Schaeff SKL 840 1985 Parts Catalog

You are tearing down a Deutz engine on an SKL 840 and the seal kit you ordered doesn’t fit. That’s because someone used a generic cross-reference instead of the real OEM part number. This Schaeff SKL 840 1985 Parts Catalog is the factory issued book – 270 pages of exploded assembly drawings and original part numbers. No aftermarket renumbering. No “equivalent” listings. Just the exact Schaeff numbers that came off the assembly line.

Page 3 lays out the full table of contents. The catalog is organized by machine section – from Vorderwagen (front undercarriage) to Motoranbau (engine attachments), and every hydraulic circuit in between. You don’t flip through a generic index; you go directly to the assembly group that matches your job. That alone cuts parts ordering time in half.

Schaeff SKL 840 1985 Parts Catalog: What’s Inside?

The catalog covers 50+ assembly groups. Key sections include Control hydraulics, Service brake operation, Steering hydraulics, Transmission hydraulics (Deutz), Gearbox (Deutz), Differential – front axle and rear axle, Wheel hub assemblies, and the entire Quick-exchange device hydraulic manifold. Each section has its own exploded view (Bildtafel) with callouts linking to the parts table. The part numbers are original Schaeff-Terex – no aftermarket re-stamping. You also get an index by Ersatzteilnummer (part number) at the back, covering all 270 pages.

Control Hydraulics: Steering Cylinder and Quick-Exchange Device

Hydraulic system failures are the most common downtime cause on wheel loaders. This catalog includes dedicated sections for Lenkzylinder (steering cylinder), Hubzylinder (lifting cylinder), Kippzylinder (tilting cylinder), and the Schwenkantrieb (swivel drive). Every seal, rod, and hydraulic fitting is shown in the exploded diagram with a factory part number. If you need a rebuild kit for the steering cylinder, you look up the diagram, note the callout number, and cross-reference it with the numerical index. That’s how you get the correct Schaeff part without returning a box of wrong seals. Automotive Industry Overview

Differential and Axle Assemblies – Front and Rear

Differentials are specific to serial number ranges. The catalog differentiates between VA (Vorderachse – front axle) and HA (Hinterachse – rear axle). You get separate exploded views for Differential – VA, Differential – HA, Radnabendeckel VA/HA (wheel hub covers), and Radlagerung vorn (front wheel bearing). The part numbers for ring and pinion sets, bearing cones, and seals are listed with their exact Schaeff identifier. Use this alongside the service manual – the part number guarantees the fit, while the service manual tells you the preload.

How to Read the Exploded View Diagrams?

Each diagram has a reference number next to each component. The corresponding parts list gives the part number, description, and quantity per assembly. For example, in the Getriebe (Deutz) section, the gearbox housing assembly shows each bearing, shaft, and seal with a callout. The part number is printed directly – no cross-referencing to another chart. This is a true OEM layout, not a compressed aftermarket copy. Automotive Industry Overview

3 Reasons to Trust OEM Schaeff Parts Catalog

First, it’s the same document Schaeff-Terex issued to dealers in 1985 – valid from serial numbers 026/1500 to 026/2216. Second, the part numbers are traceable back to the original production line. Third, the index-Ersatzteilnummer lets you verify any part number against the illustrated list. Aftermarket catalogs omit sections like “Falt” (fold-out diagrams) or “Luderlage” (grease points) – this one includes every page from the original binder.

Gearbox (Getriebe) and Transmission Hydraulics

The Deutz engine is the heart, but the gearbox and transmission hydraulics keep the loader moving. Sections cover Getriebe (Deutz), Transmissionshydraulik (Deutz), Pneumatikhydraulik, and the universal joint (Kreuzgelenk). Each gearbox component – from the clutch pack to the output shaft – has a separate diagram. The transmission hydraulics section diagrams the valve body and line routing. If you need a new gearbox gasket set, this catalog gives you the exact Schaeff part number, not a “fits most” aftermarket guess.

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. You need the factory service manual for torque values and repair procedures.

How do I find a part number for the steering cylinder?

Open the Lenkzylinder section in the catalog. The exploded view shows every component with a callout number. Match that to the parts list table – you’ll get the Schaeff part number, description, and quantity. Then use the index-Ersatzteilnummer at the back to verify the number across different language editions. The catalog covers both front and rear axle steering components, including seals and hoses. This eliminates the guesswork of ordering from generic aftermarket lists that often mismatch. I’ve seen techs order the wrong cylinder seal kit because they used a third-party cross-reference. With this OEM catalog, you get the exact Schaeff part number that matches your serial number range. That’s 270 pages of factory data – not a photocopy of a photocopy.

Stop wasting billable hours on wrong parts. Start with the factory data. Access the Factory Manual for your SKL 840 and get the exact part numbers you need.
