QUESTIONS & ANSWERS
The KUNZ Small Bead Breaker uses a built-in ramp and a wheel trolley with dual rollers to guide the wheel into place. This setup ensures the wheel is stable and properly aligned before bead breaking begins, while also reducing technician strain and improving safety during servicing.
The press tools on the KUNZ Small Bead Breaker are adjusted using a positioning lever supported by a gas spring, allowing quick and smooth height changes without additional tools.
For precise alignment, the press arms can be tilted into the correct position, with a built-in pointer to guide adjustments. This combination makes it easy to match a wide range of tire sizes while ensuring accurate bead separation and preventing rim damage.
No, the SBB is designed to handle different tire sizes without adapter rings. This feature increases efficiency and allows for higher throughput in busy maintenance environments.
The KUNZ Small Bead Breaker uses an electrohydraulic system powered by foot pedals to activate the bead-breaking action. This hands-free operation allows technicians to stabilize the wheel while applying steady, controlled pressure for precise bead separation. The design improves efficiency and safety by ensuring both accuracy and ease of use during servicing.
If the bead needs additional breaking, the tire can be rotated quickly on the integrated rollers. This eliminates the need to reset or reposition the press tools, allowing for efficient, repeatable bead breaking with minimal downtime.
Yes, the SBB produces very low operational noise thanks to its specialized press tool design. Unlike some bead breakers, it does not generate loud “break” sounds during use, making it more comfortable for technicians and suitable for shop environments.
The press tools form a semi-circle with wide, rounded edges that gently press against the tire. This prevents damage to the tire or surrounding components, such as heat shields, ensuring safe and effective servicing.
No, the KUNZ Small Bead Breaker does not require yearly calibration. The unit is engineered with durable components and a reliable electrohydraulic system that maintains consistent performance without the need for frequent recalibration.
This makes it easier for maintenance teams to keep the equipment in service with minimal downtime while ensuring dependable bead-breaking results.
KUNZ recommends replacing the filter (part number 131.3025) once per year to maintain optimal performance. Regular filter changes help ensure clean hydraulic operation, protect the system from contaminants, and extend the service life of the bead breaker. Sticking to this preventative maintenance schedule keeps the equipment reliable and ready for demanding aircraft wheel service tasks.
