The construction sector is a demanding sector requiring a lot of toil and effort. The equipment used in the sector is usually rugged and thus requires mighty engines to power them. Operations like digging, lifting, drilling, and moving loads are performed by the equipment, thus it is a prerequisite for the engine to be rugged and sturdy. Along with this, it is required that the construction equipment diesel engines must produce an optimum amount of torque and power to tackle the challenges thrown at them.
While a diesel engine is a magnificent piece of machinery, it too needs some maintenance on a timely basis. In this article, we will be talking in depth about the guidelines and steps you need to inculcate to ensure your engine gives ideal performance when required. Following these steps will lead to a drastic reduction in downtime and improved efficiency.
Let’s have a look at all the essentials that are essentials when it comes to maintaining your diesel engine
Keeping diesel engines clean
Dirt and debris are part and parcel of the construction sector. Thus it is pretty obvious for engines to accumulate them during operations. Gathering of dirt can have severe repercussions on the performance of the engine. One of the prerequisites you can do is to ensure the engine is cleaned at regular intervals of time.
Buildup of dirt and debris can block the airflow leading to overheating of the engine. This can result in a reduction in power production, and an increase in fuel consumption which can adversely damage the engine. Thus it is required that diesel engines for construction machinery are regularly cleaned with degreaser and water. Along with the engine, it is essential to see that the air filters are not clogged with dirt.
A thorough inspection of the engine must be done. This will help in identifying leaks or damage (if any). Leaks in the hoses can cause the engine to spill oil or coolant, which can lead to serious problems. If such leaks are found, it is imperative to get them repaired at the earliest convenience.
Lastly, it is indispensable to keep the engine compartment free of debris, such as leaves and grass. This debris can block the airflow, leading to overheating of the engine.
Using the right grade of fuels and additives
Using the correct and good quality grade of fuel is of prime importance. An incorrect grade of fuel can damage the engine and its parts leading to excessive wear and tear. In addition to this, fuel additives should be used. They can have a huge impact on improving fuel efficiency, reducing emission levels, and keeping the engine clean. Proper fuel selection can also help in the prevention of engine knocking and extend its life.
Certain fuel grades are designed for specific temperature ranges, ensuring reliable operation in several weather conditions, which is often critical on construction sites.
Timely changing of oil and filters
Changing oil and filters regularly is extremely crucial to ensure the peak performance of the off-highway diesel engine for construction. Used oil contains contaminants and thus that affects its efficacy. It loses its lubricating properties leading to an increase in wear and tear of engine components. Regular changing of oil and its filter ensures that clean oil is delivered to the engine at all times. The frequency of oil changes can vary from one equipment to another. Some of the factors that play a role in this include the type of equipment, operating conditions, and manufacturer’s recommendations.
Generally, it is recommended to change the oil every 250-550 operating hours or every 4 to 6 months, whichever comes first.
Monitoring of coolant levels and its quality
Inspection of coolant levels must be done, before and after each work shift. It should also be taken into account that the correct type of coolant is used and refilled to the right amount. To identify the required level of coolant, a glance at the markings on the expansion tank or reservoir would help. Ideally, the coolant level should be between the “full” and “add” marks when the engine is cold. Along with this, you should look out for signs of coolant leaks, such as the formation of puddles or white residue. The cooling system needs to be flushed at recommended intervals to remove contaminants. It should also contain adequate corrosion inhibitors. Rightfully following the above steps will ensure the smooth operation of the diesel engine for heavy machinery.
Inspecting all hoses and transmission belts
Hoses and power transmission belts are key parts of every construction equipment diesel engine. Failure of them can lead to a prolonged downtime to the engine. Hoses should be inspected for cracks, bulges, swelling, or hardening. They need to be secured tightly using clamps. Any form of twisting of hoses should be avoided. If found faulty, they should be replaced as soon as possible.
When it comes to transmission belts, watch out for signs of cracks, fraying, glazing, or missing sections. The tension in the belt should be proper. It should neither be too loose nor too tight, as that can cause premature wear. The belt should be properly aligned with the pulleys. If worn or damaged belts are found, they should be replaced immediately. In addition to all this, the belts must be kept clean and free from oil, grease, and other contaminants.
We hope this article helped you gain insights into the maintenance essentials you ought to keep in mind for the smooth operation of diesel engines for construction machinery.
