Review LYCOMING Sl18110 Superior Oil Pump Doddy And Impellers

The Lycoming SL78528, SL181109A, and SL18110 superior O-320 oil pumps are essential components of the Lycoming O-320 series engines, known for their durability and reliability in various aviation applications. These pumps are designed to maintain the consistent flow of engine oil, ensuring optimal performance and longevity.

The SL78528 and SL181109A oil pumps share several similarities. Both pumps are driven by the engine's accessory gear and feature a gear-driven design for efficient oil transfer. They are also constructed using high-quality materials, including billet aluminum housings and hardened steel gears, ensuring robustness and resistance to wear.

The key difference between the two pumps lies in their impeller designs, which cater to distinct engine oil pressure requirements. The SL78528 oil pump comes with Doddy impellers, which provide a higher oil pressure output compared to standard impellers. These impellers are particularly suitable for engines operating under high power settings or in environments with increased oil contamination.

On the other hand, the SL181109A oil pump features standard impellers, which deliver a standard oil pressure output. These impellers are ideal for engines operating under normal conditions and do not require the increased oil pressure output provided by the Doddy impellers.

The superior O-320 oil pump, which includes the SL181109A model, has undergone several improvements to enhance its performance and durability. These enhancements include an improved gear design, improved seal materials, and a more robust impeller design. These upgrades ensure that the oil pump can handle the rigors of aviation applications while minimizing the risk of oil leaks and other potential issues.

In summary, the Lycoming SL78528, SL181109A, and SL18110 superior O-320 oil pumps are crucial components of the O-320 engine series. They come in two impeller designs Doddy and standard catering to various engine oil pressure requirements. The SL181109A and SL18110 superior oil pumps have undergone several improvements, ensuring enhanced performance, reliability, and durability.

The Lycoming SL78528, SL181109A, and SL18110 superior O-320 oil pumps, specifically those with Doddy impellers, are commonly used in aviation applications. Here are some pros and cons to consider before making a purchase:

1. Durability: Doddy impellers are known for their robust design and long-lasting performance. They can handle high oil pressure and provide reliable oil circulation to the engine.
