This part cross-references National 450185 for the same application.

Key Features

  • Precision sealing design helps control oil and grease loss at the transfer case output shaft
  • Reinforced outer case resists installation damage and supports long-term durability
  • Ribbed rubber inner diameter helps seal minor spindle imperfections and promotes positive seating
  • Internal contamination exclusion system helps keep debris out of the seal area
  • Vent holes allow lubricant flow around the seal lip to reduce heat buildup

Detailed Description

Timken 450185 transfer case output shaft seal is engineered for vehicles that rely on a Spicer 20 or Spicer 21 transfer case. It is listed for 1966-1976 Ford Bronco, 1975-1976 Ford F-100, 1976 Ford F-150, 1975-1976 Ford F-250, 1969-1974 Ford E-100 Econoline, 1966-1973 Jeep CJ5, and 1965-1967 and 1972-1973 Jeep Wagoneer. The seal design focuses on keeping lubricant in place while helping prevent contamination that can lead to leakage and wear.

Common Problems This Seal Helps Address

  • Transfer case fluid seepage at the output shaft
  • Contamination entering the seal area from road debris
  • Leakage caused by minor shaft surface imperfections
  • Heat-related seal wear from poor lubricant circulation
  • Moisture and dirt intrusion around the transfer case output
