Detailed Description

National 350936 is an engine crankshaft seal, also described as an oil seal, engineered around exact shaft and housing dimensions for proper sealing at the crankshaft. The nitrile material is selected for sealing service where oil exposure is a factor, while the 65.300 mm outside diameter and 7.920 mm width support accurate fitment in the housing bore. This part cross-references Gates 18562 and Continental 63145 for the same application.

For buyers servicing a Ford F-100, Ford F-250, or Ford F-350, this seal provides a fitment-specific replacement option for front crankshaft sealing. It also applies to many Ford passenger cars and Mercury and Edsel models from the 1950s and 1960s, making National 350936 a practical choice when matching the original seal dimensions matters.

What It Helps Address

• Oil leakage at the crankshaft seal area.
• Worn or hardened sealing material.
• Improper sealing from incorrect shaft or housing dimensions.
• Service needs on classic Ford, Mercury, and Edsel front crankshaft applications.
• Replacement of a deteriorated oil seal in the engine sealing system.

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the sealing surface and inspect the crankshaft for wear or scoring that could affect seal life. Confirm the application against the vehicle's original seal dimensions, especially on older Ford and Mercury models where production changes can affect fitment.
