Claas MERCATOR Parts Catalog – 168 Pages of Factory Part Numbers

You ever order a part for a Claas MERCATOR and get the wrong piece because the aftermarket catalog used a generic number? I’ve seen it cost a guy a full day of downtime, waiting on the correct replacement while the combine sits. This is the factory Parts Catalog – 168 pages of OEM part numbers, exploded diagrams, and cross-references. No guesswork. Every number traces back to the Claas engineering release.

Dividers and Cutter Bar – Sections 1-7

Part I of the catalog covers the header: rozdzielacze (dividers) and przyrząd żniwny (cutter bar). Page 3 gives a quick overview in seven languages – English, German, French, Danish, Swedish, Dutch, Italian, Spanish. Sections 1 through 7 break down every bracket, wear plate, and knife section. Page 4 shows the exact listing for the long divider group, including part numbers like 502606.0 (knebelmutter) and 610240.1 (halmteilerblech). If your MERCATOR is eating dividers, you need the factory numbers to get the right parts.

Threshing Mechanism – What Sections 18-23 Cover

Part II dives into the heart of the machine: bęben młócący (threshing drum), klepisko (concave), and odrzutnik (beater). Sections 18 and 19 list the drum assembly – bearings, bars, and rasp bars. Section 20-21 cover the concave segments and their bolts. Section 22-23 handle the beater. Without the correct part numbers, you might order a concave that doesn’t match the drum clearance adjustment slots. This catalog gives you the original Claas numbers so you can order the exact curved section your machine left the factory with.

7 Major Assembly Groups in the Catalog

The catalog is split into eight parts (Część I-VIII), but seven major groups: header, threshing, grain handling, operator platform, main drive, chassis, and hydraulics. Each group contains multiple sections – for example, Part III (Sections 30-35) covers the grain tank and elevators. Part IV (Sections 36-45) covers the operator platform, including the seat, controls, and cab panels. Part V (Sections 46-58) covers the main drive, ground drive, and rear axle. That structure means you can find the part number for a specific hydraulic cylinder or a steering tie rod without flipping through unrelated pages.

Use the Part Number Listings on Page 4 for Fast Ordering

Page 4 of the catalog is a perfect example of the format. It lists the long divider group, starting with part numbers, quantities per group, and descriptions in German. Every bolt, lock washer, and safety pin has a Claas part number. Need a replacement split pin for the divider? Section 1, item 1: 235090.0 – Splint 4×30 DIN 94. That number is what the dealer’s system expects. Don’t trust an aftermarket list that substitutes a generic fastener – use the OEM number and get the exact fit.

Hydraulic Components: Pump, Valve, and Cylinder Diagrams

Part VII (Sections 69-77) covers every hydraulic component. The pump (section 69), control valve (section 70), reel cylinder (section 71), cutter bar cylinder (section 72), steering cylinder (section 73), and all hydraulic lines (sections 74-77). If you’re rebuilding the cylinder or replacing a hose, the catalog shows the exact routing and part numbers for fittings, seals, and hose assemblies. That matters when you’re in the field and need to order a replacement before the rush of harvest.

Who Needs This Catalog?

DIY farmers, independent mechanics, and fleet owners who maintain Claas MERCATOR combines. You’re the one ordering parts, not the dealer. With this catalog, you can look up the part number for the straw walker arm (Sections 24-25) or the grain elevator chain (Sections 30-32) yourself, then match it against what’s in stock. It cuts out the back-and-forth with the parts counter. One guy I know spent two hours on the phone trying to identify a concaved segment – the dealer kept asking for a number he didn’t have. This catalog would have given him the answer in two minutes.

Why This Isn’t a Third-Party Compilation

The file is named Claas_MERCATOR_Parts_Catalog_en-fr-da-sv-20414001355.pdf – that’s the original factory release, not a scanned reprint of a reprint. Aftermarket catalogs often merge multiple model years or use superseded numbers. This one lists parts as they left the factory. The table of contents uses the original Polish/German section titles, and the part listings include the exact Claas part numbers. If you’ve ever been burned by a generic catalog that shows the wrong part for your serial number, you’ll appreciate the difference.

Does this catalog include part numbers for the Ford 2704E engine?

Yes, sections 78-86 cover engine accessories.

Can I use this catalog to order parts from any dealer?

Absolutely. The part numbers are Claas OEM numbers, identical to what the dealer system uses. However, always verify with your local dealer for supersessions, as Claas occasionally updates part numbers. This catalog is the original reference, so you’ll have the exact numbers to cross-check against current stock.

What languages are included?

English, French, German, Danish, Swedish, Dutch, Italian, Spanish.

How are the sections organized?

The catalog is divided into eight main parts (Część I-VIII) covering the entire combine. Each part groups related assemblies. For example, Part II covers the threshing system (drum, concave, straw walkers). The table of contents on page 3 gives an overview in multiple languages.

Stop wasting time with mismatched parts. Access the Factory Manual and get the exact part numbers Claas built into your MERCATOR.
