Detailed Product Overview

The FAG SR3507 is a transfer case output shaft repair sleeve engineered to provide additional sealing on worn or damaged shaft surfaces. Its stainless steel construction is heat treated for durability, and its dimensions are designed for a controlled installation on the shaft. Key measurements include a 1.891-inch shaft diameter, 2.205-inch flange diameter, 0.668-inch overall width, 0.551-inch width on shaft, and 0.984-inch installation depth. This part cross-references National 99189 and Timken KWK99189 for the same application.

Compatible vehicle coverage includes applications such as 2017-2020 Nissan Pathfinder, front; 2011-2017 Nissan Quest; 2000-2019 Nissan NV1500; and 2011-2016 Ram 1500, rear. The SR3507 also appears in a wide range of Nissan and INFINITI drivetrain service applications, making it a useful repair part when the sealing area on the shaft has been compromised. FAG SR3507 is a direct-fit repair sleeve solution for restoring the sealing surface without replacing the entire shaft assembly.

What It Helps Repair

• Oil leakage at a worn transfer case output shaft sealing surface
• Grooving or scoring on the shaft where the seal rides
• Premature seal wear caused by shaft surface damage
• Costly shaft replacement when the shaft can be repaired in place
• Service downtime from machining or full shaft removal

Installation Notes and Tips

• Clean the shaft thoroughly before installation so the sleeve seats evenly.
• Verify shaft diameter and installation depth against the listed dimensions before service.
• Install the sleeve squarely to avoid damaging the new sealing surface.
• Use the sleeve only on applications listed in the fitment data for proper coverage.
• Confirm transfer case position and vehicle configuration, especially on rear and front applications with notes.

Quality Assurance

FAG manufactures this repair sleeve as a precision sealing component for drivetrain service. The heat-treated stainless steel construction is intended to support long-term repair durability in applications where the shaft surface has already been damaged.
