Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 100-384112-1 is a genuine OEM drive belt kit, containing a factory-matched set of two V-belts. This is a flight-critical component engineered specifically for driving the air conditioning compressor on the Beechcraft King Air 200 and 300 series of aircraft. These belts are designed to transmit mechanical power from the engine's accessory drive to the A/C compressor, a high-load application. Manufactured from a durable, reinforced synthetic rubber composite, this matched set is essential for ensuring proper system performance, preventing slippage, and achieving a long, reliable service life.

Key Features

• Factory-Matched Set: The single most critical feature is that these two belts are supplied as a factory-matched set. This ensures they are of identical length and construction, which is mandatory for any dual-belt drive system. A matched set guarantees that tension is distributed evenly across both belts, preventing premature wear and component failure.
• High-Strength, Reinforced Construction: Fabricated from a heavy-duty, synthetic rubber (elastomer) composite, reinforced with internal tensile cords. This construction is designed to resist stretching, cracking, and degradation from the high temperatures and oil exposure common in the engine nacelle.
• Precision V-Groove Profile: The V-shape of the belt is precisely molded to match the grooves in the engine and compressor pulleys. This ensures maximum surface area contact, providing a high-friction grip to transmit high torque loads without slipping.
• OEM Specification: As a genuine Textron Aviation part, this kit guarantees the correct belt length, V-angle, material composition, and tensioning characteristics required by the aircraft's original Type Certificate.
• Essential for System Performance: A properly tensioned, non-slipping belt set is essential for the air conditioning system to produce its rated cooling capacity. Slipping belts can lead to poor cooling performance and eventual system failure.

Technical Specifications

Aircraft Compatibility

The 100-384112-1 is the specified OEM A/C compressor drive belt set for some of the most successful and widely-used corporate and special mission turboprops in the world.

• Primary Aircraft Models:
  • Beechcraft King Air 200, B200
  • Beechcraft King Air 300
  • Beechcraft King Air 350 (B300)

Applications

The 100-384112-1 is a key component for maintaining the aircraft's environmental control system:

• Air Conditioning System Drive: The sole means of transmitting power from the running engine to the air conditioning compressor.
• Scheduled Maintenance: Drive belts are wear items and must be inspected regularly for cracking, glazing, contamination, and proper tension. They are replaced at specified intervals or when their condition warrants it.
• System Repair: A mandatory replacement item when replacing the air conditioning compressor or troubleshooting issues of inoperative A/C or slipping belts.

Why Choose 100-384112-1?

In a multi-belt drive system, using two individual, non-matched belts is a recipe for failure. Even a minuscule difference in length will cause the shorter belt to carry the majority of the load, leading to its rapid failure, while the longer belt will slip and glaze. The Textron Aviation 100-384112-1 kit eliminates this risk by providing two belts that have been manufactured in the same batch and measured to be virtually identical. This is the only way to ensure a balanced, reliable, and long-lasting drive system for a critical component like the air conditioner on a King Air.

The 100-384112-1 V-belt set transmits power through a wedging action. As the belt is tensioned, the "V" profile is pulled tightly into the corresponding V-groove in the pulleys. This creates a significant amplification of friction on the sides of the belt, allowing it to transmit much higher torque than a flat belt of the same tension. The use of a dual-belt system on the King Air's A/C compressor is an engineering choice to handle the high horsepower required to run the large-capacity compressor. The principle of using a matched set ensures that the load is shared equally, with both belts wedging into their respective grooves with the same force, which is essential for maximizing the life of the belts and the bearings in the engine drive pad and compressor clutch.

Note: This is a flight-critical accessory drive component. Installation must be performed by a certified A&P mechanic. Belts must be tensioned to the specific value in the aircraft maintenance manual using a belt tension gauge. Improper tension (either too loose or too tight) will lead to premature failure.
