When a Baudouin diesel engine needs attention, the smartest first step is to open a baudouin engine parts catalog and match the failing component to the exact model. Baudouin engines drive generators, marine vessels, pumps and heavy machinery all over the world, and every model in the M Series family carries its own part numbers and specifications. A clear catalog removes the guesswork, so workshops, fleet owners and parts suppliers can order the right piston, liner, crankshaft or gasket on the first attempt.
EPID Diesel Engine Parts supports this process as a Chinese diesel engine parts exporter. We stock genuine and OEM-quality Baudouin and Weichai components for the 4M, 6M, 12M and 20M engine ranges. In this guide we explain how a Baudouin parts catalog is organized, how to locate parts by model, and where to buy the components you need with confidence.
Why a Baudouin Parts Catalog Matters
A parts catalog is more than a list of numbers. It is the reference that keeps a diesel engine serviceable over a long working life. Baudouin engines often run for tens of thousands of hours in demanding conditions, and small differences between models mean a part that fits a 6M26 will not always fit a 6M33 or a 12M26. Using the correct catalog prevents wrong orders, wasted freight and costly downtime.
The catalog also connects each component to its place in the engine, from the cylinder block and rotating assembly to the fuel and cooling systems. When you know the model and the engine group, you can move straight to the part you need instead of searching page by page. For high-value parts such as crankshafts and cylinder heads, that precision also protects your engine from mismatched aftermarket pieces.
How to Find Parts by Engine Model
Start by reading the engine data plate. It records the model, serial number and power rating, and it is usually fixed to the crankcase or the rocker cover. Write down the full model code, for example 6M21G, 12M26 or 20M33, because the suffix often describes the application, such as a generator drive or a marine rating. That one detail determines which pages of the catalog apply to your engine.
Next, locate the engine group you are servicing. The main groups in any baudouin engine parts catalog include:
- Cylinder block, liners and crankcase
- Pistons, rings and connecting rods
- Crankshaft, bearings and flywheel
- Cylinder head, valves and gaskets
- Fuel, cooling and turbocharger systems
Once you reach the right group, the catalog lists each part with its drawing reference and part number, which is the exact information a supplier needs. Matching the group and drawing reference to the part number is what turns a vague request into a precise order.
Key Components in the M Series Catalog
Baudouin M Series engines share a modular design, and many wear parts are common across the range. For a full rebuild, our Baudouin Weichai engine overhaul kits for M Series models bundle the gaskets, bearings and seals you need in one package, which saves time and keeps every part matched.
For cylinder work, a quality Baudouin cylinder liner for 4M, 6M, 12M and 20M engines restores the bore surface and protects ring sealing. If the rotating assembly is the problem, a genuine Baudouin M Series crankshaft brings the bottom end back to factory tolerance and keeps the engine balanced under load.
Tips for Ordering Genuine Baudouin Parts
Always confirm the part number against the engine data plate before ordering, and keep a photo of the old component if you can. Genuine and OEM-quality parts match the factory material and clearances, which matters most in a diesel engine that runs at high temperature and pressure. Working with a supplier that understands the M Series range also saves time, because they can cross-check the number for you and flag any part that has been superseded.
Frequently Asked Questions
How do I identify my Baudouin engine model?
Read the engine data plate, usually mounted on the crankcase or rocker cover. It shows the model code, serial number and application, which are the details every parts search should start from.

Yes. EPID Diesel Engine Parts supplies complete Baudouin Weichai engine overhaul kits that cover the main wear items for a rebuild, so you receive matched components in one order.
Are parts available for older Baudouin models?
In most cases, yes. Our team can source parts for older 4M, 6M and 12M engines as well as current production, using your model and part number to confirm availability before shipping.
