Fitment Details

Compatible with 1965-1969 Porsche 911, N/A. This part cross-references Monroe Shocks & Struts (e.g., 111-307-113, 1458550189) for the same application.

For Porsche 911 manual transmission service, the SKF 550189 seal is sized to match the shaft and housing dimensions listed above. SKF has a long history in seal engineering, and this part reflects that focus with premium material selection and application-specific design for transmission use. If you are replacing a leaking input shaft seal on a 1965-1969 Porsche 911, this seal addresses the sealing interface at the transmission input shaft.

What It Helps Address

  • Transmission fluid seepage at the input shaft
  • Contamination entering the transmission housing
  • Seal wear from age, heat, and fluid exposure
  • Loss of sealing integrity during manual transmission service
  • Repeat leaks after prior seal replacement

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm proper seating in the transmission case. Inspect the input shaft surface for scoring or wear, and clean the sealing bore thoroughly before fitting the new seal. Use standard transmission service procedures and confirm the seal is installed squarely to avoid premature leakage.

Quality Assurance

SKF designs and manufactures seals to specific application requirements using premium materials and controlled production standards. The 550189 is engineered for long service life in transmission sealing applications and reflects SKF’s established seal development experience.
