KUNZ 156.0000 RimPull Aircraft Wheel/Tire Assembly Tool

The RimPull replaces the need for excessive manual force by using a hydraulic pull action with a spring-assisted push return. This design allows technicians to bring wheel halves together safely and efficiently. By reducing physical strain, it not only improves ergonomics but also ensures more precise and controlled wheel assembly during aircraft maintenance.

The RimPull uses a single-acting hydraulic cylinder powered by a foot pump. When activated, the cylinder retracts the extension shaft to clamp the wheel hub securely, while a spring assists in returning the shaft to its starting position. This combination provides a reliable clamping force while simplifying operation for ground support crews.

The RimPull comes with two clamping discs that hold the wheel hub during assembly. One disc is fixed to the handle, while the other is detachable and can be mounted on the extension shaft from the opposite side of the wheel. Each disc features three adjustable set plates, allowing the tool to fit different wheel hub diameters across commercial and military aircraft.

For safe and effective use, the RimPull requires two operators. One technician inserts the extension shaft through the wheel hub, while the second attaches the free clamping disc on the other side. This collaborative process ensures the wheel is securely clamped and prevents misalignment during tightening.

The KUNZ RimPull is versatile enough to be used on both commercial and military aircraft wheels. Its adjustable clamping plates make it compatible with a wide range of wheel hub sizes, allowing MROs, airlines, and defense operators to standardize on one tool for multiple aircraft types.

Accurate wheel assembly is critical for safety, and the RimPull ensures hubs are properly aligned before bolts and nuts are installed. By providing a stable and controlled clamping method, it reduces the risk of cross-threading, uneven stress, or damage to the wheel components. This results in longer wheel life and safer aircraft operations.

The hydraulic clamping action significantly cuts down the time needed to assemble or disassemble aircraft wheels. Instead of relying on manual prying or less precise methods, technicians can complete the task quickly and with less effort. This efficiency translates into faster turnaround times for MRO facilities handling high volumes of wheel overhauls.

The RimPull is designed for durability, but like any hydraulic tool, it requires periodic checks. Operators should inspect the hydraulic cylinder for leaks, ensure the foot pump operates smoothly, and keep the clamping plates clean of debris. Regular care helps extend the tool’s service life and ensures reliable operation in demanding environments.

The RimPull is part of KUNZ’s integrated lineup of wheel shop equipment, which includes assembly stands, torque systems, and handling tools. By working seamlessly alongside other KUNZ solutions, it helps create a lean workflow that reduces technician effort and maximizes throughput in aircraft wheel and brake maintenance.

The KUNZ 156.0000 RimPull does not require standard spare parts or consumables for routine use, making it a low-maintenance tool for aircraft wheel assembly. However, replacement components may be available in the event of damage or excessive wear. Our support team is available to assist you in sourcing the correct parts to ensure your RimPull continues to perform reliably in demanding wheel shop environments.

No calibration is required for the KUNZ RimPull, as it is not a measuring device. The tool operates purely through a hydraulic pull-and-clamp system, which eliminates the need for periodic accuracy checks. Instead, users should focus on routine inspections for wear, hydraulic leaks, or damage to maintain safe and efficient performance during aircraft wheel and tire servicing.
