Factory Parts Manual for Schäffer D 25 K and D 25 Q Loaders

If you’re rebuilding a Schäffer D 25 K or D 25 Q and ordering parts by guessing from online listings, you’re setting yourself up for returns, wrong fasteners, and a job that takes twice as long. This factory **manual**—19 pages of OEM parts catalog data—lets you see exactly what goes where, what torque to run, and what part number to order. No aftermarket interpretation, no third-party redraws.

Exploded View Diagrams: Finding the Right Part

Each system gets its own exploded view. Page 7 shows the driveline assembly—gears, bearings, seals—all numbered and linked to a parts list. The diagrams are clean, factory-original. If you’ve ever fought with a blurry aftermarket scan that misaligns part callouts, you’ll appreciate the clarity here. Safety note: always verify the fastener grade before installation; the diagram marks standard vs. high-strength bolts.

Torque Specs and Fluid Capacities

Torque values are printed alongside each critical fastener. Page 12 lists hydraulic pump mounting bolt torque and wheel lug nut torque. No guesswork. Use a calibrated torque wrench—this manual assumes you have one. Fluid capacities for the hydraulic tank, engine oil, and transmission sump are given in US quarts and gallons. For the D 25 K, the cold-start hydraulic circuit requires specific viscosity; the manual calls it out.

What This Manual Does Not Cover

This is a parts catalog, not a service manual. It won’t walk you through removing the cylinder head or timing the injection pump. What it does give you is the skeleton key to ordering the right replacement parts. Use it alongside the factory service manual. Skip that, and you’ll be holding a part that almost fits—but doesn’t.

Source Authenticity: OEM Data Only

This file came directly from Schäffer’s original documentation. The part numbers are the same ones the dealer uses. Aftermarket parts catalogs often supersede numbers incorrectly or skip revision letters. This manual prints the OEM numbers as Schäffer released them. For an overview of how compact loader drivetrains evolved, see Automotive Industry Overview. If you’re curious about engine fundamentals, Internal Combustion Engine covers the basics.

19 Pages of Factory Specs

Nineteen pages might sound thin, but each page is dense. The first eight cover the engine and cooling system with all gaskets, pistons, and injection components diagrammed. The next five cover the hydraulic system—pump, control valve, lift cylinders, and attachments. The final pages address the chassis, axles, and electrical harness routing. Every page has a revision date. No wasted space.

Frequently Asked Questions

Is this manual enough to rebuild my D 25 K engine?

No. Use it with the factory service manual for disassembly and reassembly procedures.

How do I use part numbers from this catalog to order parts?

First, locate your loader’s serial number. Then find the correct exploded view for your system (e.g., hydraulic pump on page 12). Cross-reference the part number with Schäffer’s current parts list—some numbers may have supersessions. The catalog includes the original OEM number, which your dealer can verify against their system. Always check the revision letter in the diagram against the parts list to avoid ordering the wrong iteration. This manual saves you the headache of matching vague descriptions or aftermarket cross-references that don’t fit.

Factory data beats aftermarket every time. Access the Factory Manual and keep it on your bench next to your torque wrench. You’ll save time, avoid returns, and get the job done with the right parts the first time.
