MC0523557-1 - McFarlane PMA Fuel Sender


PMA Replacement Part for 0523557-1


Fits: Cessna 172


Product Brief

The MC0523557-1 is a high-quality fuel quantity transmitter manufactured by McFarlane Aviation Products, designed as a direct replacement for the early style Stewart Warner Fuel Quantity Transmitter. This unit is compatible with the original fuel quantity gauges and wiring used in many Cessna aircraft, ensuring seamless integration and reliable performance.

Features and Benefits

  1. Direct Replacement: The MC0523557-1 is specifically engineered to replace the original fuel quantity transmitter installed by Cessna, saving you significant labor costs by eliminating the need to replace gauges and wiring when not required.
  2. Advanced Resistor Technology: Utilizing Stewart Warner’s thick film ceramic resistor technology, this transmitter offers enhanced durability and precision. The resistor is laser-trimmed to achieve consistent resistance, leading to longer life and improved accuracy.
  3. Viton Gaskets: Included in the kits, these gaskets are made from Dupont Viton, known for its superior flexibility and fuel resistance across a wide temperature range. Unlike cork or other elastomers, Viton gaskets do not dry out, shrink, or harden over time, ensuring a long-lasting, reliable seal.
  4. Screw-Seal Assemblies: The stainless steel hex drive screws included in the assemblies prevent corrosion and facilitate easy installation and removal. These screws come with Viton seals, offering a modern, effective solution to prevent leaks, unlike the original cork or rubber washers.

Installation and Compatibility

  • Easy Installation: The MC0523557-1 is designed for straightforward installation, significantly reducing downtime and maintenance costs. The hex drive screws minimize the need for excessive pressure during installation, preventing potential damage.
  • Compatibility: These transmitters are intended for use with Stewart Warner systems only. Using them as replacements for Rochester transmitters will result in incorrect fuel quantity readings. It is crucial to verify your aircraft’s current system before installation.

Applications

  • Aircraft Models: This fuel quantity transmitter is suitable for various Cessna models, maintaining compatibility with the original gauges and wiring. It is particularly beneficial for aircraft that have not been modified with the Cessna Service Kit for the Rochester system.

Important Note

Always ensure compatibility by checking your aircraft's specific make and model before installation. The MC0523557-1 is designed to replace Stewart Warner transmitters only and should not be used as a substitute for Rochester systems to avoid erroneous fuel readings.

By choosing the MC0523557-1 fuel quantity transmitter, you benefit from modern technological advancements while preserving the integrity and reliability of your aircraft’s original fuel system.
