Technical Notes

Piston rings seal the compressor or turbine wheel against the shaft to maintain rotational stability and prevent oil leakage. For HE351, HE431V, and HY40V units, verify the ring material and cross-section dimensions against your existing unit. Inspect the shaft for scoring or wear; replace the ring if the shaft diameter is out of specification. Ensure the ring gap is correct for the specific turbo model to avoid contact with the housing. This part is a replacement component; confirm the exact turbo configuration and engine application before installation.
