Truck repair & maintenance

The process of servicing a large truck involves more than the standard vehicle maintenance, according to Audi service centre. A truck is defined as a vehicle whose main purpose is to transport goods and products from one destination to another. Trucks can have a variety of sizes, speeds, power, gas mileage, model, style, and engine design. Commercial truck repairs require extra skill and will need a professional with years of experience in commercial truck maintenance to handle the job efficiently. What are commercial trucks? Here are some commercial truck examples, dump trucks, concrete mixture vehicles, tractors, an 18-wheeler.

Truck Maintenance Check List

Tire Check: Routine tire checks are very important when performing maintenance on a commercial truck of any kind. It’s not uncommon to see wear and tear on tires during truck repairs. Truck tires are about a third of the total maintenance cost of the vehicle. Professionals know what to look out for when inspecting tires on a large vehicle. Air-pressure and tread checks are mandatory.

Vehicle Fluids: It’s common for truck drivers to keep on eye out for any fluid leakage underneath their trucks after parking. If there’s an unusual leak, the vehicle is looked at by a professional, who will then do a full truck maintenance check on fluids. This will include checking the antifreeze, oil, gas, and coolant. The mechanic will also check for the amount of fluid under the hood of the vehicle.

Service Light Check: It’s recommended for truck drivers to be aware of their service lights. Service lights are the easiest way to pinpoint what exactly a vehicle would need when it comes to maintenance.

Brake Check: Brake checks would be checked regularly. Routine brake checks are important among commercial truck companies, to ensure safety for both the driver and for those around. During a routine brake check, a mechanic would see if there is a proper amount of lining remaining on the tire. Additionally, the mechanic will check for leaks within the air pressure system. Checking to see if the low air pressure warning alarm works properly is vital and should be checked regularly as well as everything else.

Air Filter Check: A clean air filter is important for a large truck transporting goods since airflow in a vehicle is vital for the engine and all the parts within it. A filthy air filter could result in a decrease in gas mileage and cause ignition problems if unchecked. New air filters are generally white and sometimes an off-white shade. However, a dirty air filter consists of dirt and debris which can result in clogging. As a result, restricting proper airflow through the vehicle. The location of a truck’s air filter can vary depending on the model.

Things To Consider While Operating Trucks

The most important thing a driver must consider while operating a commercial truck is safety. Long haul truck driving is one of the many difficult jobs available in the United States. Performing a job like this ensures on-time delivery of valuable goods and products. However, one could get tired and miss all of the signs of whether or not the truck needs urgent maintenance or not. Staying alert and awake while operating a large truck is not only safe for the driver but also of those around. A sleepy driver can miss all the important signs of potential vehicle maintenance. Over one hundred thousand severe injuries and three hundred thousand accidents can happen yearly. Being able to keep up with regular truck repair and maintenance can ensure safety for the driver and those around. On the flip-side can extend the life of the vehicle and prevent accidents on the road.

Additional Hazards To Look Out For

Other hazards to look out for when driving a large vehicle is being aware of blind spots. Blind spots can vary depending on the vehicle make and model. Other drivers may not be aware of a truck’s blind spots and might drive hazardously close. Regularly exercising caution before merging or turning can assist in a safe distance from the truck and nearby vehicles. Another hazard to look out for is severe weather. Terrible weather causes 25% of trucking accidents. Lowering the speed of the vehicle and making sure the truck’s tires aren’t bald is crucial. Drivers are recommended to take their time on icy roads. Being aware of black ice warnings and blizzards are also important. Before starting on a delivery route, be sure to check the weather ahead of time.

Cummins Engines

What engines are Cummins engine?

The RAM 2500 and 3500 engines are mostly Cummins engine. Yes, it is mostly used for heavy-duty pickup trucks. It was built to last which is why most car manufacturers use Cummins engine. The truth is there are just too many to mention and all of them are worth considering.

Who does Cummins make engines for?

Right now, Cummins makes engines for Nissan. There was a time when they used to also make engines for Ford but that time has come and gone. It is time to move on to a bigger and better deal. They browsed through the market and found out Nissan gave them the best deal possible. With huge deals on the line, they made a pretty wise decision. Truck drivers are often the beneficiaries of Cummins engines. Racecar drivers also benefit due to how durable the engines are. It will only be a matter of time before more people make use of Cummins engines. It just takes a matter of discovering how good the engines are. To top it all off, the designs of the engines are also great.

