SKF 19554 Transfer Case Input Shaft Seal

SKF 19554 Transfer Case Input Shaft Seal

SKF 19554 is a transfer case input shaft seal built for controlled sealing at the shaft interface. With a nitrile sealing surface and precise dimensions, it helps maintain lubricant retention while keeping dirt and moisture out of the transfer case.

• Transfer case input shaft seal for drivetrain sealing service
• Nitrile sealing surface for reliable contact at the shaft
• Width: 0.472 in.
• Outside diameter: 2.843 in.
• Shaft diameter: 1.969 in.
• Direct fit for select 2001-2004 Nissan Frontier and 2001-2004 Nissan Xterra applications

Application Details

Compatible with 2001-2004 Nissan Frontier and 2001-2004 Nissan Xterra transfer case service, SKF 19554 is sized for the input shaft sealing location. The listed shaft diameter, outside diameter, and width help confirm proper fit during transfer case repair or reseal work. This part cross-references Nissan 3311101J00 for the same application.

Common Uses

• Stops transfer case fluid seepage at the input shaft
• Helps reduce contamination from road debris, water, and dust
• Addresses wet housing areas around the transfer case seal bore
• Supports repair of driveline leaks on Nissan Frontier and Nissan Xterra
• Restores sealing performance after seal wear or hardening

Installation Notes

Verify shaft diameter, outside diameter, and seal width before installation. Inspect the input shaft surface for scoring or wear, and clean the seal bore thoroughly before pressing the seal into place. Proper alignment during installation helps the nitrile sealing lip seat evenly on the shaft.

Quality Assurance

SKF has a long history in seal engineering, including early development of integrated shaft seals and continued refinement of bonding methods and material selection. SKF 19554 is manufactured to strict quality standards for consistent sealing performance and long service life.
