Tronair K-2965 – Outboard Roller Support Kit for Aircraft Wheel & Brake Dolly

The K-2965 Outboard Roller Support Kit is designed to extend the functionality of the Tronair Wheel & Brake Dolly by supporting the removal and installation of outboard wheels on larger aircraft, such as Gulfstream models. It allows technicians to safely handle heavier or more complex wheel assemblies by adding additional stability and roller support. This reduces strain during maintenance and ensures that the dolly can accommodate a wider range of aircraft operations.

The kit attaches directly to the dolly’s existing roller system, using external retaining rings, a roller tube assembly, and a support rod. This creates a wider roller configuration that supports larger wheels without compromising safety or ease of movement. By using simple hardware connections, the kit can be installed or removed quickly, allowing the dolly to adapt to different aircraft maintenance tasks.

The kit is particularly useful for business jets and heavy aircraft with wide landing gear, such as Gulfstream models. Outboard wheels on these aircraft can be challenging to maneuver without additional roller support. By stabilizing these assemblies, the K-2965 kit helps maintenance crews handle them more safely and efficiently, reducing the risk of accidents or component damage.

By adding roller stability and broader load distribution, the K-2965 reduces the risk of wheel assemblies tipping or shifting during removal and installation. This prevents potential injuries to ground crew and minimizes the chance of costly damage to the aircraft’s landing gear or brake components. The added support also ensures a smoother rolling motion when positioning wheels onto or off the aircraft.

Yes, the K-2965 is designed for straightforward installation on the Tronair Wheel & Brake Dolly. Technicians can attach it using simple tools, with minimal adjustments required. Because it uses the dolly’s existing design features, no complex modifications are needed, allowing crews to switch between standard and outboard configurations efficiently.

The roller support system allows the wheel or brake assembly to rotate freely as it is aligned with the aircraft hub. The outboard rollers help balance the weight, ensuring that large-diameter wheels don’t shift unexpectedly. This makes the mounting and removal process smoother, cutting down on manual force and reducing the time needed for service.

Routine maintenance involves inspecting the roller assembly, thumb screws, and support rod for wear or damage. Lubricating moving parts like roller bearings with multipurpose grease helps ensure smooth operation. Regular inspections should be conducted in line with Tronair’s dolly maintenance schedule to maintain reliability and safety.

The addition of the K-2965 does not increase the dolly’s maximum rated load of 700 lbs (318 kg). Instead, it redistributes support for outboard wheels, making handling safer within the dolly’s rated limits. Crews should always respect the original dolly specifications to avoid overloading and potential structural stress.

The K-2965 kit is covered under Tronair’s one-year warranty against material and manufacturing defects. Normal wear items and damage caused by misuse or unauthorized modifications are not included.

By reducing manual handling effort and providing a more stable platform for large aircraft wheels, the K-2965 helps maintenance crews complete wheel and brake servicing faster. The smoother roller action reduces downtime between wheel removal and installation, supporting faster aircraft turnaround. This efficiency is especially valuable in MRO facilities and flight departments managing tight service schedules.
