Hayes Original Flywheel Couplings are used in petrol and tough diesel engine applications where torsional vibration occurs. Flexible neoprene elements absorb vibration and reduce shock loads, while providing a steady dampening effect.
Hayes couplings take up very little space while transmitting a surprising amount of torque. They’re available with a wide variety of spline and bores & keys that come ready to bolt to your flywheel. The splines do not lock onto the shaft in order to allow for any axial movement. This is similar to a drive shaft assembly in automotive applications.
All components have been designed for maximum life (when operated at normal engine speeds, torque, alignment, and appropriately serviced).
Design Characteristics:
Steel Yellow Zinc (Trivalent by 1-1-07) Flywheel Plate
- Sturdy, steel plate for continuous load support
- Yellow Zinc (Trivalent by 1-1-07) plating to protect against corrosive wear
Drive Hub:
- Precision machined for consistent quality
- Heat-treated splines to prevent premature shaft wear
- Two set screws for clamping bore and key applications
- Large driving surfaces for easy installation and longer drive life
- Splined and bore and key options for your specific applications
- Multiple hub lengths allow for easy installation in any standard SAE or non-standard application
Features and Advantages:
