Detailed Description

Timken 472636 is a transfer case input shaft seal engineered for GM trucks and SUVs with New Process transfer case applications. It is a direct-fit sealing component for 1998-2007 Chevrolet and GMC models listed in the fitment data, including Chevrolet Avalanche, Chevrolet Blazer, Chevrolet S10, GMC Jimmy, and GMC Sonoma. This part cross-references Gates 22440 for the same application.

Timken’s seal design focuses on maintaining lubricant inside the transfer case while helping prevent dirt and other contaminants from entering the sealing area. The reinforced outer case adds strength during installation, and the ribbed inner diameter helps the seal conform to minor shaft surface imperfections for a more consistent seal. Timken 472636 is a practical replacement choice when servicing transfer case leaks on NP236, NP236C, and NP246-equipped vehicles.

Common Problems This Seal Can Address

• Transfer case fluid leaking from the input shaft area
• Contamination entering the transfer case through a worn seal
• Heat-related seal wear from poor lubricant circulation at the lip
• Seal leakage caused by minor shaft surface imperfections
• Service issues on NP236, NP236C, and NP246 transfer case applications

Installation Notes and Tips

Inspect the input shaft and seal bore before installation. Clean the sealing surface thoroughly and verify the transfer case application matches the vehicle and transfer case code listed in the fitment data. Proper seating is important for sealing performance, especially on GM 4x4 transfer case service jobs.

Quality Assurance

Timken oil and grease seals are built with precision sealing features intended to control lubricant loss and help keep contaminants out of the assembly.
