Diagram Ref No 15

Constructed from high-grade hardened steel with precision-ground needle rollers, the bearing is designed to withstand continuous rotational movement, clutch loads and high operating temperatures inside the transmission housing. Its compact design provides maximum load-bearing capability while ensuring smooth clutch fork movement throughout the life of the clutch system.  

What This Product Does:

• Supports the clutch fork shaft within the transmission housing.
• Provides smooth, low-friction movement of the clutch fork.
• Reduces wear between the shaft and transmission casing.
• Maintains accurate clutch release mechanism alignment.
• Supports smooth clutch engagement and disengagement.
• Helps ensure consistent clutch pedal operation.
• Reduces friction and mechanical resistance within the clutch system.
• Forms an essential part of the clutch release mechanism.

Symptoms Of Wear Or Failure:

• Heavy or stiff clutch pedal operation.
• Squeaking, grinding or rattling noises when operating the clutch.
• Rough or inconsistent clutch engagement.
• Excessive play in the clutch fork shaft.
• Difficulty selecting gears.
• Premature wear of the clutch fork or shaft.
• Increased vibration through the clutch pedal.
• Bearing seizure or restricted clutch fork movement.
• Visible bearing wear during clutch servicing.
• Accelerated wear of surrounding clutch release components.

Why Replacement Matters:

• The clutch fork shaft needle bearing operates every time the clutch pedal is pressed and is subjected to repeated movement, mechanical loading, heat and vibration. Over time, lubrication can deteriorate, contaminants may enter the bearing and the needle rollers can wear, resulting in increased friction and reduced bearing performance.
• A worn needle bearing can cause stiff clutch operation, poor clutch feel and increased wear of the clutch fork, shaft and release mechanism. If left unresolved, excessive friction or bearing failure may lead to clutch release problems and more extensive transmission repairs.
• Replacing the clutch fork shaft needle bearing during clutch or gearbox servicing restores smooth clutch operation and helps protect surrounding drivetrain components. An OE Match replacement provides factory-style fitment, precision engineering and long-lasting durability, ensuring reliable clutch performance and maintaining the driving experience expected from your Porsche.
