About Our Diesel Engine Repair & Overhaul Services

The Service Company has 3 locations in Ohio and offers a complete diesel engine solution for your heavy-duty truck. You’ll be able to identify that it’s time your engine needs some maintenance if you start to hear knocking sounds, if it’s running rough or not firing at all.  When you bring your heavy-duty truck to any of The Service Company’s locations, you can trust that our skilled technicians will use our sophisticated diagnostic software to find the cause of your problem and come up with an appropriate repair solution. 

How to Identify If Your Diesel Engine Needs Repair

An engine overhaul is a major diesel engine repair where the entire engine is rebuilt. During the overhaul, all components (bearings, pistons/liners, cylinder head, turbo and injectors) are inspected to ensure they are within the manufacturer's tolerance. Any parts that fall outside of those tolerances are replaced.  During disassembly, the engine is cleaned thoroughly to remove built-up grime and debris. Since your entire engine is being taken apart, it’s much easier for our mechanic to identify problems and replace malfunctioning parts. Once everything has been cleaned and the necessary replacements have been made, the engine will be put back together and set back into the truck.

There are two types of overhaul:

In-Frame: where the repair is done with the engine in the chassis

Out-of-Frame: where the engine is fully removed from the vehicle for repair.

If you notice any of these problems, it is time to bring your heavy-duty truck in to get overhauled or repaired  immediately:

  • Your engine has spun a rod bearing. This is one of the worst failures that can occur inside your diesel engine.
  • Your engine has very low or no oil pressure. This could be due to rod or main bearing wear.   A fuel or coolant leak can also contaminate the engine oil, which could lead to high oil level in the crankcase.
  • Excessive oil consumption. This is a leading indicator of internal engine wear.
  • Excessive blow-by.  This happens when the piston rings are worn, causing the engine compression to escape past the piston and fill the crankcase with excessive pressure.
  • Your engine has dropped a valve. This is an all too common and critical fault of a diesel engine.

Additional Truck Repair Services

Transmission & Clutch Repair

Correctly diagnosing and repairing transmission issues requires experience and the right tools. Most transmissions in today's commercial trucks have electronic modules to help with efficiency and performance. If you are experiencing transmission drivability issues, you can often avoid rebuilding the entire transmission by correctly diagnosing what is causing the issue. Count on us for your transmission & clutch repair needs.

Tire Repair

Flat tires can be a serious interruption to your work, but more importantly, a flat tire can be a serious threat to your safety on the road. Unfortunately, fixing a flat or servicing an old tire is just part of life on the road. The Service Company can help determine the best approach to either repairing or replacing your tires. We have the capability and inventory to help with most truck tire needs.

Suspension Repair

Your heavy-duty truck’s suspension system helps your wheels to remain in even contact with the road, smooth over potholes, rough roads, or off-road terrain so that you can brake, steer, and safely control your vehicle. The suspension system provides your vehicle with a cushion against the shock and impact of the road surface. A suspension system that functions correctly helps stabilize your truck, smooths the ride, and maintains the proper axle spacing and alignment. Our team can maintain your vehicle’s suspension.

Oil & Fluid

The key to keeping your heavy-duty truck running at its peak performance is proper maintenance. One of the essentials for ensuring the longevity of your truck is regular oil changes and fluid checks. Proper lubrication of your truck’s moving components is crucial for your engine to run correctly and to promote its longevity. Trust our team for all your oil & fluid needs.

HVAC System Repair

Are you noticing that your truck’s struggling to manage heating, cooling or ventilation? Whatever the weather, we’ve got you covered. Our technicians recognize that there are many possible issues that can arise with a heavy-duty truck’s HVAC system, and these can often be challenging to diagnose. Using industry-advanced technology, our team of trained mechanics can quickly and accurately identify your HVAC system issues before making any repairs or recommendations. We aim to cure the issue and not just patch the symptom.

Exhaust System Repair

A good truck exhaust service includes a proper maintenance schedule and regular inspection of the exhaust system. Our professional experts are available for consultations and information at any time.

Express Lube

To ensure your vehicle is running safely and efficiently, proper maintenance is crucial. This includes regular visits to our express oil and lube shop. When you stay on top of your truck’s lube and oil changes, your vehicle components have the necessary protection to keep running properly. This results in your truck lasting longer, driving smoother, having better fuel economy and it saves you money in extensive repairs down the road.

Engine Repair & Overhaul

At The Service Company, our facilities are equipped to overhaul or repair all types of ageing diesel engines. From headgasket replacement to a complete engine overhaul, our team will work with you to find the best solution for your needs and budget.

EGR & DPF

The EGR and DPF system in your heavy-duty truck work together as part of your emissions system to limit the output of harmful exhaust.

Driveline Repair

Your heavy-duty truck’s driveline is an essential part of your truck’s controls. It connects the transmission to the axles and transfers the power from the engine to the wheels. At The Service Company, we can handle all of your driveline maintenance and repairs requirements and get you back on the road, moving in the right direction.

DOT Inspection

DOT inspections are required by the US Department of Transportation and can include vehicle, load, driver and documentation assessments. They are performed on all commercial vehicles that weigh over 10,000 pounds.

Diagnostics & Electrical Repair

Modern diesel engines are more intricate than ever, and while they are remarkably dependable, they do require regular maintenance and service to ensure prime performance. When your truck develops an issue, you need it diagnosed, serviced and repaired quickly so you can get back on the road and back to work.

Coolant System Repair

One of the primary functions of coolant is to regulate heat within the cylinder head and engine block. The coolant system is designed to circulate a cooling medium which absorbs heat from the engine and dissipates it through a heat exchanger (i.e., a radiator or cooler).

Brake Repair

Your brake system involves many different components, and each one has to function correctly to keep you and others safe. Operators know without a doubt that your truck’s brakes are a key component that should never be overlooked. Worn brakes can make it difficult to slow, turn, stop and control your vehicle.‍ At The Service Company, our technicians are here to make sure you can always rely on your vehicle’s brakes.
