Main Factors In Hydraulic Pump Failure And What You Can Do About Them

Hydraulic Pump Failure

Hydraulic pumps are used in skid steers and tractors and other farm equipment. The primary role of a hydraulic pump is to produce the energy required by the system for performing different tasks.

Like other machines, hydraulic pumps can develop problems over time and stop working. If you’re noticing a drop in your hydraulic pump’s performance and other signs of hydraulic pump problems, have a professional inspect the device and perform necessary repairs.

Every hydraulic pump owner should know about these common causes of hydraulic pump failure.

Contamination

Airborne particles, debris, and metal parts can enter the hydraulic fluid, contaminating it. Contaminated hydraulic fluid can damage hydraulic pump components and cause them to deteriorate faster. If the hydraulic fluid appears cloudy or milky, water contamination has occurred.

Water in your hydraulic pump can create a corrosive environment, wearing out hydraulic pump components prematurely. Also if air from outside enters your hydraulic pump (aeration) through leaks and loose connections, it can damage the parts of the device.

Overheating

There are several causes of hydraulic pump overheating-from a blocked or clogged filter to low reservoir fluid and lack of maintenance. Regardless of the cause, overheating can lead to oxidation of the hydraulic fluid (which only makes matters worse). It can cause thermal expansion of hydraulic pump components, leading to excessive wear.

Cavitation

Air bubbles can form and eventually implode in the hydraulic fluid, causing cavitation, which can lead to pitting of the pump’s surface. Low hydraulic fluid levels and restricted fluid flow can also lead to cavitation.

Poor Quality Hydraulic Fluid

The wrong type of hydraulic fluid can affect hydraulic pump performance and ultimately lead to pump failure.

Improper System Design

A wrong-size hydraulic system can lead to overloading and premature failure. Incompatible pump components can affect system performance and lead to excessive wear and tear.

Tips to Prevent Premature Hydraulic Pump Failure

Follow these tips to increase the service life of your hydraulic pump.

  • Regularly check the hydraulic fluid to make sure it is clean and free from contaminants. Use high-quality filters to keep debris and dust out of the system
  • Low hydraulic fluid levels can lead to cavitation. Check fluid levels at regular intervals and top up as required
  • High hydraulic fluid temperature can damage the pump components. Ensure good airflow around your hydraulic pump and use coolers if necessary to prevent hydraulic pump overheating
  • Use the hydraulic fluid recommended by the pump manufacturer
  • Periodically check the system’s pressure using gauges. Replace damaged or worn out seals
  • Visually inspect your pump for signs of damage such as leaks. Lubricate components and replace clogged filters

Cessna Hydraulic Pump Identification Guide

Oliver Tractor Cessna Hydraulic Pump

Cessna hydraulic pumps are known for their reliability and superior performance. There are three types of Cessna pumps – gear pumps, piston pumps, and vane pumps. Gear pumps utilize meshing gears, whereas Cessna piston pumps use a series of pistons to pump hydraulic fluid. Vane pumps use a rotating vane (located inside a cavity) to move hydraulic fluid. They produce less noise and handle low-viscosity fluids better.

Over the years, many Cessna parts have been redesigned or replaced. If you own an old Cessna and are having trouble identifying the Cessna hydraulic pump model that powers it, you have come to the right place. Here are some ways to find out the model of your Cessna hydraulic pump.

Locate and Read the Identification Plate

Every Cessna hydraulic pump has an identification plate that contains important information about it, including the model number, a unique serial number (read the serial number of your hydraulic pump to find out its manufacturing date and batch number), and sometimes operational specifications. This information can be used to track the pump’s service history.

Check the Model Number

Every Cessna hydraulic pump is assigned a unique model number according to its capabilities and suitable applications. The model number of your pump can tell you about its flow rate, pressure capacity, and whether it is designed for a light recreational aircraft or a heavier commercial airplane.

Refer to the Manual

Your hydraulic pump owner’s manual contains important information such as pump specifications, usage guidelines, and maintenance recommendations, which can help you assess the pump’s suitability for a specific application.

Examine Physical Characteristics

Cessna hydraulic pumps come in a variety of shapes and sizes. The configuration of ports and connectors of a pump can be very different from that of other models. Smaller pumps are usually designed for single-engine aircrafts. They are less complex than the ones used in larger twin-engine aircrafts. If the identification plate is missing or illegible, observe these physical characteristics to determine the model and type of your hydraulic pump.

Seek Professional Help or Check Online Databases

Contact Cessna’s technical support team or consult a trusted distributor. You can also check an online database or catalog. All you need to do is enter your pump’s serial number to get important information about it.

Exploring the Essential Components: Understanding Cessna Hydraulic Pump Parts

Cessna Hydraulic Pump

Cessna hydraulic pumps are used in aircraft, ground support equipment at airports (such as vehicles used for towing aircraft), material handling systems, and boat steering systems. They are durable, low maintenance, and can operate in the harshest work environments.

Here are the main components of a Cessna hydraulic pump.

Pump Housing

It encloses and supports the internal components of the pump. Pump housing is usually made of a durable metal that can withstand high pressures exerted during operation.

Inlet and Outlet Ports

These are the pathways through which hydraulic fluid enters and leaves the pump. The inlet port draws hydraulic fluid from the reservoir into the pump. Pressurized fluid is forced out through the outlet port.

Gears or Pistons

A gear pump utilizes a set of interlocking gears, whereas a piston pump uses a series of pistons to pressurize hydraulic fluid.

Pressure Relief Valve

To prevent damage, keep the pressure within the specified range. When the pressure gets too high, the pressure relief valve opens to release some of the hydraulic fluid back into the reservoir or a bypass line.

Pump Drive Gear

This connects the pump to the aircraft’s engine or electric motor, transferring mechanical energy (required to move internal pump components) to the hydraulic pump.

Seals and Gaskets

These prevent leaks and maintain the optimum pressure. They seal the gaps between the parts of the pump.

Bearings

They help reduce friction between pump parts and wear and tear on the pump.

Control Valves

Some hydraulic pumps have control valves that help regulate the flow of hydraulic fluid.

Tips to Maintain Cessna Hydraulic Pumps

Cessna hydraulic pump maintenance is a matter of necessity rather than choice. Regular maintenance prevents costly problems and keeps your Cessna hydraulic pump working at its peak efficiency.

Here are some tips to help you keep your Cessna hydraulic pump in good working order.

Perform Regular Inspections

Periodically inspect hoses, fittings, and connections for signs of leaks and damage. Fix any problems immediately to prevent them from snowballing into major issues.

Maintain Proper Hydraulic Fluid Levels

Periodically check hydraulic fluid levels and top up if required. When replacing hydraulic fluid, follow the manufacturer’s instructions. Use the type of fluid suggested by the manufacturer.

Clean the System

Dirt and debris can contaminate hydraulic fluid. Cleaning your Cessna hydraulic pump regularly is a great way to prevent contamination. Follow these steps to clean your pump.

  • Turn off and depressurize the pump.
