Terex Schaeff SKL 820 1981 Parts Catalog

If you are trying to keep a Terex Schaeff SKL 820 running in a shop or out on a job site, you already know the headache of guessing part numbers. I have been turning wrenches for 28 years and I have seen more than a few jobs go sideways because someone ordered a lift arm pin that was 2mm off. That is why this Terex Schaeff SKL 820 1981 Parts Catalog sits on my bench. 178 pages of factory diagrams and part numbers. Original OEM print, not some scanned copy that has been resold three times. You need the exact ten-digit part number? Page 3 tells you how to read the serial number range. You need to see how the lift frame connects to the tipp lever? Page 1 has the Bildtafel. This is the stuff that keeps a loader productive and a mechanic out of trouble.

Hubrahmen-Kipphebel-Lenker: Lift Frame Diagram on Page 1

The catalog opens with the lift frame, tipp lever, guidance, and shovel protection group — that is the Bildtafel on page 1. This section covers the mechanical linkage that makes the loader bucket work. Each part is numbered, and the corresponding ten-digit part number (e.g. 5 689 638 310) appears right next to it. You do not have to cross-reference with an aftermarket website that guesses the part. The diagram is drawn in the factory orientation, so you can see how the pins, bushings, and hydraulic cylinder brackets line up. If you have ever had a loader where the bucket tips sideways because the wrong lever was installed, you understand why this diagram matters.

3 Things You Must Check Before Ordering Parts

Grab the serial number off the type shield. The shield is on the right side of the front frame near the lift frame mount (see the sketch on page 3 of the catalog). Three checks every time:

• Serial number range: This catalog covers FZ-ID.NR. 252/0231 through 252/0869. If your machine is outside that, you need the later edition: TEREX SCHAEFF SKL 820 Parts Catalog 1.85.
• Part number format: All part numbers in this book are ten digits. Example from the OCR: 5 689 638 310. Write it exactly as it appears. One digit off and the dealer sends you a gasket that does not fit.
• Original Schaeff parts only: The manual states it plainly on page 3: use only ORIGINAL-SCHAEFF-Ersatzteile. Aftermarket copies lose the factory warranty and often have dimensional tolerances that cause leaks or binding. Do not risk it on a loader that has to move dirt every day.

I have had apprentices skip this step and then spend an hour on the phone with the parts counter. The serial number is king. Write it down before you open the catalog.

Why OEM Parts Catalog Beats Aftermarket Lists

I will say it flat: aftermarket parts catalogs for construction equipment are a gamble. They often reprint old data with missing updates. This catalog is printed by Schaeff-Terex GmbH & Co KG in 1981. The parts listing for the SKL 820 was originally issued in German, English, and French — all three languages are in this PDF. The nomenclature matches what the factory engineers called each component. When you order a “Ladeschaufel-Schutz” (shovel protection), you get the exact bracket that bolts to the bucket. If you try to pull a part number from a generic website, you end up with a universal guard that requires drilling new holes. That costs you two hours of modification time. This factory catalog eliminates that. Automotive Industry Overview can tell you about loader evolution, but for specific part numbers, you need the original document.

Does This Catalog Cover Your Machine?

It covers the Terex Schaeff SKL 820 wheel loader produced from serial number 252/0231 to 252/0869. That is roughly the first production run after the model launch in early 1981. If your machine has a serial number starting with 252/0870 or higher, you need the later catalog: Schaeff-Terex SKL 863 2003 Parts Catalog is for a different model, but the SCHAEFF-TEREX SKL 853 2003 Parts Catalog might share some components. Check the serial number first. This catalog also includes the hydraulic system components, the axle and transmission groups, and the electrical parts. The table of contents lists “Hubrahmen-Kipphebel-Lenker, Ladeschaufel-Schutz” as section 1, and the rest of the 178 pages cover the entire machine in the same Bildtafel format.

One more thing: this is a parts catalog, not a service manual. It tells you what part number goes where and how to order it. It does not include torque specs or repair procedures. For those, you need a separate service repair manual. But for rebuilding a worn loader or stocking the right spare parts, this catalog is the foundation. Automotive Industry Overview may give general context, but the factory diagram is what saves you from ordering two left-handed pins.

Get the Right Part Number the First Time

Ordering error is the single biggest money waster in a shop. This catalog puts the full ten-digit number right beside the illustration. You do not have to guess. Page 3 spells it out: provide Geräte-Typ (SKL 820), Geräte-Nummer (serial), Teilebezeichnung (exact description from the catalog), Ersatzteil-Nummer (ten-digit), Stückzahl (quantity), and shipping address. If you follow that, the part arrives and bolts on. I tell every tech who touches an older loader: put a tab on page 3 of this catalog. That page has the ordering checklist in three languages. Use it.

Frequently Asked Questions

What is the difference between this parts catalog and a service manual?

A parts catalog lists every component with a part number and diagram. A service manual tells you how to remove and install it. This is the catalog only.

How do I find the correct part number for the lift frame tipp lever?

Go to page 1. Find the tipp lever on the Bildtafel diagram. The part number is listed in the table next to it. Copy the full ten-digit number, including spaces. That number goes into your order. If the diagram does not match your serial number range, you have the wrong catalog.

Can I use aftermarket parts instead of original Schaeff?

You can, but the manual specifically warns you on page 3 that using non-original parts voids the factory warranty and may cause fitment issues. For a loader that sees daily use, stick with original Schaeff parts. The cost difference is small compared to the downtime of a failed component.

Does this catalog cover the hydraulic cylinder rebuild kits?

Yes. The hydraulic cylinders are shown in the relevant sections with o-ring and seal part numbers. You need to match the cylinder serial number to the diagram. The catalog covers all cylinder groups for the SKL 820.
