Detailed Description

The FAG SR3506 is an engine timing cover repair sleeve engineered to create a new sealing surface where the original shaft has been scored, worn, or damaged. Its precision fit and stainless steel construction make it a practical solution for sealing repairs on a wide range of Ford, Lincoln, Dodge, Jeep, Chevrolet, GMC, Mazda, and related applications. This part cross-references National 99187 and Timken KWK99187 for the same application. The SR3506 is commonly searched for timing cover seal repair on vehicles such as the Ford F-150, Ford Mustang, and Jeep Grand Cherokee, especially when a worn shaft surface is causing leakage at the seal contact area.

Key dimensions include a 1.875-inch shaft diameter, 2.203-inch flange diameter, 0.563-inch shaft width, 0.688-inch overall width, and 1-inch installation depth. These measurements are important when matching the sleeve to the shaft and seal location during repair work. The FAG SR3506 is also referenced under global number 413 3506 100.

Common Repair Uses

• Oil leakage at the timing cover seal surface
• Grooved or worn shaft sealing area
• Premature seal wear caused by surface damage
• Need for repair without replacing the shaft
• Costly machining or component replacement on service repairs

Installation Notes and Tips

Clean the shaft thoroughly before installation and inspect the sealing area for scoring or corrosion. Verify the shaft diameter and sleeve dimensions before pressing the sleeve into place. Because no machining is required, installation is typically faster than a full shaft repair, but the sealing surface must be prepared correctly for proper fitment. Confirm application details for your vehicle, including notes such as front, rear, or transfer case position where listed.

Quality Assurance

FAG manufactures this repair sleeve as a precision sealing component using heat-treated stainless steel for consistent repair performance. The SR3506 is built to restore the sealing surface on damaged shafts and support long-term service life in engine timing cover repair applications.