What is the best Cummins motor?

The Cummins 5.9 L 12-valve Turbo Diesel engine is available in a lot of pickup trucks. Once more people take notice of it, then it will be available in even more pickup trucks. The engine was known for achieving good mileage which is pretty important. Besides, you would want to get the most out of your engine. It also has the ability to produce such incredible torque. When you compare them with other motor engines, you will see a huge difference. There is no doubt you will think you should have found this model sooner than you did. Cummins is actually known to start the way pickups use turbodiesel engines. Thus, we owe a lot to Cummins because driving pickups just got a whole lot better when using their engines.

Is Cummins a good engine?

Not only is Cummins a good engine but it is a pretty good one at that. In fact, it was designed to be the perfect engine. It was not designed to be for racing alone. Cummins can run over a million miles which is far more than their closest competitors. That speaks a lot about durability so if you are looking for an engine that would last several lifetimes then this is the best option out there. Like other engines, you must properly maintain your Cummins engine for it to last a long time. If you don’t then it won’t be long before it breaks down. That won’t be good news especially if you are aware of how much you spent for it. If it is one thing Cummins is known for, it is reliability. They have been making nice engines for a long time and truck drivers know how durable their products are. Thus, they won’t even hesitate to buy their new models because they know they were tried and tested.

What engines do trucks use?

What engines do trucks use?

A truck is a motor vehicle that transports cargo from one place to another. Trucks vary greatly in configuration, size, and power. Most smaller trucks are mechanically similar to some automobiles.

Commercial trucks or lorry are large and powerful. They include firetrucks, suction excavators, concrete mixtures, refuse trucks, tractor, and straight trucks.


What are the different classes of trucks?

Trucks are classified base on the Gross Vehicle Weight Rating (GVWR). GVWR indicates the maximum truck weight and load a truck can carry. It includes truck’s weight, plus the cargo, fuel, passenger, and even the trailer tongue.

The GVWR determines the vehicle class and the regulations it has to follow. The type of driving license determines the vehicle class you are allowed to drive. There are three main categories of trucks:

  • light-duty trucks
  • medium-duty trucks
  • heavy-duty trucks


1. Light-duty trucks

Their GVWR is less than 10,000 lbs or 4536 Kgs.

Class 1

They include a sports utility vehicle (SUV) or Sedan and have a GVWR of not more than 6,000 lbs or 2722 Kgs.

Class 2

They include utility van and have a GVWR of 6,001 – 10,000 lbs or 2722 – 4535 Kgs.

Class 3

They include a minibus and have a GVWR rating of 10,001 – 14,000 lbs or 4,536 – 6,350 Kgs.


2. Medium-duty trucks

Their GVWR range from 14,001 – 26,000 lbs

Class 4

They include a step van and have a GVWR rating of 14,001 – 16,000 lbs or 6,351 – 7,257 Kgs.

Class 5

They include a bucket truck and have a GVWR rating of 16,001 – 19,500 lbs or 7,258 – 8,845 Kgs.

3. Heavy-duty trucks

Their GVWR is higher than 26,001 lbs or 11,794 Kgs.

Class 7

They include a city transit vehicle and have a GVWR rating of 26,001 – 33,000 lbs or 11,794 – 14,969 Kgs.

Class 8

They include a refuse truck and have a GVWR rating of above 33,001 lbs or 14,969 Kgs.


What are the different types of diesel engines?

Most modern trucks use diesel engines. Some small and medium trucks in the US, Mexico, and Canada use gasoline engines. Diesel engines gain energy by burning the fuel sprayed or injected into the compressed, hot air charge in the cylinder. There are two main classes of diesel engine: two-stroke and four-stroke

Trucks use different kinds of diesel engines. Some of the common types of diesel engines include:

  • CAT Diesel
  • Cummins
  • Detroit Series 60
  • Volvo


They are categorized based on different characteristics. Below are some of the common ways of categorizing diesel engines:

1. By number of strokes

  • Two-stroke cycle
  • Four-stroke cycle


2. By power output

  • Large > 750 kW
  • Medium 188 – 750 kW
  • Small < 188kW


3. By connecting rod and piston

  • Double-acting piston
  • Trunk piston
  • Opposed piston
  • Crosshead piston


4. By cylinder bore

Commercial vehicle and lorry engines: 90…170 mm

Passengers car engine: 75…100 mm

Medium-speed engine: 240…620 mm

Low-speed engine: 260…900 mm

High-speed engine: 165…280 mm


5. By engine speed

Slow speed engine (less than 300 rpm)

Medium-speed engine (300 to 1,000 rpm)

High-speed engine (above 1,000 rpm)


6. By cylinder arrangement

The physical arrangement of the cylinders, whether inline (straight), V, or flat (boxer).


