40-07700 – Cleveland Wheels & Brakes Nose Wheel Assembly
Available now through the AirParts Aero marketplace.
Overview Section
The Cleveland 40-07700 is a high-performance, 6-inch Nose Wheel Assembly manufactured by Parker Hannifin’s Cleveland Wheels & Brakes division. This assembly is a staple of the General Aviation (GA) industry, serving as the primary nose gear component for a wide array of high-performance single-engine and light-twin aircraft.
Engineered for durability and weight efficiency, the 40-07700 utilizes a split-rim design machined from high-strength aluminum alloy. This allows for easier tire mounting and maintenance while providing the structural integrity required for the high-impact cycles of takeoff and landing. The assembly is designed to accommodate a standard 6.00-6 aircraft tire and is recognized for its superior bearing life and corrosion resistance.
Key Features Section
High-Strength Aluminum Construction: Machined from aerospace-grade aluminum and finished with a protective anodized coating to resist salt, moisture, and chemical exposure.
Split-Hub Design: Features a two-piece rim held together by high-tensile through-bolts, facilitating simple tire and tube changes without the need for specialized heavy machinery.
Precision Tapered Roller Bearings: Equipped with high-load capacity bearings that ensure smooth rotation and reduce friction during high-speed taxi and landing rolls.
Dynamic Balance: Precision-engineered to minimize vibration, protecting the nose gear strut and sensitive avionics from harmonic oscillation.
FAA-TSO Certified: Manufactured under strict FAA Technical Standard Order requirements, ensuring the assembly meets or exceeds the mechanical stress limits of its airframe applications.
Standard 6.00-6 Fitment: Optimized for the industry’s most common nose tire size, ensuring a wide range of tire brand compatibility (e.g., Goodyear, Michelin, Air Trac).

Aircraft Compatibility Section
The 40-07700 is one of the most versatile nose wheels in the AirParts Aero inventory, commonly found on:
Cessna Series: Extensive use on the Cessna 172 (Skyhawk), 182 (Skylane), and 206 (Stationair).
Piper Aircraft: Found on many PA-28 Cherokee and PA-32 Saratoga variants.
Beechcraft: Compatible with certain Bonanza and Baron nose gear configurations.
Experimental/LSA: A premium choice for high-end kit-built aircraft like the Vans RV series (RV-10).
Technical Applications & Safety
In the landing gear ecosystem, the nose wheel is subject to unique stresses, including high-speed "shimmies" and side-loading during crosswind landings. The Cleveland 40-07700 is designed with a specific "offset" and "bearing spacing" to provide a stable pivot point.
Safety Warning: Proper maintenance of the through-bolts is vital. These bolts should never be tightened while the tire is inflated. Always deflate the tire completely before loosening the split-rim bolts to prevent an explosive decompression of the wheel halves.
The engineering excellence of the Cleveland 40-07700 is found in its Heat Dissipation and Bearing Geometry. Unlike generic hubs, the 40-07700 uses a specific alloy mix that effectively draws heat away from the tire bead and bearing races, extending the life of the rubber and the lubricant.
The bearing cups are "press-fit" into the wheel halves with high precision to prevent bearing race spin, a common failure mode in lower-quality wheels that leads to axle damage. The split-rim bolts are engineered with a specific "grip length" to ensure that the shear loads of landing are carried by the shank of the bolt, not the threads. Choosing the 40-07700 through AirParts Aero ensures your aircraft maintains its original Type Certificate standards, providing the mechanical reliability needed for thousands of trouble-free landings.
Installation & Maintenance Addendum
Bearing Lubrication: Use only high-temp aircraft wheel bearing grease (e.g., AeroShell Grease 22 or Mobil SHC 100).
Bolt Torque: Always use a calibrated torque wrench to tighten the through-bolts to the values specified in the Cleveland Maintenance Manual.
Inflation: Only inflate the tire once the wheel halves are fully bolted and torqued. Use a cage for safety during the initial inflation.
