Claas MERCATOR S, MERCATOR 70, MERCATOR 75 Parts Catalog

Every time a combine sits because someone ordered the wrong seal or bearing, that’s money burned. I’ve watched guys pull a threshing drum and then spend an hour on the phone because they didn’t have the right part number. This Claas MERCATOR S, MERCATOR 70, MERCATOR 75 Parts Catalog is the only way to get the factory part code the first time. None of those aftermarket cross-reference lists that guess at which bushing fits. This is the same binder the dealer parts counter uses – 229 pages of exploded diagrams and exact Claas part numbers for all three models.

Schneidwerk and Haspel: Identifying Cutter Bar and Reel Parts

Look at the TOC. Sections 3 through 7 cover the Schneidwerk (cutter bar). You get every blade, guard, ledger plate, and drive component broken out by illustration. Each part has a unique Claas number – no vague descriptions like “knife section.” Need a reel slat bearing? That’s in the Haspel sections (10–15). You’ll see the part number for the bearing, the bolt, even the split pin. If you’re rebuilding a pickup reel, this catalog saves you from ordering a whole assembly when all you need is a bushing. I’ve had guys tell me they used this to find a $3 part instead of a $300 reel. That’s why you buy factory.

Does This Catalog Cover All MERCATOR Variants?

Yes – MERCATOR S, MERCATOR 70, and MERCATOR 75. The catalog groups parts by model where they differ. For example, the engine sections (Ford, Perkins, Deutz, Mercedes) are all included – pages 79–85 for Ford, 86–92 for Perkins, 150–163 for Deutz and Mercedes. Each engine gets its own part breakdown. If you’re working on a MERCATOR 75 with a Mercedes power plant, the catalog has the injector lines, gaskets, and seals. No need to hunt down a separate engine manual for part numbers – it’s all here.

10 Sections for the Threshing Mechanism Alone

The threshing area – Dreschtrommel, Dreschkorb, Wendetrommel, Schüttler, Siebenkasten – runs from section 18 through 28. That’s ten separate groups covering the drum, concave, beater, straw walkers, and sieves. Each grouping shows the assembly exploded, with every spring, rubber mount, and screen panel called out by part number. I’ve had to replace walker bushings on a MERCATOR 70; without this catalog you’re measuring old bushings and guessing. With it, you order Claas 610249.0 or whatever the number is and it fits. Period.

Use the Factory Part Number, Not a Cross-Reference

Aftermarket parts catalogs will tell you a “universal” bearing fits the MERCATOR 75. Then you install it and the shaft wobbles because the snap ring groove is off by a millimeter. This catalog gives you the OEM part number that Claas stamped on the original component. You take that number to your dealer or supplier and get the real thing. Cross-referencing is a guess – factory documentation is a fact. I learned that twenty-eight years ago when I ruined a hydraulic cylinder because I used a generic seal. Don’t repeat my mistake.

Hydraulic Cylinder Parts: Controlled by OEM Specs

Sections 69 through 78 cover all hydraulics – pump, control valves, and cylinders for reel, cutter bar, steering. Every cylinder is broken into individual seals, rods, and pistons. Need a seal kit for the Schneidwerkzylinder? The part number is listed right next to the exploded view. No need to pull the cylinder and measure bore/stroke – just look up the model and section. I’ve seen shops charge an hour of labor just to measure a cylinder for seal identification. That’s wasted time when you own this catalog.

229 Pages: Every Exploded Diagram and Part Code

The entire document is 229 pages of OEM illustrations, with part numbers listed in a table format that includes the figure number, part number, description, quantity per group, and any notes (e.g., “ab Schneidwerk Nr. 225906” – from cutter bar serial number). It’s multi-language, but the part numbers are universal. Whether you read Polish, German, English, or French, the number is the same. I keep a copy on my tablet in the shop. Need a divider point? Check section 1 – it’s there. Grain tank auger? Sections 32–34B. Operator platform parts? Sections 35–45. Everything is indexed.

If you’re also working on other Claas models, check the Claas Columbus Parts Catalog – 82 Pages of OEM Part Numbers for the smaller combine, or the Claas M66 Parts Catalog – 107 Pages of OEM Part Numbers for the M66. The CLAAS Combine Harvester and Forager Parts Catalog covers additional machines. For background on agricultural machinery documentation, see Automotive Industry Overview.

Can I use this parts catalog for a MERCATOR 70 with a Perkins engine?

Yes. The catalog includes separate sections for Ford, Perkins, Deutz, and Mercedes engines. Find the engine group starting on page 86 (Perkins).

What if I need a part that crosses multiple sections, like a hydraulic hose that goes from the steering cylinder to the main valve?

Each section lists the cylinder and valve components separately, but the hose assemblies are in the Hydraulikleitungen groups (75–77). You’ll need to identify which hose by the routing diagram. The exploded views show the hose shape and fitting ends. If you can’t find the exact hose, look up the cylinder port size in section 74 then the valve port in section 70 – that gives you the thread dimensions to order a custom hose if the original is obsolete. The catalog doesn’t provide assembly routing, but the part numbers for the OEM hose are listed. If the part is discontinued, you can cross the fitting dimensions to a hydraulic shop.

Look, I’ve rebuilt dozens of these combines. The difference between a quick turnaround and a week of downtime is having the right part number in your hand before you disassemble. This catalog gives you that number. Access the Factory Manual and keep it on your bench. Your combine – and your wallet – will thank you.