Advantages of buying a diesel truck

There are several reasons why one would opt to buy a diesel truck rather than a gasoline car. Some of these reasons include:


1. Diesel engines are highly efficient

The combustion process in diesel engines is a lot of leaner, meaning it does not have to burn much fuel to power the truck. Diesel engines are also more energy-rich and use less fuel compared to gasoline engines.


2. Less maintenance

With a diesel-powered truck, you don’t have to worry about distributors or spark plugs. Regular maintenance, such as changing the oil, will help increase the life span of your engine. Diesel engines are more technologically advanced than gasoline engines. Only certified mechanics should service your engine.


3. Greater torque

Diesel engine emits more energy compared to gasoline engines. A diesel engine is the best if you are planning to get an engine that is strong enough to haul heavy loads or towing a trailer regularly because they have a greater amount of torque.

Trucks Regulations

What are the HVNL regulations?

HVNL means Heavy Vehicle National Law and they are a bunch of laws that apply to all vehicles that are 4.5 tons and above. Yes, that means it does not apply to all the vehicles that pass by the freeway. You must know what the weight of your vehicle is to know if you must follow those rules or not. The last thing you would want to happen is to get pulled over because of not following some simple rules. Also, they are not that hard to follow anyway so if you get caught not following the rules then you only have yourself to blame for that. There is a part of Australia that enforces the HVNL but not all of it does.


The HVNL is currently under review as the NTC described it as being too complicated to follow. It is a bit long as it currently stands at 676 pages. It also contains 5 regulations so it is something that should be taken seriously. If the HVNL is finally approved by the NTC, it will be enforced throughout Australia. The reason why State Road Regulators enforce the HVNL is that they are familiar with how important it is. They know how good it can be for people out there. They are also concerned with the safety of everyone involved. The last thing they would want to happen is for someone to get into an accident so they are thankful these laws exist.


What classifies as a heavy vehicle?

A vehicle that weighs at least 2.3 kg or 4.5 tons is considered a heavy vehicle immediately. It will be silly if you don’t know the weight of your vehicle. If you are caught not following simple HVNL regulations then you say you don’t know the weight of the vehicle then the police officer may think you stole it. Of course, you should not even think of worrying about the HVNL if you are driving a small vehicle. There is a completely different set of rules for that. Since the vehicle is pretty heavy, it would be virtually impossible for someone to lift it all by himself.


You will feel the difficulties of driving a heavy vehicle when you are used to driving a small vehicle. It is going to take some time to get used to it. If you are just new to it, you must not take it to the freeway yet or you may get into an accident. You must practice a little with it by using it at small roads with little to no vehicles. Once you get the hang of it, then that is when you can take it to the freeway. You will have a lot of fun running at high speed with it once you get comfortable with the controls.


What are the rules to be followed while using freeway for trucks?

One of the basic rules for heavy truck drivers would be to avoid texting while driving. If you need to know the directions to the place you are going to then you can ask the person sitting next to you to do that for you. That would be a lot better than doing it yourself. When you make a sharp curve, don’t forget to signal so the vehicle behind you will know what you are about to do. When the driver knows that, he will give you a lot of space. The driver knows it would not make sense to make a sharp turn at the same time as a heavy truck.


The truth is safe transportation should be practised no matter what the weight of your vehicle is. When you are driving, you can hurt yourself or you can hurt somebody else. Thus, you must always be careful and the first thing to remember would be to always fasten your seat belt. Besides, that rule is for your safety. If you are not wearing your seat belt, then you are making a big mistake. Another rule would be to never drive after having a few alcoholic drinks. No matter how confident you are about your tolerance to alcohol, this is something you should not even think of doing.
