Internal Combustion Engines Mercedes-Benz

Mercedes-Benz isn't just known for legendary cars. It also makes trucks, buses, and heavy equipment. Diesel Mercedes engine units from the OM series go into trucks, construction gear, and industrial machines, where what matters most is steady work under load. In the RRF catalog, these engines are sorted by equipment type, from the small OM904 to the big OM502 used in the heaviest trucks.

RRF Construktion Solution offers Mercedes engine diesel units through the catalog in Dubai Silicon Oasis. Picking the right one starts with the machine's model, chassis number, and a power unit code. Even one Actros truck comes with several different options. If you don't know the code, just send a photo of the nameplate and the machine's serial number.

Mercedes-Benz Engine Lineup

The catalog has engines from different generations and sizes, from small industrial versions to the big truck series. To start looking, just type "Mercedes-Benz" into the search box, and it'll take you straight to the page with all their models. The motor code gives you a hint too. The higher the number in the model, the bigger the size and power.

Compact and Mid-Size OM Engines

The OM904 (4.2 L, 4 cylinders, 75–130 kW), OM924 (4.8 L), OM906 (6.4 L, 6 cylinders, 170–210 kW, 810–1150 Nm of torque), and OM926 (7.2 L) belong to this group. Nothing flashy here, just steady workhorses for mid-size construction gear, compressors, small generators, and buses running local routes.

The OM936 deserves a mention on its own: a 6-cylinder, 7.7-liter unit that ends up, among other places, under the hood of the Tourismo bus.

Heavy Engines for Trucks

Mercedes-Benz builds the OM470 to OM473 for heavy-duty jobs. The OM470 is 10.7 L and puts out 240 to 335 kW, with torque of 1800 Nm. The OM471 is bigger – 12.8 L, 310 to 390 kW, torque up to 2600 Nm. And the OM473 is the biggest of the three, at 15.6 L, with power up to 460 kW and torque up to 3000 Nm. These go into the Actros and Arocs, which are built to pull loads weighing up to 250–500 tonnes.

The Actros and Arocs are the best-selling trucks in the Middle East, so requests for a Mercedes-Benz engine for a truck from this series are among the most common in our catalog. To handle the heat and dust here, these trucks come with cyclone air filters that trap up to 80% of dust before it even reaches the main filter, plus transmission oil coolers built for extreme temperatures.

The Legendary OM366

The OM366 is a 6-cylinder engine introduced in 1983, about 6 liters, producing 100 to 150 kW of power. Used in trucks, buses, construction machines, industrial equipment, and generators.

Why so many? It is simple and tough. The turbo is light, and the whole engine weighs only about 450 kg – not much for this size. There is also a smaller version, the 4-cylinder OM364, made for machines where the full motor was too big.

V8 Versions and Heavy Stationary Units

Besides the inline six- and four-cylinder models, the lineup also has V8 versions – the OM501 and OM502, up to 16 liters. These go into the heaviest equipment and stationary industrial setups, where you need a lot of torque at fairly low RPMs. These aren't power units for everyday city driving. They're built for long, non-stop work under load.

Why the Production Year and Setup Matter

The same motor code can be made for years with small changes along the way: a different turbo, a different fuel injection setup, updated engine control electronics. That is why it helps to give the machine's production year along with the code. It lets the supplier rule out the wrong motor generation before even sending the request to the warehouse.

If you already know the code, using it is simple: type the code into the search box on the site (like "OM366") or find the matching card in the list of Mercedes-Benz models and click "Get information," which opens the page for that exact model. From there, add the machine's production year and serial number to your request, so the supplier can check that this is the right version.

Mercedes Engines for Special-Purpose Vehicles and Trucks

For trucks and specialized equipment, picking the right power unit usually comes down to the exact configuration of the machine, not just the brand. So it's best to start with the vehicle itself, the truck, crane, pump, or bus, and only then move on to the engine code.

Mercedes Engine for an Actros in Dubai

Need a Mercedes engine for an Actros truck in Dubai? First, check what trim your truck has – the Actros can come with the OM460, OM471, or OM473 depending on the version. To order, just give us:

• Truck model and axle setup
• Chassis number
• Year made
• Code of the engine on it now
• Engine serial number
• A photo of the nameplate

Mercedes-Benz says the heavy Actros runs on either a 12.8- or 15.6-liter motor, depends on the version.

Looking for Mercedes truck engines in general? The same info works fine – model, chassis, motor code, and serial number. Already took the old power unit out? Snap a photo of it before you do, or just photos of the mounts and connections. Helps a lot with older trucks where you can't find the paperwork.

