Connecting Rod Bearing Service

  1. Remove rod caps after making sure caps are marked for cylinder identification. Use plastigage to check for proper clearance.
  2. Place plastigage across full width of bearing journal, parallel to crankshaft. Install rod cap and tighten nuts.
  3. Remove rod cap and determine amount of clearance by measuring width of compressed plastigage at widest point. Replace bearings having excessive clearance.
  4. Replacement bearings are available in standard .010" (.25 mm) and .020" (.50 mm) undersize.
  5. Coat bearing surfaces with oil. Install rod with bearing and tighten rod nuts.
  6. With all bearings checked and installed, tap each connecting rod forward and rearward along crankshaft to check for side clearance. Measure rod side clearance between connecting rod and side of crankpin.
