Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Inspect the camshaft surface for scoring, wear, or contamination, and clean the bore thoroughly so the seal seats evenly. Use proper installation tools to avoid distorting the lip or housing during assembly.

Confirm the seal orientation matches the engine application and check surrounding components for oil residue that could indicate a related leak source. For best results, compare the removed seal dimensions to the National 321417N specifications before final assembly.
