Inspect the shaft threads for damage or wear before installation to avoid cross-threading or stripping. If the threads are compromised, repair or replace the shaft assembly before installing part 3771005. Use a clean, dry workspace to prevent debris from entering the bearing housing during reassembly. Verify that the nut matches the specific thread pitch and diameter of your HX82 turbocharger model.
