5 Common Repairs Your Diesel-Powered Forklift May Need


If you have a diesel-powered forklift, it’s probably a key element to your business model and regularly handles heavy loads in a tough working environment. However, just like any machinery, it will suffer wear and need the odd repair.


In this short article, we look at 5 of the common repairs diesel-powered forklifts may need during their lifespan, and how to address them effectively to ensure your forklift continues to provide the service you require.



  1. Fuel System Issues

    The fuel system is the lifeline of your diesel-powered forklift, but problems can arise for several reasons, including contaminated fuel, clogged fuel filters, malfunctioning fuel injectors etc. The best way to prevent these issues is to regularly check and replace fuel filters, to help prevent debris from entering the engine, and, if you notice a decrease in performance, or excessive smoke, consult a qualified forklift engineer.


  2. Engine Overheating

    Diesel engines naturally generate a lot of heat, especially in a hardworking forklift. And, overheating can lead to expensive repairs, and costly downtime due to the time the forklift is out of action. Common causes of overheating include coolant leaks, malfunctioning thermostats, clogged radiators etc.

    To help prevent overheating, regularly inspect coolant levels and hoses, and keep the radiators clean as possible. If you do have an overheating scenario, to avoid engine damage, we’d still highly recommend getting in touch with a qualified forklift engineer; even if topping the coolant up provided a temporary remedy to the issue.


  3. Hydraulic System Leaks

    Hydraulic leaks can occur in the hoses, seals, or connections of your forklift’s hydraulic system. These leaks not only lead to a loss in hydraulic fluid but also impact the overall performance of the forklift. To help prevent hydraulic leaks, regularly inspect the hydraulic system for any signs of leakage, and address them immediately by replacing hoses or seals, and tightening loose connections.

    If in doubt however, always consult a professional and experienced forklift engineer, who will have more knowledge of the forklift model, and be able to source the correct spare parts if necessary.


  4. Electrical System Malfunctions

    The electrical system in your diesel-powered forklift is responsible for all sorts of critical functions, such as the ignition, lights, gauges, and essential and crucial safety systems.

    Electrical system malfunctions can include issues with wiring, fuses, or battery connections, so make sure to regularly inspect electrical and battery connections, and if possible, replace faulty wiring or fuses.
    However, if you’re not trained in forklift maintenance, especially regarding the electrical system of your forklift, always talk to a qualified forklift technician, so that they can offer guidance, or carry out the repairs for you.


  5. Transmission Problems

    The transmission of your forklift plays a vital role in shifting gears and transferring power from the engine to the wheels. Common forklift transmission issues include slipping gears, shifting difficulties, and unusual noises.

    To help prevent transmission issues, regularly check the transmission fluid level and condition as specified by the manufacturer, and address any transmission issues as promptly as possible. Again, we’d highly recommend speaking to a technician qualified in forklift repairs if you have any issues with your forklift transmission, both for the safety of forklift operators and to help avoid more costly repairs in future.
