Aerospatiale SA 316/SA 319 Alouette III: Wheel and Brake Shop Service Tools

Wheel and brake shop service tools are used to maintain and repair aircraft landing gear systems, including wheels, brakes, and struts. They enable precise alignment, secure mounting, and efficient component handling during maintenance and repair. Proper use of these tools helps ensure aircraft safety, reliability, and regulatory compliance during ground operations.

Aircraft landing gear systems operate under high loads and pressures, requiring precision servicing to maintain performance and safety. Specialized tools, such as brake alignment and disc locator tools, allow technicians to perform maintenance accurately without damaging sensitive components. Using dedicated equipment ensures consistency, reduces human error, and supports compliance with OEM specifications.

Wheel and brake service equipment typically includes brake alignment tools, brake disc locator tools, landing gear service units, combo nitrogen/landing gear carts, strut servicing tools, and universal servicing devices. Each tool is designed for specific maintenance tasks, such as aligning brake assemblies, checking tire pressure, or recharging struts. Together, they form the foundation of any well-equipped aircraft maintenance facility.

Brake alignment tools ensure that the aircraft’s brake assemblies are correctly positioned relative to the wheel hub and disc. Proper alignment reduces uneven wear, enhances braking efficiency, and prevents vibration during operation. By maintaining OEM-specified alignment, these tools help extend the life of brake components and improve safety during aircraft ground handling.

A brake disc locator tool helps technicians position and center brake discs accurately during reassembly or maintenance. This precision reduces the risk of misalignment and uneven pad wear, ensuring smooth brake operation. It’s an essential tool for maintaining proper fitment and performance in aircraft braking systems.

Landing gear service units are designed to test, service, and maintain the hydraulic and pneumatic systems within an aircraft’s landing gear. They enable controlled inflation, extension, and pressure adjustments while ensuring system integrity. Regular use of these units helps detect leaks, verify performance, and maintain the landing gear’s operational readiness.

Combination nitrogen and landing gear service units allow technicians to perform multiple maintenance tasks with a single system. These portable units handle both nitrogen servicing and hydraulic testing, enhancing efficiency and reducing hangar space requirements. Their dual-purpose design makes them ideal for high-traffic MRO environments where versatility and reliability are key.

Strut servicing tools are used to maintain the hydraulic and pneumatic struts that absorb shock during landing and taxi operations. They allow technicians to safely inflate, deflate, and adjust strut pressure, maintaining optimal performance. Proper strut servicing ensures smoother landings, improved ride comfort, and extended component life.

Universal servicing tools are versatile devices designed to accommodate a wide range of aircraft types and configurations. They enable technicians to perform common maintenance tasks, such as brake bleeding, tire inflation, and strut charging, without requiring multiple specialized tools. This flexibility reduces costs and improves efficiency in multi-aircraft maintenance operations.

Using the correct wheel and brake service tools ensures precise handling of delicate components, minimizing the risk of scratches, leaks, or deformation. Tools designed for aviation applications are built to exact tolerances that prevent over-torquing or misalignment. This protection helps preserve the performance and safety of landing gear assemblies over time.

Most tools are designed for specific aircraft or component families, but many universal models can accommodate multiple makes and models. Always refer to the manufacturer’s specifications or consult a qualified technician before use. PJi’s aviation specialists can assist in selecting tools that best match your aircraft’s maintenance requirements.

Inspection and calibration intervals vary by tool type and usage frequency, but should generally follow the manufacturer's recommendations. Regular checks help ensure measurement accuracy, prevent malfunctions, and maintain compliance with MRO safety standards. Well-maintained tools lead to more efficient servicing and consistent aircraft performance.

Common signs include loose fittings, reduced measurement accuracy, corrosion, or fluid leaks. Tools that no longer meet calibration standards or show excessive wear should be replaced immediately. Keeping equipment in optimal condition ensures both technician safety and consistent service quality.

Nitrogen is preferred because it’s dry, inert, and stable under high pressure – ideal for maintaining consistent strut performance. It prevents moisture buildup that can corrode internal components or affect hydraulic function. Combo nitrogen and landing gear service units make it easy to regulate and replenish nitrogen safely during maintenance operations.

PJi’s knowledgeable aviation specialists can recommend the ideal tools for your maintenance requirements, from brake alignment kits to full-service landing gear units. They provide guidance on compatibility, safety, and maintenance best practices to help optimize your shop’s efficiency. Whether you’re outfitting a new facility or upgrading existing equipment, PJi delivers expert advice and dependable aviation-grade solutions.
