Detailed Description
WS203006 is a differential pinion seal engineered as a direct sealing component for applications that require a 1.812-inch inside diameter, 2.566-inch outside diameter, and 0.5-inch width. The nitrile sealing material is selected for durability and consistent contact at the shaft and housing bore interface. This makes the seal suitable for restoring barrier performance where leaks, dirt intrusion, or moisture exposure have affected the differential assembly. Fits 1971-1973 International 1010, front inner; Fits 1972-1973 International 1110, front inner; Fits 1968-1972 International M1100, front inner; Fits 1958-1960 Lincoln Continental, front inner; Fits 1958-1960 Lincoln Premier, front inner. The WS203006 is also a practical match for additional International and Lincoln front inner listings in the fitment table.
Common Uses
- Stopping differential fluid seepage at the pinion seal area.
- Replacing a worn seal that allows road debris or moisture into the assembly.
- Restoring sealing integrity after age-related hardening or wear.
- Addressing contamination concerns in the differential housing.
Installation Notes
Verify shaft diameter and housing bore dimensions before installation to confirm the seal matches the application. Clean the sealing surfaces thoroughly and inspect the mating components for wear, scoring, or corrosion before assembly. Use the listed fitment data to confirm the correct International or Lincoln application before ordering.
Quality Assurance
InMotion manufactures this seal with precision-focused construction and high-quality materials to support reliable sealing performance in differential service.
