GT-15 – Rubber Flex Disc – Fiat Application – Bolt Circle Dia 61MM – Disc Width 14.5MM

GT-15 is a crucial component for Fiat vehicles, specifically designed to absorb torsional vibrations between the transmission output and driveshaft input. This flex disc features a bolt circle diameter of 61MM, a disc width of 14.5MM, and four bolt holes with a diameter of 8MM. This configuration allows it to effectively compensate for minor angular misalignments without the need for a universal joint, which is essential for maintaining smooth operation in the driveline.

Engineers selected these dimensions to ensure compatibility with various Fiat models while addressing the typical load cases encountered in light-duty applications. The GT-15 flex disc significantly reduces NVH (noise, vibration, harshness) within the cabin, providing a more comfortable driving experience. Failure symptoms such as clunking on takeoff or vibrations at low speeds can indicate a need for replacement, making it critical to monitor the condition of this part.

• Application: Fiat vehicles
• Bolt Circle Diameter: 61MM
• Disc Width: 14.5MM
• Bolt Hole Count: 4
• Bolt Hole Diameter: 8MM

When installing the GT-15, ensure proper bolt orientation and alignment according to the manufacturer’s specifications. Torque the bolts in a star pattern to avoid uneven stress on the flex disc. Regular inspections for cracks or deformation at the reinforcement sleeves can prevent unexpected failures and maintain optimal driveline performance.
