TOYOTA 31230-60201 Clutch Release Bearing Assembly

The TOYOTA 31230-60201 (alternative OEM part number: 3123060200) is a premium quality, genuine original equipment manufacturer (OEM) clutch release bearing assembly (BEARING ASSY, CLUTCH) that plays a vital role in the clutch system of manual transmission vehicles. This precision-engineered component provides the link between the clutch release fork and the clutch pressure plate assembly, enabling smooth disengagement and engagement of power transmission between the engine and the transmission.

Technical Specifications and Construction

The release bearing is engineered to withstand high rotational speeds, continuous friction, and thermal stress. Its sealed, factory-lubricated rolling bearing design minimizes internal friction and ensures maximum service life.

• Manufacturer: TOYOTA (Original Equipment Manufacturer)
• Part Number (SKU): 31230-60201
• OEM / Replacement Numbers: 3123060200
• Part Type: Clutch Release Bearing Assembly
• Material Quality: Heat-treated, high-wear-resistant alloy steel

Function and Operation

When the clutch pedal is depressed, the hydraulic or mechanical actuation system moves the clutch release fork, pressing the release bearing against the diaphragm spring of the clutch pressure plate. This applied pressure decouples the clutch friction disc from the flywheel, disconnecting engine torque from the transmission to allow smooth, safe gear shifting.

Typical Symptoms of Failure

As the release bearing is a rotating and dynamic wear part, it is subject to gradual mechanical wear over time. Typical signs of bearing failure include:

• Abnormal Noises: Humming, chirping, whining, or metallic grinding noises that occur specifically when the clutch pedal is pressed and disappear when the pedal is released.
• Pedal Vibration: Noticeable pulsation or vibration felt through the clutch pedal during actuation.
• Stiff Pedal Travel: Increased resistance or a rough, binding feel when depressing the clutch pedal.
• Difficult Gear Shifting: If the bearing binds or fails to fully depress the diaphragm spring, the clutch cannot fully disengage, leading to hard gear engagement.

It is recommended to replace the clutch release bearing simultaneously with the clutch pressure plate and clutch disc, as replacement requires transmission removal.
