NISSAN 31375-41X01 Output Shaft Oil Seal

The genuine NISSAN 31375-41X01 (Output shaft oil seal / SEAL-OIL) is a premium-quality, precision sealing unit that plays a vital role in ensuring a leak-free seal between the transmission and the drive shaft/output. This genuine OEM part guarantees a perfect fit and long service life, preventing gear oil leaks and protecting internal mechanical components from contaminants.

Key Features and Characteristics:

• Effective Lubricant Retention: Prevents transmission or differential oil from escaping past the output shaft.
• Protection Against Contaminants: The integrated dust lip keeps dust, water, and other road debris away from the sealing surface.
• Superior Material Quality: Made from high heat- and oil-resistant elastomer with a metal reinforcing ring and garter spring for stable and durable seating.
• Genuine (OEM) Quality: Manufactured to Nissan's strict factory standards, ensuring precise dimensional tolerances and dependable performance.

Technical Specifications:

• Part Type: Output shaft / axle shaft oil seal
• Material: High-resistance synthetic rubber (elastomer) with metal reinforcement
• Fitting Position: Transmission / differential output

Typical Signs of Failure:

• Oil spots or moisture appearing on the transmission casing at the axle/drive shaft connection.
• Dropping gear oil level, which can lead to shifting difficulties or accelerated gear wear.
• Increased accumulation of dust and dirt around the seal due to a leaking oil film.

Installation Tips:

When replacing the oil seal, it is recommended to thoroughly clean the shaft interface and inspect the shaft surface for signs of wear or scoring. Prior to pressing in the new seal ring, apply a thin coat of clean gear oil to the sealing lip to avoid initial dry running. Using a dedicated seal installation tool is recommended for a professional, damage-free installation.
