Tronair 14B6801-0120 Aircraft Tire Bead Breaker with High-Pressure Pneumatic Pump

The Tronair 14B6801-0120 is designed to safely break tire beads from aircraft wheel rims during tire removal and installation. It is commonly used in aircraft maintenance environments where controlled, even force is required to separate the tire bead without damaging the wheel assembly. The unit also helps reduce tire sidewall height during wheel assembly. This makes it a versatile tool for both disassembly and reassembly procedures.

The 14B6801-0120 requires a shop air supply capable of delivering at least 90 PSI to operate the air-driven hydraulic pump. No external electrical power is required. The pneumatic foot switch controls hydraulic pressure during operation, enabling hands-free and controlled bead breaking. Proper air supply is essential for safe and effective performance.

The hydraulic system uses MIL-H-5606 aviation hydraulic fluid, as specified by Tronair. Maintaining the correct fluid type and level is crucial for the proper operation of the system. Using non-approved hydraulic fluids can affect performance and may void warranty coverage. The fluid level should be checked periodically before use.

This bead breaker supports wheel rim diameters ranging from approximately 8” up to 20” outside diameter. Proper operation requires selecting the correct breaker ring size based on the wheel’s outside diameter. Breaker rings must be matched to the specific application. The unit cannot function without an appropriate breaker ring installed.

No, breaker rings are not included with the Tronair 14B6801-0120 and must be purchased separately. PJi offers a range of Tronair breaker rings sized to match different wheel diameters, including options for wheels with or without chines. Selecting the correct ring is essential to ensure safe bead separation and prevent wheel damage. Our aviation specialists can help you choose the right-sized rings for your specific wheels.

Yes, the 14B6801-0120 is suitable for bolted split wheel assemblies and Goodyear demountable flange wheels. The unit is specifically noted for use on forged aluminum wheels commonly found on certain business and military aircraft. Proper setup and pad placement vary depending on wheel type. Always follow the wheel manufacturer's instructions during operation.

The tire must be completely deflated and the valve core removed before attempting to break the bead. Operators should ensure the wheel is properly centered and supported on the bead breaker before applying pressure. Hands and body parts should be kept clear of moving components during operation. Following all warnings and cautions in the Tronair manual helps prevent injury and equipment damage.

The “B” designation in the 14B6801-0120 indicates the air-assist (air-powered hydraulic pump) option. The 14-6801-0120 is the non-air-assist version of the same bead breaker design. While both units perform the same basic function, the air-assisted model reduces manual effort and improves workflow efficiency. In most cases, either unit can be used, depending on the shop's preference and the available air supply.

Routine maintenance consists primarily of visual inspections and checking the hydraulic fluid level. Operators should inspect pads, pins, hoses, and structural components for wear or damage. Maintaining clean hydraulic fluid and proper air connections helps ensure consistent performance. Replacement parts and seal kits are available if servicing is required.

Yes! PJi provides OEM replacement parts and service kits for the 14B6801-0120. Using genuine Tronair replacement parts is required to maintain warranty coverage. Replacement components include hydraulic seals, support pads, wheels, pins, and air pump assemblies. When ordering, please provide the model and serial numbers of your unit to verify parts compatibility.

The rugged welded steel construction makes the unit well-suited for hangar maintenance operations. While it is not a lightweight portable tool, its durability and stability make it ideal for repeated use in tire shops and maintenance facilities. Telescoping legs enable adjustment to accommodate various wheel widths. The pneumatic operation also reduces operator fatigue during frequent tire changes.

Yes! Proper setup is critical to protecting wheel assemblies during bead breaking. The unit includes padded support pads designed to distribute load and prevent metal-to-metal contact. Selecting the correct breaker ring size and ensuring adequate clearance between components helps avoid rim damage. Following Tronair’s setup instructions ensures safe and controlled operation.
