NISSAN 30514-01T0A Clutch Release Bearing Retaining Spring

The genuine NISSAN 30514-01T0A clutch release bearing retaining spring (factory designation: SPRING HOLDER) is a critical precision component in manual transmission clutch systems. This retaining spring ensures a stable, play-free connection between the clutch release bearing and the release fork, guaranteeing precise and reliable operation of the clutch assembly.

Technical Characteristics and Material Quality:

• Material Composition: High tensile strength, hardened spring steel that withstands continuous mechanical stress and high temperatures inside the transmission bell housing.
• Surface Treatment: Specialized anti-corrosion and anti-oxidation coating for enhanced durability.
• Function: Ensures constant and precise positioning of the clutch release bearing, preventing undesirable displacement or resonance.
• OEM Quality: Genuine Nissan part guaranteeing exact dimensional accuracy and tension force according to factory specifications.

Role and Symptoms of Failure:

During clutch actuation, the retaining spring is subjected to continuous mechanical stress. Over time, metal fatigue, corrosion, or physical wear can cause the spring to lose its tension or break. The most common symptoms of failure include:

• Abnormal metallic rattling or squeaking noises from the transmission area, especially when operating the clutch pedal.
• Uneven or one-sided wear on the release bearing, which may lead to premature clutch failure.
• Imprecise clutch feel or difficult gear shifting resulting from unstable guidance of the release fork.

When overhauling the clutch system or replacing the release bearing, replacing the retaining spring is strongly recommended to prevent subsequent failures.
