Detailed Description
SKF 8620 is a transfer case shift shaft seal engineered around a 0.875-inch shaft diameter and a 1.129-inch outside diameter. The nitrile sealing surface is selected for sealing performance in drivetrain environments where lubricant control and contamination resistance matter. For owners servicing a Ford Mustang, Mercury Capri, or Chevrolet K20 Suburban transfer case, this seal supports a proper repair when the original seal shows wear or leakage.
SKF has a long history in seal design and manufacturing, and this part reflects that focus on dimensional accuracy and material selection. The 8620 is a practical replacement choice for transfer case sealing service on older Ford, Mercury, and Chevrolet applications.
Common Repair Symptoms
- Transfer case fluid leaking around the shift shaft
- Visible seepage or wetness at the seal area
- Contamination entering the transfer case through a worn seal
- Low lubricant level caused by seal wear
- Drivetrain noise or shifting concerns related to fluid loss
Installation Notes and Tips
Confirm shaft diameter and seal dimensions before installation. Clean the sealing bore and shaft surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing performance. Proper alignment during installation helps prevent premature wear and leakage.
Quality Assurance
SKF manufactures seals to specific designs using premium materials and controlled production standards. The 8620 is built to support long service life in transfer case applications while maintaining the sealing performance expected from an SKF drivetrain seal.
