GAO-21 – Rubber Flex Disc – Opel Application – Bolt Circle Dia 96MM – Disc Width 30MM

GAO-21 is a critical component for Opel vehicles, specifically engineered to absorb torsional vibrations between the transmission output and driveshaft input. This Rubber Flex Disc plays a vital role in compensating for minor angular misalignment, eliminating the need for a universal joint in many applications. With a bolt circle diameter of 96MM and a disc width of 30MM, it is designed to fit seamlessly into various Opel models.

When installing the GAO-21, it’s essential to check the bolt orientation and alignment arrows to ensure proper fitment. The disc features six bolt holes, each with a diameter of 12MM, which must be torqued to specification in a star pattern to avoid uneven stress. Common failure symptoms include clunking on takeoff and vibrations at low speeds, often caused by visible cracking or deformation of the disc. Regular inspection is crucial for maintaining optimal performance.

• Opel Application
