Used Benz Diesel Generators
Mercedes-Benz and MTU engines appear in European-built generating sets and are among the longest-lived diesels in the used market. They are also the machines where documentation matters most, because the parts are priced accordingly.
Our Benz stock is a small line of European-built sets in the mid to large ratings, mostly in silent canopies. These are machines bought by projects that value a long service life and a documented history over the lowest purchase price.
Available units

5 individual used sets are listed below. Each one is photographed where it stands and carries its own parameter table. Ratings are prime power in kVA at 0.8 power factor.

Brand notes
Benz in a used set
| Item | Detail |
|---|---|
| Origin | Mercedes-Benz and MTU, Germany |
| Engine families seen in this stock | Mercedes-Benz OM series industrial diesels, and MTU units in the heaviest sets |
| Alternator pairings | Usually Stamford or Leroy-Somer; quoted from the nameplate on each machine |
| Parts | Available through the Mercedes-Benz industrial and MTU networks; the parts are priced as premium components, so a set with service records is worth more than an equivalent machine without them |
| What the brand does not tell you | That a Mercedes badge on the canopy means a Mercedes engine, and that the parts will be cheap. Neither is true of the used market. The engine plate and the documentation decide what the machine is |
Requirements
What to check on a used Benz set
| Item | What we check | Why it matters |
|---|---|---|
| Engine hours and the hour meter itself | The reading, and whether it agrees with the service records | An hour meter is the easiest thing on a set to replace, and the hardest to verify afterwards |
| Engine make and model | The plate on the block, not the badge on the canopy | On a used set the engine is the value; the canopy is sheet metal |
| Serial number and build year | Read from the block and checked against the documentation | It fixes which revision of the engine you are buying parts for |
| Oil pressure and blow-by | Hot idle oil pressure, and the crankcase breather with the engine running | Together they say more about bore and ring condition than any other two checks |
| Coolant and oil condition | Colour, level, and whether there is fuel or combustion gas in the coolant | Contamination is a sign of a head gasket or a liner problem rather than routine wear |
| Alternator | Make and model, insulation resistance, and a visual check of the windings | The alternator is the second most valuable item, and moisture damage hides until it is loaded |
| Control panel | Model, firmware, and whether the protection settings can be read and changed | A panel that cannot be configured is a panel that will be replaced |
| Load test | Load bank run at 100%, 75% and 50%, with the figures recorded | A set that starts and idles proves very little about a set that has to carry a load |
| Corrosion and enclosure | Seams, fasteners, base frame and the radiator core | On a coastal or island site this is the difference between a repaint and a rebuild |
Questions
Questions we are asked about Benz sets
Why does the badge on the canopy not settle which engine is inside?
Because used sets are re-canopied, re-badged and re-painted as they move between owners and markets. Two machines that both read Benz on the side can carry different engine families, different alternators and control panels from different decades. The plate on the engine block and the alternator nameplate are what the quotation is actually about.
How are these sets rated?
Ratings are quoted as prime power in kVA at 0.8 power factor, with the standby figure given where the set and its documentation support one. Prime and standby are two different ratings of the same machine, and a set that has run for years as prime power should not be re-labelled as standby without an inspection.
What is included with a set bought here?
The set as photographed, its parameter table, the load test figures where they exist, and the documentation we hold
Can the set be re-wound or re-configured for another voltage or frequency?
Voltage changes are usually a reconnection of the alternator and are quoted per machine. Frequency is not: a 50 Hz set runs at 1500 rpm and a 60 Hz set at 1800 rpm, and the engine, the radiator and the alternator rating all differ. If a project needs the other frequency, the right answer is another machine rather than a conversion.
Who services a used Benz set in Southeast Asia?
Through the Mercedes-Benz industrial and MTU networks, or by a specialist workshop the buyer nominates
