Schaeff HR20 Parts Catalog – Factory Parts Breakdown for Crawler Excavator

I’ve been turning wrenches long enough to know what happens when you order parts by eyeballing a worn-out bolt instead of looking up the factory number. You get the wrong thread pitch, wrong length, wrong everything, and the machine sits while you wait for the right part to show up. This Schaeff HR20 Parts Catalog is the fix for that. It’s 240 pages of exploded diagrams, group assemblies, and factory part numbers – no aftermarket cross-references, no reprints from somebody’s scanner. Just the original Schaeff documentation for the HR20 crawler excavator.

240 Pages of Factory Group Breakdowns

The catalog is organized by assembly groups. The OCR from the first page shows Group 1.001 – UNTERWAGEN, FRONT RÄUMSCHILD (undercarriage with front dozer blade). Each part gets its own line: item number, Schaeff part number, description, quantity, unit, and a reference to the drawing and sheet number. On page 1 you’ll find the dozer blade pin (part 0183502026), the M10x80 bolt (1008707225), the neoprene strip (5354640110), and the spacer bushing (0156001055). That level of detail runs through all 240 pages.

Part Numbers You Can Trust – Not Aftermarket Cross-References

This is an OEM print from Schaeff. The part numbers in this catalog are what the factory stamped on the engineering drawing. If you call a dealer with part 5609661462 (slew ring on page 4), they’ll pull up that exact number. Third-party catalogs often substitute “equivalent” numbers that may be close but not correct. Close doesn’t work on a swing bearing. The factory spec is the only spec that matters when you’re reassembling a 10-ton machine.

What’s Inside: Group 1.001 Undercarriage and Dozer Blade

Page 1 lists 18 parts for the undercarriage and dozer blade. You’ll see the grease nipple M10x1x90° (1609003010), bolts in M8x20 and M10x40 and M10x80, washers 8.4mm, and a hose clamp 140-160mm. The drawing on page 3 (Bildtafel 1.001) shows exactly where each part goes. That diagram saves you from pulling the wrong bolt out of a bin because you thought it looked right. If you need to rebuild the front blade assembly, this catalog gives you every piece, down to the neoprene strip.

Why a Parts Catalog Beats a General Service Manual for Ordering

Service manuals are great for procedures – torque sequences, fluid capacities, adjustment steps. But they rarely list every individual fastener and seal. This is a parts catalog. It exists solely to tell you what piece goes where and what number to order. If you’re trying to identify a worn bearing or a missing bolt, the exploded view and part number list are faster and more accurate than flipping through a service manual’s specifications section. Keep both documents on the bench, but start with this catalog when you’re ordering.

Who Needs This Catalog?

If you own an HR20, work on them at a rental yard, or run a shop that services crawler excavators, this catalog pays for itself the first time you avoid a wrong part. Beginners will appreciate the clear diagrams and English part descriptions (alongside German and French). Professionals will appreciate the factory‑accurate numbers that eliminate phone calls to the dealer.

Guessing part numbers costs money.

The automotive industry has standardized parts numbering systems – you can read about it on Automotive Industry Overview. But Schaeff’s numbering is unique to their platforms, and Automotive Industry Overview only gives you background; for the HR20 you need this catalog.

Don’t limit yourself to one model. If you also work on the Terex Schaeff SKL 871 1997 Parts Catalog – OEM Factory Manual or the Terex Schaeff SKL 861 1997 Parts Catalog – Factory OEM, those catalogs follow the same factory structure. The Terex Schaeff SKL 861 1994 Parts Catalog – OEM Specs covers an earlier variant. All of them are OEM prints, no third-party noise.

Frequently Asked Questions

Does this catalog include torque specifications?

No. It’s a parts catalog, not a service manual. You get part numbers, quantities, and exploded views – not tightening torques or repair procedures.

Can I use this to identify parts if I only have a serial number?

Possibly. The catalog groups parts by assembly (group number) and lists drawing sheets. If your machine falls within the HR20 model range, you can cross‑reference the group structure. There’s no serial number index in this document, but the drawings and part numbers remain consistent across production years unless a revision was issued. Check the sheet number on the diagram – that tells you which revision level applies.

Is this the same as the official Schaeff parts book?

Yes. This is a direct scan of the original Schaeff printed parts catalog. The file name confirms it’s from their own distribution. No reprints, no aftermarket compilation.

How do I read the group numbers in this catalog?

Each group number has four digits: major group (1 = undercarriage/attachment), decimal (001 = specific assembly). The drawing number references a separate illustration sheet. Pos. Nr. is the callout number in that illustration. Always match the Ident Nr. (part number) before ordering – the Pos. Nr. changes between revisions.
