Detailed Description

The seal’s reinforced case and ribbed inner diameter help maintain a secure fit in the housing while the contamination exclusion system helps reduce debris intrusion that can lead to leakage. This part cross-references National 2443 and SKF 13527 for the same application.

  • Contamination entering the rear seal area
  • Seal wear from heat build-up around the lip
  • Minor shaft or spindle surface imperfections affecting sealing
  • Damage during seal installation

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation. Clean the sealing surface and inspect the output shaft for wear, scoring, or corrosion before pressing in the new seal. Confirm rear-position fitment for the specific Ford or Mercury model and transmission design before service. Timken 2443 is listed for rear applications on 1971-1987 Ford and Mercury vehicles, including Ford Mustang, Ford Bronco II, and Mercury Capri.
