journal and bearing surface in rod. Insert bearings in rod and cap, then lubricate bearing surfaces with oil. Pull piston and rod assembly down onto crankshaft. Install and tighten rod cap.
