Sennebogen 840 Parts Catalog – Factory Spare Parts List (666 Pages)

You’ve got a Sennebogen 840 on the job site and something broke. Without the right part number, you either order the wrong hydraulic fitting or waste hours cross-referencing aftermarket catalogs. This Parts Catalog is the factory-issued document from Sennebogen Maschinenfabrik GmbH. It’s not a reprint or a third-party compilation. It’s the same 666-page binder the dealer’s parts counter uses. If you need the order number for a boom cylinder seal kit or the inspection set breakdown, this is the only source you can trust.

The manual is structured so the left-hand page shows the component drawing with order numbers, and the right-hand page lists the item number, ident number, nomenclature, quantity, and MPOS remark. Page information and serial number of the machine are included. No guessing which O-ring fits where.

What You Get in This 666-Page Parts Catalog

The document opens with a “Machine Overview” that breaks the Sennebogen 840 into module sections: 100–199 for the undercarriage, 300–399 for the superstructure, 500–599 for equipment, etc. Each module gets its own parts list. You also get the “Inspection Set” and “Gas Filled Spring Overview” near the front — critical when you’re replacing cylinders or checking safety accumulators. The catalog ends with two indices: one sorted by module and one by order number. Finding a part takes minutes, not hours.

Machine Overview and Module Breakdown

Page 3 of the Automotive Industry Overview part is about understanding how the ETK (Ersatzteilkatalog) is laid out. The machine overview shows which module sections contain which components. For example, the undercarriage is section 100–199, the equipment section is 500–599. The table of contents on the opposite page lists modules, not all, but the ones you’ll need for ordering. If you see a page reference in the parts list (right column), that takes you to the drawing of the sub-assembly. This is how factory manuals avoid redundancy — every part number appears exactly once.

Is This a Service Manual or a Parts List?

This is a Parts Catalog, not a service manual. You won’t find torque specs or step-by-step removal procedures here. What you do get is the exact OEM part number for every replaceable component on the Sennebogen 840. The drawings are for identification only — don’t use them as assembly instructions. If you need repair procedures, pair this catalog with the matching service manual. But for ordering parts, this is the only document that matters. The copyright notice on page 2 says reproduction only with written permission from Sennebogen Maschinenfabrik GmbH. That’s how you know it’s genuine.

Using the Inspection Set and Gas-Filled Spring Overview

Look at the “Contents” page in the Information chapter. Right after the general info, you’ll find the “inspection set” and the “gas filled spring overview”. These sections are separate from the main parts list because they cover items that are often replaced as sets. The gas filled spring overview lists accumulators and gas springs by model variant. The inspection set gives you a kit of seals and wear parts. When you’re overhauling a cylinder, order the inspection set instead of hunting individual seals — it’s the factory-recommended kit.

How to Read the Parts List Drawings and Item Numbers

The left-hand page shows a line drawing with order numbers. The right-hand page is a table with columns: Item (position number), Ident (order number), Nomenclature (part name), Qty, MPOS remark, and Page reference. Item numbers that are struck through (e.g., 418634/) mean that part cannot be ordered individually — you must order the complete assembly. Look for the asterisk (*) next to the order number; that means the part can be ordered. The MPOS remark links the part to the electrical or hydraulic diagram if applicable. You have to read these columns carefully; a mistake in the ident number will get you the wrong threaded fitting.

The Automotive Industry Overview also covers why OEM documentation matters for construction equipment safety and reliability.

Does this parts catalog include torque specifications or repair instructions?

No. This is strictly a parts list. It contains drawings, order numbers, and quantities for the Sennebogen 840. For service procedures you need the factory service manual.

Can I use this catalog for a Sennebogen 840 built after 2010?

This catalog is from a 2010 production run (project 840.5.1017). It covers the specific machine series listed on the first page. If your machine has a later serial number, the part numbers may have superseded items. Always verify with the current Sennebogen dealer, but this is the closest OEM document to the original build. The inspection set and gas spring overview are especially useful because those components change slowly.

If you’re tired of chasing wrong part numbers and paying restocking fees, get the official document. Access the Factory Manual and start ordering the right parts tomorrow.
