NISSAN 30501-VB000 Clutch Release Bearing Sleeve

This genuine NISSAN clutch release bearing sleeve (OEM part number: 30501-VB000) is a crucial structural component of the vehicle clutch system. Its function is to precisely guide and stably position the clutch release bearing on the transmission input shaft, ensuring smooth and consistent disengagement when depressing the clutch pedal.

Technical Features and Functions

• Premium Material Quality: Manufactured from high-strength, heat-treated steel alloy that withstands continuous mechanical stress and frictional heat loads.
• Precision Machining: Strict factory (OEM) tolerances guarantee a perfect fit with the release bearing and release fork, minimizing free play.
• Low-Friction Surface: The outer surface of the sleeve is engineered to allow unobstructed axial movement of the bearing, preventing binding or jerking.

Common Symptoms of Wear or Failure

Natural wear of the clutch release bearing sleeve or insufficient lubrication can lead to the following issues, indicating that the component needs replacement:

• Binding Clutch Pedal: If the sleeve surface becomes grooved, scored, or worn, the release bearing cannot slide smoothly, resulting in a stiff, heavy, or notchy pedal feel.
• Abnormal Noises: Metallic grinding, scraping, or squeaking sounds when pressing the clutch pedal.
• Difficult Gear Shifting: Imprecise or incomplete disengagement can make shifting gears stiffer or more difficult, which may cause long-term damage to internal transmission components.

When overhauling the clutch system or replacing the clutch release bearing, inspecting the clutch release bearing sleeve and replacing it as needed is highly recommended to ensure the reliable operation of the entire system.
