NISSAN 32113-VB000 Input Shaft Oil Seal

The genuine OEM Nissan 32113-VB000 input shaft oil seal (SEAL-OIL COVER) is a critical sealing component that ensures reliable retention of gear oil at the transmission input shaft. It prevents lubricant from entering the clutch bellhousing, thereby protecting the clutch assembly from contamination.

Key Features and Operating Principle

The input shaft oil seal is located directly on the transmission input shaft. Its function is to provide dynamic sealing between the rotating shaft and the stationary housing. Genuine Nissan parts are manufactured to strict tolerances, guaranteeing a perfect fit and long-term leak-free operation.

Technical Specifications

• Material Composition: High heat- and oil-resistant elastomer capable of withstanding modern synthetic gear oils and elevated operating temperatures.
• Design: Precision sealing lip with a tension spring to ensure constant and uniform radial clamping force.
• Factory Quality: Genuine Nissan OEM part ensuring reliability through dimensional precision and premium material quality.

Symptoms of Wear and Failure

Natural wear of the oil seal (aging, hardening) or mechanical damage can lead to the following issues:

• Oil Leakage: Transmission fluid accumulating at the bottom of the clutch bellhousing or along the engine-to-transmission mating surface.
• Clutch Slippage: Escaping oil reaching the clutch friction disc reduces friction, causing the clutch to slip and resulting in power loss.
• Low Gearbox Oil Level: Decreasing oil levels due to continuous leakage can cause premature wear and noisy operation of transmission gears and bearings.

When replacing the clutch or disassembling the gearbox, preventive replacement of the input shaft oil seal is strongly recommended, as labor costs to access this component are substantial.
