Schaeff HR 31 2002 Parts Catalog

Let me tell you straight: if you’re working on a Schaeff HR 31 2002 Parts Catalog crawler excavator and you’re using some cut-rate aftermarket parts list, you’re asking for trouble. I’ve seen guys order the wrong hydraulic pump seal because their third-party catalog used a generic drawing. That’s a half-day job down the drain and a pissed-off customer. This is the real factory parts catalog – 376 pages of exploded diagrams, OEM part numbers, and cross-references for the HR 31. It’s printed by Schaeff-Terex themselves, and it covers serial numbers 033/2122 through 2266 from the 2002 edition. If you need to know which O-ring goes on that boom cylinder or which track roller assembly is correct for your machine, this is where you look.

3 Languages, One Parts Catalog – No Translation Guesswork

This catalog is laid out in German, English, and French. Every heading, every note, every part description appears in all three languages. Page 0.000 shows the Vorwort / Preamble / Introduction. Page 0.001 gives the Benutzerführung / Guide for user / Mode d’emploi – that’s where they explain how to navigate the subassembly groups. You don’t need to be a linguist; just find your language column and read across. For a shop that handles multiple operators, that’s a timesaver.

Baugruppen System – How to Find Parts by Subassembly

The catalog is broken into Hauptgruppen (main groups) and Baugruppen (subassemblies). Page 0.003 lists all the Baugruppen; page 0.004 gives a table of contents by group. For example, if you need parts for the oil tank, the example in the manual shows: first locate main group 4.000 “Rear chassis including mountings”, then go to subassembly 4.002 for the oil tank. The exploded view drawings show each component with an item number that matches the parts list. No guesswork – just follow the numbering.

Serial Number Verification – Why the Range Matters

Look at the front matter: this edition is valid from Fz-Id.Nr. 033/2122 to 2266. If your HR 31 falls outside that range, some parts may differ. Schaeff made running changes, and the parts catalog reflects that with legend symbols (> xxx/xxxx = from s/n; > xxx/xxxx = to s/n). Never order parts without checking your machine’s serial number first. I’ve seen a guy install a final drive that was one tooth off on the planetary gear because he ignored the serial break. That’s a two-shift repair you don’t want.

Wichtige Hinweise – Safety and Modification Notes

Section 0.002 is the Important Notice. It states that pictures are not binding for final execution and that Schaeff reserves the right to make modifications due to technical development. Translation: keep your parts catalog current if your machine has been updated. This manual is the 2002 edition, so it captures the factory baseline for that production window. If you need later updates, check Schaeff’s service bulletins or look at related manuals like Terex Schaeff SKL 871 1997 Parts Catalog – OEM Factory Manual or Terex Schaeff SKL 861 1997 Parts Catalog – Factory OEM. For the SKL 861 variant, Terex Schaeff SKL 861 1994 Parts Catalog – OEM Specs may also be useful.

Inhaltsverzeichnis nach Alphabet – The Quick Search Method

Page 0.005 gives an alphabetical index in three languages. If you know the part name but not the group number, look it up here. The index lists components like “Öltank / Oil tank / Réservoir hydraulique” and gives the corresponding Baugruppe number (e.g., 4.002). Then flip to that group page and find the exact item. The catalog’s 376 pages cover everything from bucket teeth to cab glass. No skips, no generic drawings – just factory part numbers.

Does This Parts Catalog Include Repair Procedures?

No. This is a parts catalog, not a service or repair manual. It will not tell you how to disassemble the hydraulic pump or torque the track tension bolts. For that, you need a separate service manual. But without this catalog, you’ll spend hours cross-referencing obsolete numbers or ordering the wrong piece. If you’re new to heavy equipment repair, reading up on general machinery standards can help: see Automotive Industry Overview for basic context, but remember that construction gear has its own specific norms. Also check Automotive Industry Overview for more background on industrial part numbering systems – it’s not a replacement for this catalog, but good foundational knowledge.

Tool and Material Requirements

What do you need to use this catalog? A clear workbench, good lighting, and your machine’s serial number. Also have a paper or digital copy of the index pages handy. No special tools needed – just the ability to read exploded views and match numbers. If you’re ordering parts, make sure you have the correct seven-digit Schaeff part number (e.g., 6 205 132 031 shown on page 3). Write it down exactly: one wrong digit and you get the wrong part.
