Excavator turbocharger

Complete, new and ready to bolt on, this is the replacement turbo for Cummins M11 diesel engines — the part to reach for when a machine has lost boost, when the old turbo has started passing oil, or when an engine is already stripped for a rebuild. As a diesel parts supplier we keep it as a turbocharger supplied in single pieces as well as in overhaul stock, so a workshop does not have to buy three to fix one machine. Typical buyers are excavator repair shops, mining and quarry maintenance teams, engine rebuild benches and parts counters that prefer to have an M11 unit on the shelf.

Each turbocharger assembly is balanced as a rotating group before it goes into the housing, and the turbine housing is built to take the exhaust heat an M11 produces on a long shift. A high-strength compressor wheel and premium bearings hold the shaft steady at speed, while the sealing components are chosen to keep oil where it belongs instead of letting it pass into the intake. What that gives the operator is quick spool-up from low engine speed, boost that stays steady through a full day rather than fading as the unit heats up, and less vibration through the housing. Cleaner combustion brings torque back, helps fuel economy recover and takes load off the rest of the engine — which is what matters when a machine is expected to keep working at this rating.
Our technical team supports buyers before and after the order. Send us your OEM part number or machine and engine details and we will confirm the correct match for your repair, overhaul or replacement job. If you are unsure what has failed, share the symptoms and our specialists will help with troubleshooting and narrow down the right assembly. We also provide installation and commissioning guidance, and share product documentation on request. With coverage across Komatsu, Caterpillar, Cummins, Isuzu, Hitachi, Sany, Doosan and Kubota machinery, we can help consolidate your parts requirements into one order.
This diesel turbocharger is built for the Cummins M11 family and replaces the original Holset unit on those engines. The M11 was offered in several ratings and went into everything from excavators to generator sets, so the number on your old unit is a safer match than the machine model alone. If the data plate has worn away, a photo of the housing and the oil feed flange is usually enough for us to identify it.
A drop in power, more exhaust smoke than the engine used to make, oil appearing in the intake pipework, and a whine or siren sound that rises and falls with engine speed are the usual clues. On an excavator the first symptom is often slower hydraulics, because the pump cannot get the power it was sized for. Any of these is worth investigating before the failure damages the engine.
Yes. It is supplied as a complete turbocharger assembly rather than a bare housing or a cartridge on its own, so the rotor, bearings and seals arrive matched to one another. The workshop fits one part and does not have to move internals across from the old unit, which also removes the risk of reusing a worn housing or a tired seal.
Both. On a planned M11 rebuild the turbo is renewed along with the rest of the top end, and after an unplanned failure it is the part that gets the machine back to work. As an engine parts supplier we treat it as a routine service item rather than a special order.
Keep it in its carton until the engine is ready to take it, and store it somewhere dry and away from grinding, welding or machining areas. A turbo that has been sitting open on a bench picks up grit and swarf, and that is one of the common reasons a new unit fails early. Leave any protective covers in place until the last moment.
Plan on fresh engine oil and an oil filter, plus the mounting and drain gaskets, which are rarely reusable. If the old unit failed dirty, the charge pipes and intercooler are worth cleaning out while everything is apart. On an M11 these are ordinary service items, and having them on the bench is usually what decides whether the machine goes back to work the same day.
