Thanks to our years in business, we’ve seen diesel vehicles in all stages of operational use and state and of all the industries we service, plant equipment is perhaps the most abused machinery. Working in adverse conditions, varying terrains and not always running on good fuel quality, diesel engines in plant machinery are some of the hardest working out there!

Diesel fuel injector failure in plant machinery

Through our service we’ve found that a vast majority of failures that are seen in diesel fuelled plant machinery is caused by refuelling with contaminated containers. You wouldn’t risk it for a car, so why take the risk with your plant machinery? Keeping plant machines running right makes all the difference between completing the job ahead of you or experiencing unnecessary, often frustrating downtime. Plant equipment’s harsh conditions make your engine susceptible to debris to be found in the fuel system, fuel contamination and corrosion. This presents a big problem for your engine!

Common signs of issues in plant machinery

  • A rough running engine
  • Experiencing a hard start (or no start at all)
  • Misfiring of the engine
  • Cutting out under power
  • Emitting excessive exhaust smoke
  • Loss of power

Reduce faults in plant diesel injector

The above symptoms can be indicators of an even bigger problem. Not just an issue with the fuel within the machine, but a failure within the fuel system itself – more specifically, with the fuel injectors or fuel pump. At United we’ve worked with a number of customers who operate plant machinery and understand the needs and demands owners have for the fuel systems in their equipment. If not diagnosed and repaired correctly, these problems can escalate and lead to severe engine damage and expensive repairs, taking your equipment out of action – with often costly consequences!

One of the things we try to educate our customers on is the importance of regular parts maintenance and cleaning and use of quality diesel fuel. These are both key factors in keeping your fuel system running correctly. In the event a fault or problem does arise, you need a solution. Your machinery will need quality, reliable and affordable diesel fuel system parts, either repaired or new (depending on the depth of the problem) – and you need them fast! We offer a diagnostic service on diesel injectors and fuel pumps for a wide range of plant systems including Caterpillar, Kubota, Doosan and John Deere, to name but a few. Get in touch with the team about your fault, or if you’re looking to invest in regular maintenance to maintain the health of your diesel engine. Did you know – we offer professional cleaning services? With our DPF cleaning services, we can remove the build up of soot and debris that can reduce efficiency, minimising downtime and costs – returning vehicles to like-new.
