Detailed Description

This Timken transfer case selector shaft seal is engineered for applications where shaft sealing integrity matters. The design combines a reinforced outer case with a ribbed rubber inner diameter to help maintain a secure seal even when the spindle surface is not perfectly uniform.

This part number 6835S is listed for 1969-1974 Ford E-100 Econoline, 1963 Ford Thunderbird, and Chrysler applications including 1951-1955 Imperial, 1953-1954 New Yorker, 1952 Town & Country, and 1951 Newport with Eaton Pump notes.

Common Problems This Seal Addresses

• Gear oil seepage at the transfer case selector shaft
• Contamination entering the seal area through worn or exposed surfaces
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor spindle imperfections
• Reduced sealing performance during transfer case service on Ford and Chrysler Eaton Pump applications

Installation Notes and Tips

Inspect the shaft surface, bore, and surrounding housing before installation. Clean all sealing surfaces thoroughly and verify the seal is seated squarely to avoid edge damage. Use care during installation so the reinforced outer case is not distorted, and confirm the lip contacts the shaft evenly after assembly. For fitment verification, match Timken 6835S to the exact year, make, model, and Eaton Pump application listed for your vehicle.
