Connecting Rod Bearings

  1. Always measure connecting rod bearing clearances 1 at a time. Use Plastigage method for measuring bearing clearances. Ensure oil film is removed from bearing halves and crankshaft journal prior to measuring clearance.
  2. With Plastigage in place, install bearing cap and tighten to specification. Do not allow crankshaft to turn. Remove bearing cap. Measure flattened width of Plastigage with scale furnished to determine clearance.
  3. Use a feeler gauge to check connecting rod side clearance. Insert feeler gauge between connecting rod and crankshaft thrust face.
