Key Features

Detailed Description

WS4901 is a manual transmission output shaft seal engineered for a secure, reliable seal at the shaft interface. The polyacrylate construction is selected for sealing performance, while the listed inside diameter, outside diameter, thickness, and housing bore dimensions support accurate application matching. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Use WS4901 when servicing Honda Civic, Honda Civic del Sol, Acura Integra, Honda CRX, Honda Odyssey, Acura EL, or Isuzu Oasis manual transmission applications that call for the specified seal dimensions and transmission codes. The seal helps maintain internal cleanliness and fluid retention in the transmission assembly.

What It Helps Solve

  • Transmission fluid seepage at the output shaft area.
  • Contamination from road debris and moisture entering the seal area.
  • Wear-related sealing loss in manual transmission service.
  • Incorrect seal sizing when replacing a worn output shaft seal.

Installation Notes and Tips

Verify the transmission code and side position before ordering, since fitment varies by model and application. Match the shaft diameter, housing bore, and seal width to the original part specifications for proper installation. Clean the sealing surface thoroughly and inspect the shaft for wear or scoring before installing the new seal.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and high-quality materials for dependable sealing performance in manual transmission service.
