Detailed Description

SKF 11138 is a PTO shaft seal designed to help maintain proper lubrication at the shaft opening while limiting the entry of dirt, moisture, and other contaminants. SKF has a long history in shaft seal engineering, and this seal is manufactured to defined dimensions and material requirements for the application environment. For buyers searching for an SKF 11138 PTO shaft seal, PTO shaft seal 1.125 shaft diameter, or driveline and axle gasket and sealing system parts, this component is built around the listed dimensions and nitrile sealing surface type. It is also a relevant replacement choice for service work on Ford and Chevrolet driveline-related applications where the correct PTO seal dimensions are required.

This part cross-references Davico Mfg 18427 for the same application.

What It Helps Address

• Gear oil or lubricant seepage at the PTO shaft opening
• Contamination entering the driveline sealing area
• Wear-related sealing loss at the shaft interface
• Improper sealing from a damaged or hardened old seal
• Service replacement needs for driveline and axle sealing systems

Installation Notes and Tips

Verify the shaft diameter, outside diameter, and seal width before installation to confirm the SKF 11138 matches the housing and shaft dimensions. Inspect the shaft surface for scoring or corrosion, since seal performance depends on a clean, smooth contact area. During installation, keep the sealing lip aligned squarely to avoid distortion, and lubricate the sealing surface with the correct fluid before startup. Confirm the PTO shaft seal seats fully in the bore before returning the vehicle to service.

Quality Assurance

SKF designs and manufactures seals to defined quality standards using premium materials selected for the application and operating environment. The result is a PTO shaft seal engineered for long service life and dependable sealing performance in driveline use.
