Technical Notes

For HE351, HE431V, and HY40V turbochargers, inspect the turbine wheel shaft diameter and material condition before installing this piston ring. Check for scoring or wear that may affect ring seating. Examine the bearing housing oil feed and return ports for blockages or debris to ensure proper lubrication during reassembly. If the old unit shows signs of foreign object damage, such as debris in oil passages or the turbine housing, perform a system clean before installation. This prevents contaminants from damaging the new piston ring and bearings. Verify all dimensions against your specific turbo configuration to ensure correct fitment.
