AE Gibson & Sons Service and Support for Hydraulic Power Units

With over a hundred years of experience in manufacturing and after-sales support, the AE Gibson and Sons team understands the importance of your equipment asset performance, efficiency and reliability, to ensure customer satisfaction.

Hydraulic power units provide the energy necessary to run your plant and equipment. While hydraulic power units are used in many factories, and are such a critical part of a productive operation, many of these units are not being maintained properly, risking costly downtime, or catastrophic failure.

Preventative maintenance is a necessity to keep units running as long as possible, which is why it is so important that hydraulic power unit owners are aware of the need for maintenance. Whether you do it yourself, or hire a professional to do it, your hydraulic power unit needs maintenance.

When a hydraulic power unit breaks down, only a highly trained professional should conduct repairs. Routine preventative maintenance should be completed following the manufacturer’s instructions for maintenance. Some of preventative maintenance can be completed on your own without risking the safety of those using the power unit. If you are not confident to work on your hydraulic equipment, or need help with anything, call our professional team to support you.

The basics of general maintenance include:


Have increased cycle times crept into your plant and equipment? In other words, has your machine slowed down? You could be compromising your whole hydraulic system without knowing. Inefficient components draw more power and drive up the running costs of your operation, so it’s always a good idea to be aware of how your equipment is performing. Understanding the health of your pump can help mitigate future downtime and costly repairs.


Hydraulic hoses should be regularly inspected and replaced before they fail and cause major issues to your power unit. Poorly maintained hydraulic hoses can result in costly downtime, catastrophic failure to assets, safety risks and environmental hazards. This is preventable, and our team at AE Gibson & Sons can assist with replacing the hydraulic hoses saving you time and money, and to ensure your equipment is kept running as long as possible.


The filter on your power unit may have an indicator that lets you know when it needs to be cleaned or changed. Make sure to check the indicator directly after starting up the system to ensure you take care of it before operating the power unit.

If your unit does not have an indicator, check the manual of your power unit to determine how often you need to take care of the filter. For replacements, verify that you are replacing it with a similar type as indicated by the manufacturer. If you are cleaning the filter, be sure to follow the instructions for cleaning to ensure you remove all contaminants before reinstalling.


The suction strainers on your machine probably need to be cleaned after the first 10 hours of use and then every 100 hours of use after that. The exact cleaning times may vary by manufacturer.


You can check the reservoir to determine if oil needs to be added. Do this periodically, especially when you first start using the power unit, to ensure that the level does not drop lower than it should be. Ideally, check the reservoir after the first 100 hours of use.


Make sure the oil is not running too hot. You can tell oil has been running hot when it is much darker than new oil. You may also sense a burning odour.


The oil in your hydraulic power unit needs to be changed based on the requirements of the manufacturer. Typically the oil will need to be changed somewhere between 1,000 and 2,000 hours of use. The rate of oil changes will vary based on the demands put on the power unit, include the environment it is used in and the application that it is being used for.

When you identify the need to change the oil, consider changing over to new technology oil products to reduce the risk of fire, as experienced with traditional mineral oil products.


When your hydraulic power unit needs to run strong and long, it pays to have a professional maintenance team. AE Gibson & Sons is your source for preventative maintenance and repairs, including checking and replacing hydraulic system components and custom power units.
