Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation to confirm the WS1180 matches the original seal dimensions. Inspect the sealing surface for scoring or corrosion, and clean the bore thoroughly before pressing the new seal into place. For best results, install the seal squarely to avoid distortion and ensure even contact around the pinion shaft.
