NISSAN 30537-0T000 Clutch Release Fork Pivot Ball Pin

The genuine OEM Nissan 30537-0T000 clutch release fork pivot ball pin (factory designation: PIN-BALL) is a critical precision component of the clutch system in manual transmission vehicles. This pivot pin provides a stable, low-friction fulcrum for the clutch release fork, which actuates the clutch release bearing when the clutch pedal is depressed.

Operating Principle and Importance

When operating the clutch pedal, the hydraulic or mechanical release system displaces the clutch fork. The fork pivots on this ball stud to deliver the necessary lever action. The precise geometry and hardened surface of the original Nissan pivot pin ensure that the clutch fork moves without unwanted play and with minimal friction, delivering smooth clutch modulation and precise shifting feel.

Common Symptoms of Wear and Failure

The clutch fork pivot pin is exposed to continuous mechanical loads and friction. Over time, due to loss of lubrication or natural wear, the following issues may arise:

• Squeaking or creaking noises: Mechanical noise when depressing the clutch pedal often indicates a dry or worn pivot pin.
• Stiff clutch pedal: If the spherical surface becomes scored or uneven, the fork cannot pivot smoothly, resulting in increased pedal effort.
• Sticking or notchy pedal action: Intermittent, uneven pedal travel during operation.
• Incomplete clutch disengagement: Severe wear or breakage alters the fork geometry, preventing the clutch from disengaging fully, which leads to hard gear engagement and potential transmission damage.

Technical Specifications

• Manufacturer: NISSAN (Genuine OEM part)
• Part Number: 30537-0T000
• Part Designation: Clutch Release Fork Pivot Ball Pin (PIN-BALL)
• Material: Specially heat-treated, high-strength steel alloy for maximum service life and minimal wear.
• Mounting Location: Inside the transmission bellhousing, at the clutch fork pivot mounting point.

When replacing the clutch pressure plate assembly or release bearing, inspecting and, if necessary, replacing the clutch fork pivot pin—along with applying an appropriate high-temperature grease—is strongly recommended to prevent premature component failure.
