What It Helps Address

• Engine oil seepage at the crankshaft seal area
• Grease or lubricant loss from the sealing surface
• Debris intrusion around the crankshaft opening
• Seal wear caused by heat build-up
• Minor sealing issues from shaft surface imperfections

Installation Notes and Tips

Confirm shaft diameter, housing bore, width, and helix direction before installation. Clean the sealing surface thoroughly and inspect the crankshaft for wear, scoring, or contamination before pressing the seal into place. Proper alignment during installation helps prevent lip damage and supports a uniform seal.
