What the Baudouin 4M06G is used for

The 4M06G family powers small generator sets and marine auxiliaries. Baudouin engines are used almost exclusively in generator sets and marine applications, so kits and cylinder unit parts are the fastest-moving items. Because these engines work long hours in dusty or hot conditions, the wear parts - cylinder kits, bearings and sealing - are replaced on a schedule rather than when they fail.

We ship Baudouin 4M06G parts to France, Belgium, North and West Africa and the Middle East, usually for fleets, engine rebuilders and generator service companies. Most orders combine several component groups in one shipment, which is why quoting by part number matters: it is the only way to be sure two suppliers are quoting the same part.

How to identify your 4M06G variant

Two Baudouin 4M06G engines of the same nominal model can use different pistons, liners or head gaskets depending on build year and rating. Before ordering, take three pieces of information from the engine:

  1. The engine plate. Model, serial number and power rating are stamped on the plate; photograph it.
  2. The OEM number on the old part. Even a worn part carries the number, usually on the casting or a machined face.
  3. The application. A 4M06G in a generator set is often rated differently from the same engine in a truck, and the cooling and fuel components differ.

If you only have the serial number, send it to us - we identify the correct numbers from the parts list and confirm before you pay.

4M06G part numbers and cross reference

Buyers increasingly search by number rather than by description, and for good reason: 4M06G parts are shared across several ratings and the number is the only unambiguous identifier. Our Baudouin directory lists the numbers we publish, each linked to photos and specifications.

  3. Quantity - single pieces and sample orders are welcome
  4. Quality grade: genuine, OEM-grade or aftermarket
  5. Destination port or airport so we can quote FOB, CIF or DDP
