The Mercedes-Benz OM400 series, including the OM441, OM442, and OM443 engines, have been among the most reliable and widely used heavy-duty diesel engines worldwide for decades. Their reputation is based on robust engineering, ease of maintenance, and the ability to deliver consistent performance under harsh conditions..
Also the MTU 183, which is technically closely linked to Mercedes, is also considered worldwide to be a highly durable engine for professional applications, from naval units to military vehicles and industrial power plants.
As an international supplier of spare parts, we have been supporting operators, workshops, and dealers for many years with the supply, identification, and technical advice for these engines. We offer genuine, OEM, and high-quality aftermarket components and help you operate your engines reliably and economically.
Mercedes OM4xx-Serie
The Mercedes-Benz OM400 series has been among the most reliable heavy-duty diesel engines worldwide for decades. The OM441 (V8) and OM442 (V10) models, in particular, have established themselves as robust and durable engines, reliably performing their duties in generator sets, industrial applications, and heavy commercial vehicles. Both engines are known for their ease of maintenance, high load capacity, and long service life – provided they are supplied with the correct spare parts.
This is precisely where we come in: For the OM441 and OM442 engines, we supply original parts, OEM components, and high-quality aftermarket parts, depending on the customer's needs, budget, and application. Whether pistons and cylinder liners, gaskets, pumps, injection system components, or complete overhaul kits – we support operators with a fast and reliable parts supply and help identify the correct components.
Even many years after the end of production of the OM400 series, we ensure that the OM441 and OM442 continue to run reliably and economically. With our many years of experience and our extensive network, we are the right partner for a continuous and high-quality supply of spare parts for these proven Mercedes engines.

MTU 183
The MTU 183 is among the most robust diesel engines in its performance class – and its origins are no coincidence. Technically, the MTU 183 series is based on the proven Mercedes-Benz OM400/OM440 engine family, particularly on designs such as the Mercedes OM441 LA. MTU utilized Mercedes' solid basic architecture and developed a high-performance engine specifically designed for demanding applications in the marine, military, and industrial sectors.
This technical similarity is evident in both the design and the many components that are based on Mercedes design principles. For operators, this means one thing above all: excellent spare parts availability and long-term supply security.
We supply the appropriate spare parts for the MTU 183 – original, OEM or high-quality aftermarket parts – and support operators in keeping their systems reliable, economical and ready for long-term use.
Genuine, OEM or Aftermarket – wWhich option makes sense?
We actively advise our customers on which quality level suits their application profile:
-
Genuine: Maximum lifespan, highest precision fit
-
OEM: Genuine manufacturer parts, but without Mercedes/MTU branding
-
Aftermarket (Premium): For older engines or budget optimization
With over 20 years of experience in after-sales, we know exactly which variant proves its worth in which application.
