69-134-945 - Barry Mounts 94011-20 Aircraft Engine Mount – Cessna, Commander, Piper, Mooney, Vans & More

No, the Barry Mounts 94011-20 aircraft engine mount does not include mounting bolts. These bolts are supplied by the aircraft manufacturer or OEM to ensure proper fit, torque specifications, and material compatibility for the specific engine and airframe application.

Always refer to your Aircraft Maintenance Manual (AMM) or manufacturer guidelines for the correct bolt size, grade, and torque values. Using the proper hardware is essential for safe installation and optimal vibration isolation performance.

The Barry Mounts 94011-20 engine mount is a vibration isolator designed to minimize the transmission of engine and propeller vibration to the airframe. It improves flight comfort, reduces pilot fatigue, and helps protect critical systems and structures from damage caused by repeated vibration. The mount's engineered materials and geometry provide shock absorption, stability, and long-term performance in demanding aviation environments. As part of a complete vibration isolation system, it enhances safety and extends the lifespan of both engine components and airframe structures.

The Barry Mounts 94011-20 is considered an equivalent replacement for the Lord J-9613-53 engine mount. Depending on the mounting configuration, the 94011-20 is also used in combination with the Lord J-9613-72HA isolator in some aircraft.

Yes! The Barry Mounts 94011-20 engine vibration isolator is FAA Parts Manufacturer Approval (PMA) certified. This means it meets strict aviation manufacturing and safety standards and is approved for use on eligible aircraft without additional certification. FAA-PMA approval helps simplify installation and ensures the isolator performs comparably to the original equipment.

Each Barry Mounts 94011-20 isolator assembly includes two molded rubber assemblies (one shimmed and one unshimmed), a spacer, and a washer. These components are engineered for proper pre-compression and positioning within the engine mount truss. The combination helps ensure vibration control while simplifying installation on supported aircraft platforms.

Yes, the 94011-20 is specifically designed and approved for installation without the use of a damper-bag center spacer. This streamlines the installation process and eliminates the need for additional internal mounting hardware. It also helps reduce weight while maintaining isolation performance and structural stability.

Hutchinson Aerospace recommends replacing the 94011-20 engine mount at every engine overhaul to ensure peak vibration isolation performance. Over time, engine mounts can degrade due to environmental exposure, heat, and repeated load cycles. Replacing them as part of regular overhaul practices helps maintain airframe integrity and flight comfort.

Yes, some aircraft applications require mixed isolator setups, such as combining two 94011-20 units with two 94011-02 isolators. These setups are determined by specific mounting positions and aircraft models. Always verify the correct combination using OEM documentation or FAA-PMA application sheets.

Most applications require four Barry Mounts 94011-20 mounts per engine, though some use only two in conjunction with other isolators. For twin-engine aircraft, the total number of required isolators per aircraft may be as high as eight. Refer to the FAA-PMA application chart or aircraft parts catalog to confirm the quantity needed for your platform.

The Barry Mounts 94011-20 is compatible with many Lycoming engine models, including the O-320, O-360, IO-360, TO-360, LO-360, and LIO-360 series. These engines are commonly found in aircraft like the Cessna 172, Piper PA-28 series, and other general aviation aircraft. Compatibility depends on the specific aircraft model and engine subtype, so it's essential to verify with the aircraft documentation.

The 94011-20 isolator is constructed from molded rubber compounds and corrosion-resistant hardware components. The rubber assemblies are engineered for vibration damping, temperature resilience, and long-term fatigue resistance. The included metal spacer and washer ensure proper installation alignment and pre-compression within the engine mount bracket.