Replacing an Engine on a Crane

A crane isn't just a vehicle. The engine is part of the whole working system, so a Mercedes replacement engine for a crane request should come with the crane's serial number plus photos of:

• Where the engine sits
• The mounts
• The hoses
• The exhaust
• The electrical connectors
• The factory nameplate

Take a request for a Mercedes OM460 engine for a Liebherr crane, for example. The code OM460 alone doesn't tell you which Liebherr model it fits: even if the engine name matches, the mounts, extra equipment, and control system can be different between crane generations.

Engine for a Concrete Pump

For a Mercedes diesel engine for a concrete pump, tell us the maker and model of the pump, the serial number, and info about the old motor. Photos help a lot here. They show not just the motor code, but how it's mounted in the pump's frame, which matters more for fit than the size or power.

A concrete pump usually works in short, hard bursts: full-load pumping concrete, then a break while it moves or waits. That's a different kind of load on the cooling system than a truck driving on the highway, so even a motor with the same code might have a different coolant pump setup.

Mercedes-Benz Engine for a Bus

Looking for a Mercedes-Benz replacement engine for bus? It all comes down to the exact bus model. Take the Mercedes-Benz Tourismo – it has the OM936 (7.7 L) or the OM470 (10.7 L), and power ranges anywhere from 260 kW (354 hp) up to 335 kW (456 hp).

So if you ask for a Mercedes Benz engine Tourismo bus without saying which trim, you might end up with an engine that just doesn't match – wrong power, wrong mounts. And if that bus is running a regular route, every day it's down costs money. Best to gather everything up front – model, chassis, and engine code before you even send the request.

Heavy Engine Swap in the UAE

Sometimes you need more than a simple “one-to-one” replacement. A Mercedes-Benz heavy engine swap in the UAE may also require changes to some mounts or connections. In this case, it is better to check the whole setup in advance: what machine is being used, what engine is installed now, and which model will replace it.

The heat and sand in the UAE can put extra load on the cooling system and air filter of any motor, whether it is used in a truck, crane, or concrete pump. That is why, during a heavy engine swap, it is worth checking the radiator and intercooler as well, not just the power unit itself. Otherwise, the new motor may need service more often than expected.

When to Consider a Different Mercedes Engine Version

Sometimes the exact replacement engine is not available, and the supplier may offer another version from the same series. For example, a different OM470 version with slightly different power. In this case, it is better to check not only the mounting size but also if the engine control system works with the machine’s electronics, because different versions may use different control units.

An older Euro III OM470 and a newer Euro V OM470 are a good case in point. Both put out roughly the same power, but they can use different wiring harnesses and control units.

Genuine Mercedes-Benz Power Units for Construction & Agriculture

Construction and agricultural equipment often works far from service centers – on a work site, in the field, or at an industrial site. So before ordering, check the model, motor size, power, mounts, cooling system, exhaust, and electronics, not just the code.

Industrial Equipment

Industrial machines can work for 8–12 hours a day without stopping. So for Mercedes industrial engines, it is important to give not only the equipment model but also how the machine works – all the time, with breaks, or with changing loads. This can affect the engine setup more than the equipment size itself.

The same applies to Mercedes power unit for industrial machinery. It is better to say if the engine will run non-stop or in cycles, because these are different cooling and lubrication conditions. For example, a compressor on a construction site that starts and stops several times during a shift needs a different start system setup than a stationary pump that runs all day and night.

Generator Sets

A generator works differently from a truck or a crane because the motor is connected to the generator unit. For a Mercedes-Benz diesel engine for generator, the request should include the generator model, power, serial number of the old motor, and a photo of the engine installation. If it is a replacement, also check the cooling system, exhaust, and connection to the generator.

Agricultural Machinery

Seasonal heavy workloads are recommended for agricultural machines. A search for a Mercedes OM366 engine for a Claas combine is a good example of how an old and reliable engine is still needed. The OM366 was used in older combine models because it is compact and has a simple design.

To find the right motor, provide the combine model, year of production, and serial number. Extra equipment can be different on different versions, even when they have the same engine code.

Marine Use

Mercedes marine diesel engines are different from truck engines. They have a different cooling system, exhaust system, and extra protection against corrosion. This makes them suitable for wet conditions.

These power units are used in small work boats and port equipment. Do not choose an engine only by the land code. You also need the boat or equipment model and the details of the equipment already installed.

Mercedes Engine Life and Maintenance Cost

OM engines usually have removable wet cylinder liners. This means you do not need to machine the whole engine block during a major repair. Only the liner and piston need to be replaced. This can save a lot of time and money compared with engines without this design.

For machines that cannot stay out of work for many days, this can make a big difference in cost. Regular oil and filter changes are not very expensive. But if you delay maintenance, the repair сost much more. That is why it is better to follow the service schedule instead of waiting until the engine has a problem.
