Industrial Generators: A Guide to Maintaining Your Equipment

An industrial generator is a key piece of equipment for many business owners, engineers, contractors, and even homeowners. It provides a guarantee that a building or site will always be powered and operational, even when electric mains are not working. Given its role as an emergency backup, keeping an industrial generator working is a high priority for many people. This requires regular maintenance, adequate storage, and thorough cleaning of a unit on a regular basis.

Consumers who are new to generator ownership may need some general guidelines to follow when it comes to maintaining industrial generators. Tips on running maintenance checks, replacing parts, and cleaning the generator can make a big difference in ensuring its performance in the long run. Consumers running these types of maintenance checks on a generator can also benefit from knowing where and how to buy quality parts and accessories for a generator. While traditional vendors of industrial equipment may have some options available, these dealers are not always easy to find in all areas. Online aggregators such as eBay offer a sizable catalogue of options for buyers who want to purchase industrial generators.

Maintenance Tips for an Industrial Generator

Maintaining an industrial generator involves regular visual checks, cleanings, and parts replacement. The first consideration of any maintenance programme is adhering to safety protocols. Dealing with a large-scale industrial tool such as a generator demands conscientiousness from an owner during maintenance checks.

Safety Considerations When Maintaining a Generator

Generators operate using combustion engines and, as such, emit carbon monoxide. This gas is colourless and odourless, and you may not be aware of a leak before it is too late. For this reason, it is essential that any maintenance run on a unit is done in an open and aerated space. You may also want to wear protective goggles during maintenance work, along with work gloves. When maintaining a generator, you deal typically with many bits of wire, sharp edges, and fluids, any of which can cause irritation or even injury. Protecting yourself adequately with safety gear is a wise precaution to take.

Basic Maintenance of an Industrial Generator

As a first step in your maintenance process, run a visual check of the unit's overall condition. You want to keep an eye out for any signs of wear and tear. This might be parts that have corroded slightly or loosened during operation. Generators are subject to a good deal of vibration, which can loosen parts even after a few uses. If you see a part that has come loose, secure it back into place. If you are unsure of how a part works, consult with a professional.

As a second step in the process, change out the generator oil and any filters used in the unit. Use your owner's manual as a reference, if necessary. It is also a good idea to keep records of all your filter changes and oil changes in case you forget how long it has been since the last change. The generator oil in a unit should always be at the recommended operational levels.

Regular Replacement of Key Parts

There are certain parts within a generator that should be replaced on a regular basis. Some should be replaced as a matter of course, even if the unit has not been used, while others may only need to be replaced after a prolonged period of use.

Replacing Spark Plugs

Spark plugs in a generator should, of course, be checked on a regular basis. These ignition devices are essential to the operation of a generator, as they are the key component that starts the unit's engine. A faulty spark plug all but ensures that a generator cannot start. Cleaning spark plugs on a regular basis can be helpful. You can remove them carefully with a ratchet wrench and brush off any caked-on dirt or debris. You can also treat the firing end of the spark plug with brake or carburetor fluid to keep it clean.

In general, however, it is a wise course of action to just replace spark plugs on a regular basis. Many generator owners follow an annual or even bi-annual schedule of replacement when it comes to spark plugs. Even with quality maintenance of a spark plug, it can simply be a more foolproof choice to have a brand new plug installed regularly.

Replacing Bolts

The bolts that hold together a generator are another component that may need replacing after excessive use. The constant rattling and vibrating of a unit can loosen and stress bolts over time. If a generator has been used consistently over a period of time, make sure that you check the bolts and tighten them. In cases where a unit is under an undue amount of pressure, you may need to replace bolts to ensure that the generator remains consistent and functional. A loose bolt can lead to stress in the overall system and affect operation.

Replacing Gasket Heads and Pistons

The gasket heads and pistons in a generator are other parts that may come under strain during use. If you have been running your generator consistently, you may need to replace these components, as well. Look for signs of wear, such as stress fractures and cracks in the bodies of either part. If there is any sign of wear, replace the part to ensure ongoing, proper performance.

Professional Maintenance Checks

There are certain components in a generator that need to be calibrated on a regular basis. Unless you are a professional yourself, you probably want a professional technician to run these checks and calibrate these devices. Regular calibrations should be run on a generator's turbocharger, fuel pump, injector, and voltage regulator. The frequency with which these calibrations are run depends on how often the unit is used. If a unit is used on a regular basis, biannual calibrations may be needed. Otherwise, annual calibrations should suffice.

Keeping Your Industrial Generator Clean

An important step in generator maintenance is keeping it clean. Ideally, industrial generators should be cleaned after every use. As outdoor devices, generators often become caked with mud, condensation, and dust. The substances and lubricants within a generator that keep it operating smoothly can also cake up after use.

If the exterior of a generator is caked with debris, wipe it down with a damp rag. It is never recommended that you spray a generator with water from a hose. This can significantly damage a unit. If the dirt and debris on the exterior is too substantial for a rag, use a soft brush to flake off the debris and then follow up with a damp rag. You can also use a compressed air blower to clean out the ventilation fans on a generator. If a generator begins to show signs of corrosion, treat the spots with a corrosion inhibitor.

Proper Storage of an Industrial Generator

After cleaning, a generator should always be stored in a safe and proper spot. The ideal storage space for a generator is dry and cool. Generator covers or a tarp are a good idea since they prevent dust and debris from settling on a generator that is in storage for any period of time.

Maintenance Tools for an Industrial Generator

It is a good idea to have a set of tools on hand at all times so that you can address any situation with a generator at a moment's notice. Items to keep in good supply are work gloves, petrol, generator oil, and electrical tape. You may also want to keep extra spark plugs on hand at all times.

A supply of extension cords is another necessity that you want to keep in stock. Any cord used with a generator should have a high voltage capacity. It should also be designed for outdoor use. Cords with lock mechanisms at their connector points are also a good idea. A vibrating generator can loosen unlocked leads after a time. Keep these cords coiled and hung up when they are not in use.

Buying Industrial Generators on eBay

In order to access a variety of industrial generators, along with the parts, tools, and accessories that are needed for generator maintenance, you may want to consider leveraging the wide catalogue of options on the online site eBay. The website is designed to facilitate the purchasing process by providing you with a search interface. You can find this search box on any page on the site. Use it to run a search for industrial generators and any part or accessory you need for your maintenance project. Running a search pulls up an entire list of items related to the term you used.

Evaluating Sellers on eBay

While you look through products on eBay, you should also take some time to evaluate the sellers on the site. This helps you narrow down the best listing items for your needs. A seller's information can be accessed by clicking on the seller's highlighted name on a listing page. Scan through a seller's past listings and also look for feedback from other customers. This information helps you refine the purchasing process.


Maintaining a generator regularly is a necessary chore that can ensure its reliable operation when it is needed most. As a device that must be ready at a moment's notice, an industrial generator requires regular maintenance checks for optimal efficiency. Maintaining one of these units is a simple matter of running visual checks on parts, replacing essential components regularly, and keeping the generator dry and clean.

Before running a check on a generator, consumers may want to stock up on necessary supplies, such as protective gear, replacement parts, lubricants, and cleaners. Accessing these products is easy via an online aggregator site, such as eBay. The site brings together a wide range of vendors to give consumers the options they need to make an ideal purchase. Thanks to its user-friendly search interface, eBay gives users a fast way to initiate the purchasing process. Buyers can also choose to search locally at home improvement stores, but industrial generators often have to be purchased through industrial equipment suppliers.
