What Do We Check During a Diesel Generator Service?

When you book a generator maintenance or service package from Solent Power, we'll perform either a minor or major service. Both types of checks are important, but they're performed at different times. The type you choose will depend on how often you use the generator, its age, and other factors.

Minor Diesel Generator Service

Minor generator services are about preventative maintenance and performing routine checks. They usually include the following:
  • Oil and Filter Changes: Evaluating your generator's oil and changing the filters to ensure the engine continues to perform.
  • Fuel Quality Inspections: Assessing the fuel system for contamination, blockages, and leaks, which can result in low fuel levels.
  • Air Filters: We'll also examine your air filter system to ensure no obstructions or debris are blocking air intake. If necessary, we'll change the filters.
  • Battery Maintenance: Cleaning battery terminals, assessing them for damage, and testing the voltage.
  • Coolant Checks: We'll also verify that your generator's coolant levels are sufficient to prevent overheating.
  • Visual Inspection: Over time, the generator will experience wear and tear. Visual inspections are essential to regular servicing, as they let us identify and fix potential faults.
  • Control Panel Inspection: We'll check that your generator's control panel is working correctly, including testing the indicators and alarms.
  • General Load Test: We'll run the generator under a specific load to ensure it can perform to its desired capacity.

Major Diesel Generator Service

Major generator services enable us to perform a more detailed assessment and extensive checks. We'll usually recommend this package as an annual service or if your generator runs frequently. Our major maintenance package includes everything in the minor package and the following:
  • Full Engine Inspection: Besides general engine maintenance, we'll also perform a full inspection, including checking the pistons, valves, and cylinder heads.
  • Fuel Injector Service: Our experts will also ensure efficient fuel economy and combustion.
  • Exhaust System: We'll assess the exhaust system for corrosion signs, leaks, and blockages.
  • Cooling System: Preventing engine damage is vital, and this can involve refilling and cooling the system. This also ensures your generator will provide support in a power outage.
  • Alternator/AVR Inspection: Our engineers will assess the power systems for output stability and voltage regulation.
  • Load Bank Testing: We'll also perform advanced load bank testing, including staggered loads if needed.
  • Detailed Reporting: While the minor service provides a general report and actionable points, you'll receive an advanced service report detailing how to prolong your generator's lifespan.

Benefits of Regular Generator Servicing and Maintenance

When you book a generator service and maintenance package from Solent Power, you can look forward to a variety of benefits, including peace of mind, affordability, and long-term performance. Here's why our clients choose our comprehensive servicing and generator maintenance plans.

Improved Reliability

Generators are complex machines that may go unused for months or even years. However, you'll need to ensure they're reliable and provide backup power when needed.

Our maintenance technicians can identify and fix generator faults, allowing you to benefit from standby power when required.

Longer Generator lifespan

Routine maintenance is key to identifying issues with critical components and prolonging the generator's lifespan.

For example, changing the oil filters and load testing is more affordable initially than the costs associated with repairs or purchasing replacement parts. Standby generators can last for decades, but ongoing maintenance is a crucial component of that.

Higher efficiency

By ensuring your generator continues to achieve peak performance, you can reduce its carbon footprint and preserve fuel usage.

Our maintenance services are more cost-effective than the ongoing expenses associated with frequent refuelling, and many organisations have sustainability initiatives that they must meet.

Lower Repair Risk

Minor issues are easy to fix, and you can save money by identifying them early. So, while it might seem like you can save money on a thorough inspection in the short term, you should factor in the costs of replacing the generator.

Remember, diesel generators are investments, and prevention is always cheaper than the cure.

Compliance and Record Keeping

Many industries have strict regulations that they must follow, including health, safety, and environmental guidelines.

Generator maintenance ensures compliance with these regulations while protecting your warranty. Many manufacturers will refuse to cover repairs and replacements if you don't invest in maintenance.

Health and Safety

Fuel leaks, faulty electrical systems, and damage to your generator's components can all result in severe health and safety issues. Industrial, commercial, and health settings should be particularly worried about maintaining strict safety protocols.

Our maintenance services will assess the support your generator requires and ensure that it doesn't cause any hazards.

Most diesel generators will require a service between 250-500hrs or every 12 months. We recommend testing your generator regularly to ensure it is functioning correctly and to prevent any nasty surprises when you lose power. This can be done weekly or monthly as a simple 5 minute test. Ask us for more information about this.

In our experience most people who try to service their generator themselves will not be thorough enough to spot potential failures. The basic service requirements of replacing oil and filters is simple enough, but there are many things that we check such as engine protection functions, alternator checks, battery testing etc that only an experience technician will know how to do correctly. We recommend always engaging a competent generator service company near you.

If you do get stuck and want to have a look at an issue yourself please check out our fault finding guide here

Generator oil should be replaced every 500 hours for diesel generators or done every year. In standby generators this can be extended by sampling and testing the oil to ensure it is not contaminated. After time, generator oil degrades during use and loses its lubricating properties and cooling properties, resulting in engine wear which can cause engine failure.

Standby generators can be serviced without any disruption to your power supply or operations. It is completely non-intrusive. Servicing of your generator being used daily for powering machinery will need to be planned around usage. We are flexible and can work with you to find a time that suits you best.

A typical generator service carried out at your workplace will usually range from £300 upwards. This price increases as the size of the generator increases as the service will take longer to carry out.

Service costs vary depending on the level of generator service performed. A minor generator service includes a full inspection and test and report. A major service includes oil change, wet filter replacement and sometimes other works such as battery changes, belts and coolant etc.

The distance travelling to your site will also affect the price so it is important to use a generator service company near you.

We will always endeavor to fix any issues we find during our visit as a convenience for you and to try to save you money on a second visit. For basic parts such as failed relays or small hoses or buttons we may carry something in the engineers vans that can be fitted to help you. If a component or part is required we will identify this and explain the issue to you and provide costs prior to sourcing and replacing.

A diesel generator service varies from around 2 hours to a full day. Some factors that affect the length of time are the generator size and application. A large generator will take longer to change the oil or a High voltage generator may take much longer due to access, permits and isolations required.

A minor generator service is a basic inspection and test, which takes around 2 hours. A major service is much more thorough and filters and oil are replaced and sometimes the generator may also be loadbanked which adds more time to the job.
