Detailed Description

National 710937 is an engine crankshaft seal designed around metric dimensions for front-mounted sealing applications. The seal measures 45.000 mm on the shaft side, 67.000 mm at the housing bore, and 8.000 mm in width, making it a precise replacement for engines that require controlled oil sealing at the crankshaft. National has supplied sealing products for decades, and this oil seal reflects that focus on fit and material selection. This part cross-references Mopar 68079589AA and MAHLE 67972 for the same application. It is a strong match for front crankshaft seal service on vehicles such as Chrysler 300, Dodge Charger, and Jeep Grand Cherokee, as well as other listed Chrysler, Dodge, Jeep, Ram, and Volkswagen models.

Common Problems This Seal Can Address

• Oil leakage at the front crankshaft area
• Visible oil residue around the timing cover or crankshaft snout
• Seal wear from age, heat, and engine contamination
• Loss of sealing integrity after crankshaft service
• Maintenance replacement during front engine teardown

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the correct metric fit. Inspect the crankshaft sealing surface for grooves, scoring, or contamination before pressing in the new seal. Clean the bore and surrounding area thoroughly, and install the seal squarely to avoid distortion. Confirm front-position fitment for the specific vehicle and engine configuration before assembly.
