GD-64 – Rubber Flex Disc – Bmw Application – Bolt Circle Dia 96MM – Disc Width 30MM

GD-64 is your go-to rubber flex disc for various BMW models, including the 5ER, 6ER, 7ER, M535, and Z4. This component plays a crucial role in absorbing torsional vibrations between the transmission output and driveshaft input, enhancing overall drivetrain performance. With a bolt circle diameter of 96MM and a disc width of 30MM, it’s engineered to handle minor angular misalignments without the need for a universal joint.

Before installation, ensure you check the bolt hole count of 6 and the bolt hole diameter of 12MM. Proper alignment is key; look for any orientation arrows on the disc to guide you. When tightening, use a star pattern to torque the bolts to specification, which helps distribute stress evenly across the flex disc. This attention to detail will prevent premature failure and ensure a smooth driving experience.

• Application: Fits BMW models including 5ER, 6ER, 7ER, M535, Z4
• Critical dimensions: 96MM bolt circle, 12MM bolt hole diameter
• Disc width: 30MM for optimal performance
• Installation tip: Check for cracks at reinforcement sleeves before installation
• Common failure symptoms: Clunking on takeoff, vibrations at low speed

By addressing these points, you’ll maximize the lifespan of the GD-64 flex disc and maintain the integrity of your BMW’s driveline. Remember, a well-installed flex disc not only reduces NVH but also contributes to a more enjoyable driving experience.
