4. Pull seal wear sleeve off shaft with puller.

5. Clean shaft surface removing all burrs from shaft where the wear sleeve gets installed.

6. Press new wear sleeve on to shaft. Oil heating new wear sleeve to 212°F approximately

aids in the installation of this ring.

7. Press new seal into housing with seal assembly tool, until contact with snapring.

8. Temporarily install new seal installation cone over shaft to protect seal during reinstallation.
