Turbine Shaft Seal Replacement

  1. Remove oil seal rings from turbine shaft. Inspect seal ring grooves for nicks or burrs. Lubricate each oil seal ring. Place Seal Protector/Installer Kit (J-38736) on turbine shaft.
  2. Quickly slide each seal into ring groove when protector is in position. Use seal driver from Kit (J-38736) to push ring over seal protector. Size seal with seal sizer from Kit (J-38736); gently twist seal sizer over each seal. Leave sizer in place.
