Connecting Rod Bearing Selection

Each connecting rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.0009 in.), in 0.006 mm (0.0002 in.) increments) depending on the size of its big end bore.

It's then stamped with a number or bar (1,2,3, or 4/I, II, III, or Nil) indicating the range. You may find any combination of 1,2,3, or 4/I, II, III, or Mil in any engine.

Normal Bore Size: 58.0 mm (2.28 in.)

Inspect the connecting rod for cracks and heat damage.

Connecting Rod Journal Code Locations

Numbers or bars have been stamped on the side of each connecting rod as a code for the size of the big end. Use them, and the letters or bars stamped on the crank (codes for rod journal size), to choose the correct bearings. If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.

  1. Remove the engine/transmission (see «ENGINE REMOVAL»(ref-336475-S14114366872009072700000) ).
  2. Remove the transmission (see «TRANSMISSION REMOVAL»(ref-371294-S15774378962010090700000) ).
  3. Remove the drive plate (see «DRIVE PLATE REMOVAL AND INSTALLATION»(ref-371294-S20353774152010090700000) ).
  4. Remove the cylinder heads (see «CYLINDER HEAD REMOVAL»(ref-336467-S18080966082009072700000) ).
  5. Remove the CKP sensor (see «CKP SENSOR REPLACEMENT»(ref-336453-S18438886572009072700000) ).
  6. Remove the timing belt drive pulley from the crankshaft (see «TIMING BELT DRIVE PULLEY REPLACEMENT»(ref-336467-S00977594722009072700000) ).
  7. Remove the oil pan (see «OIL PAN REMOVAL»(ref-336483-S01993479052009072700000) ).
  8. Remove the engine block end cover.
  9. Remove the rocker arm oil control solenoid/oil filter assembly.
  10. Remove the oil screen (A), the baffle plate (B), and the oil pump (C).
  11. If you can feel a ridge of metal or hard carbon around the top of any cylinder, remove it with a ridge reamer (A). Follow the reamer manufacturer's instructions. If the ridge is not removed, it may damage the piston as it's pushed out.
  12. Remove the connecting rod caps after setting the crank pin at bottom dead center (BDC) for each cylinder. Remove the piston/connecting rod assembly by pushing on the connecting rod. Take care not to damage the oil jets, the crank pin, or the cylinder with the connecting rod.
  13. Remove the bearing from the cap. Keep all caps/bearings in order.
  14. Remove the upper bearing halves from the connecting rods, and set them aside with their respective caps.
  15. After-removing a piston/connecting rod assembly, reinstall the cap on the rod.
  16. To avoid confusion during reassembly, mark each piston/connecting rod assembly with its cylinder number.
  17. Loosen the bearing cap bolts and the bearing cap side bolts in sequence 1/3 turn at a time; repeat the sequence until all bolts are loosened.
  18. Remove the bearing cap bolts (A) and the bearing cap side bolts (B), then remove the bearing caps (C).
  19. Lift the crankshaft (A) out of the engine block, being careful not to damage the journals and the CKP pulse plate.
  20. Remove the CKP pulse plate from the crankshaft (see «CKP PULSE PLATE REPLACEMENT»(ref-336483-S28379431922009072700000) ).
  21. Reinstall the main caps and the bearings on the engine block in the proper order.
