Installation Notes and Tips

Verify crankshaft journal size, housing bore, and oil clearance before assembly. Clean all rod and cap surfaces thoroughly, and confirm that the bearing shells seat fully before final torque procedures. Because this part is a standard-size bearing set, it should be matched to the engine’s measured dimensions rather than assumed from model year alone. Use the fitment list to confirm the exact vehicle and engine application before installation.
