Detailed Description

National 471651 is part of National’s 470000 series and is engineered as a camshaft seal for engine sealing applications where accurate dimensions matter. The seal’s 1.062-inch shaft diameter, 1.628-inch outside diameter, and 0.250-inch width help support a proper fit in the housing bore, while the nitrile material is selected for oil-sealing service. This part cross-references SKF 10598 for the same application.

• Repeat repairs from poor sealing contact

Installation Notes and Tips

Verify shaft, housing bore, and width measurements before installation to confirm the seal matches the engine application. Inspect the camshaft surface and surrounding sealing area for wear, scoring, or debris before fitting the new seal. Clean the bore thoroughly and install the seal evenly to avoid distortion. Confirm the vehicle application by year, make, and model before service; National 471651 is listed for Ford Escape and Mercury Mariner applications as well as several Ford, Mercury, Lincoln, Jaguar, and Mazda models.
