Cessna hydraulic pump identification guide. This article is a bit of a long read, but helps you identify the different types of Cessna hydraulic pumps.The purpose of this article is to help you identify the different types of Cessna hydraulic pumps. Some are quite common and others are rare, but if you ever have to replace one, it’s important to know what type you’re dealing with.

There are three basic categories of Cessna hydraulic pumps:

1) The original “round” style which first appeared in 1965 on all aircraft except 172s and 180s which came with the newer “square” style pump until they were replaced by more modern units in 1974. These older models continue to be used today in many aircraft including Citabrias, 172Bs and 182s.

2) Newer square style pumps which first appeared on 172Bs in 1974 and on Cessnas built after that date until they were replaced by an even newer generation of pumps starting in the late 1990s (which I’ll call the 3rd generation).

3) The newest generation – called “4th generation” for lack of a better name – which is used on all aircraft built after 1999 including some older modelsthat have been modified to use new pumps. I’ll describe each generation in detail below.

Eaton Acquires CESSNA

Although Cessna Hydraulics, devoted predominantly to land based hydraulic systems was acquired by Eaton Hydraulics from the Cessna Corporation in 1988, many models of its pumps and motors continue to be manufactured.  The Cessna Corporation itself was founded in 1927, very well known for its aircraft. The company was purchased by Textron, Inc. in 1992.  Cessna Aviation still produces hydraulic components for aviation  applications.  They’re found in engines, motion control, and fuel systems, as well as landing gear mechanisms.

Under Eaton, Cessna Hydraulics meet the needs mainly of mobile and industrial hydraulic equipment manufacturers.  The company continues to refine the product line with reductions in component weight and improvements in reliability. The units can be customised in many cases where this is required and possible.  The Cessna range under Eaton’s ownership has continued to evolve in particular in the gear and piston pump area whilst many of the valve designs have been superseded by non interchangeable alternatives.

old cessna hydraulic pump identification

Many Cessna owners are struggling to identify their old airplane parts. As you may know, many cessna parts were replaced or redesigned over the years and it can be difficult to pin down exactly what part you have. In this article we discuss how to identify old cessna mechanical pumps.

Identifying Cessna Hydraulic Pump Models

When it comes to maintaining and repairing aircraft, identifying the correct Cessna Hydraulic Pump model is crucial. These pumps, integral to the operation of various aircraft systems, come in numerous models, each designed to meet specific operational needs. This section explores the key features that help in the identification of Cessna Hydraulic Pump models, including model numbers, physical characteristics, and operational specifications.

Model Numbers and Physical Characteristics

The first step in identifying a Cessna Hydraulic Pump is to look at its model number. Each pump is assigned a unique model number that reflects its specifications and applications. For example, the model number can tell you about the pump’s flow rate, pressure capacity, and whether it’s designed for a light aircraft or a more robust commercial airplane. These numbers are not arbitrary; they are part of a systematic approach to categorize and identify each pump’s capabilities and compatibilities.

In addition to the model number, physical characteristics play a significant role in identification. Cessna Hydraulic Pumps vary in size, shape, and the configuration of ports and connectors. For instance, a pump used in a single-engine Cessna might be markedly smaller and less complex than one used in a larger, twin-engine aircraft. Observing these characteristics can provide immediate clues about the pump’s intended use and compatibility.

Operational Specifications

Understanding the operational specifications of a Cessna Hydraulic Pump is equally important. Specifications such as the pump’s rated pressure, flow rate, and efficiency at various speeds can help identify the correct model for specific aircraft requirements. These specifications are usually found on the pump’s data plate or in the technical manual.

Serial Numbers and Data Plates

The serial number and data plate on a Cessna Hydraulic Pump offer a wealth of information for accurate identification. The serial number is unique to each pump and can provide details about the manufacturing date, batch, and specific model nuances. The data plate, usually affixed to the pump’s body, contains critical information, including the model number, serial number, and sometimes, operational specifications. These identifiers are crucial for ensuring the pump matches the aircraft’s requirements and for tracking the pump’s service history.

Cessna’s dedication to aviation safety and performance is reflected in the meticulous design and manufacturing of their hydraulic pumps. Recognizing the right Cessna Hydraulic Pump involves more than just matching numbers; it requires a comprehensive understanding of the pump’s role within the aircraft’s hydraulic system. The significance of using the correct pump cannot be overstressed, as aviation professionals often reiterate the mantra, “The right part for the right plane.” Ensuring the correct match is paramount for maintaining the aircraft’s safety, efficiency, and reliability.

Identifying Cessna Hydraulic Pump models is a foundational skill for anyone involved in aircraft maintenance and repair. By paying close attention to model numbers, physical characteristics, operational specifications, and the invaluable data provided by serial numbers and data plates, maintenance personnel can ensure that the aircraft remains in optimal condition, safeguarding its performance and the safety of all those on board.

Eaton cessna hydraulic pump code identification

Series 26 Gear Pumps can be ordered by using the following Model Code .A thirty-two digit coding system has been designed to identify the features presently available on Multiple gear pumps . The characters and their relative positions within the code identify specific features. Use the Model Code Matrix as an aid when assembling the model code for the pump with the features you desire . It may be helpful to photocopy the matrix and write the numbers and letters into the boxes as you select features.
