Schaeff HR 26 1983 Parts Catalog – Factory OEM Parts Breakdown

If you are trying to keep a Schaeff HR 26 1983 Parts Catalog crawler excavator running without the factory parts book, you are working blind. I have seen too many guys order a seal kit that doesn’t fit, waste three days waiting for the wrong part, then blame the machine. This catalog is 244 pages of what Schaeff actually bolted on. It covers the HR 26 series D, serial numbers 033/1250 to 033/1564. Published in 1983, it’s the original German-English-French edition. No reprints, no third-party redraws. You get the exact exploded views and part numbers that Schaeff-Terex GmbH used on the assembly line.

Every section in this catalog was printed from the same plates that went to dealers. The undercarriage, the boom, the swing drive – all broken down into individual components with corresponding part numbers. Need to order a track tensioner for the Leitradfederung? Page 3 gives you the idler travel assembly. Want the right seal for the swing brake actuator? Page 16 (Betätigung – Schwenkbremse) shows the exact parts. No guesswork, no cross-referencing aftermarket books that drop digits.

What the Table of Contents Tells You

The TOC is laid out in three languages: German, English, French. That alone saves you from translating foreign manuals. Sections range from Werkzeug und Zubehör (Tools and accessories) on page 1, through Unterwagen (Under carriage) page 2, all the way to Schwenkantrieb (Swing drive) page 31. Thirty-one exploded diagrams covering the entire machine. Each diagram has its own index of part numbers, quantities, and descriptions. If you are rebuilding a Fahrantrieb mit Parkbremse (drive with parking brake, page 26), you see every gear, bearing, and seal listed. No missing items.

Is This Catalog for the Whole Machine?

Yes. The HR 26 crawler excavator – all major assemblies. The catalog includes the undercarriage, dozer blade, upper carriage, oil and diesel tanks, operator cab, king post, boom, dipper arm, bucket rod, tilt lever, adjustable dozer blade, valve operation (both ISO and Schaeff standard), swing brake control, clam-side leveling bucket controls, heater, engine shut-off, pump drive, hydraulic circuits for circulation, drive, swivel, backhoe, and the optional dozer blade with pump. That is 31 discrete assemblies, each with its own parts list.

3 Sections You’ll Use Most Often

Number one: the hydraulic installation chapters (pages 22–29). HR 26 machines have complex plumbing – circulation, drive, swivel, buckle, backhoe, and clam. One wrong O-ring can dump a week of work. Second: the undercarriage (page 2) and idler travel (page 3). Tracks are the most abused part. Third: the swing drive (page 31). If the excavator won’t rotate, you need that exploded view to order bearings and seals. These three sections alone pay for the catalog when you avoid one misordered part.

Why OEM Beats Aftermarket for Part Numbers

Aftermarket parts catalogs often combine multiple machine series into one drawing, leaving out critical variations. The HR 26 series D has specific part numbers for the king post (Schwenksäule, page 9) and the boom (Ausleger, page 10) that changed from earlier series. This 1983 factory catalog was printed for serial numbers starting at 033/1250. Every part listed is valid for that range. Using aftermarket sources, you might order a boom cylinder that fits a C-series but not the D. That is a week of downtime and a restocking fee. Stick with the OEM source.

Tools and Accessories: Page 1 Shows What You Need

The first diagram in the catalog (Werkzeug und Zubehör) lists the factory-recommended tool kit for the HR 26. If you are a shop owner setting up a bay for these excavators, that page tells you which wrenches, pullers, and gauges to stock. Many home garage guys skip this and end up using crescent wrenches on hydraulic fittings – that rounds off hexes and creates leaks. The tool list saves you from buying specialty tools blind.

Who Needs This Catalog?

DIY mechanics and small fleet owners who do their own parts ordering. If you own a Schaeff HR 26, you cannot trust a parts clerk to look up the correct number without this book. Owners of older construction equipment know that aftermarket catalogs often drop supersessions or use generic numbers that don’t cross. This 244-page document is the only reliable parts source for your serial range. Professionals rebuilding these machines for resale also need it – one complete parts identification saves hours of disassembly just to read a bearing number off a race.

Frequently Asked Questions

Does this catalog include torque specs or service procedures?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views, not tightening values.

Can I use this catalog to order parts for a HR 26 with serial number outside 033/1250–033/1564?

The catalog is valid for the serial range printed on the cover: 033/1250 to 033/1564. Machines built before or after that range may have different part numbers. Schaeff-Terex updated components over the production run. If your serial number falls outside, you need a later edition or a supplement. However, many undercarriage and hydraulic parts carried over across narrow serial breaks. Cross-referencing with your machine’s actual parts (remove and inspect) is always smart. Without the catalog, you are guessing; with it, you have a solid baseline. Always verify critical parts like seals and bearings against what you remove.
