Schäffer Lader Parts Catalog – 52 Pages of Factory Parts Data

If you’re trying to order parts for a Schäffer Lader without the factory parts list, you’re gambling with your money. I’ve seen guys pull the wrong injector three times because the aftermarket catalog skipped the sub-model suffix. This isn’t a repair manual – it’s the OEM spare parts list direct from Schäffer, covering the Schäffer Lader with the Kubota F2503-T-B engine. 52 pages of exploded diagrams and genuine part numbers. No guesswork.

Parts Identification That Makes Sense

Page 1 gives you the engine model: KUBOTA F2503-T-B. That ‘IRMER-1-S1’ suffix matters – order a standard F2503-T-B head gasket and it won’t seal. The catalog lists each part by number against an illustration. Page 3 shows the illustrated parts list header. You match the figure, read the code, and call the dealer. No cross-referencing Chilton’s nonsense.

Engine Breakdown Coverage

The manual covers the complete Kubota diesel engine – cylinder head, block, fuel system, cooling, lubrication. Every gasket, seal, bolt, and bracket has a factory number. Need the oil pan gasket for that specific IRMER variant? It’s in the sequence. Torque values aren’t here – this is a parts list. But the part number is verified against Schäffer’s own stock system.

I’ve torqued head bolts on these Kubota engines more times than I care to count. The mistake rookies make is ordering a ‘universal’ gasket set. A factory parts catalog eliminates that. You see the exact part number, you order it, it fits. Period.

3 Reasons to Trust OEM Documentation

First, this is Schäffer’s own printing – not a scanned reprint from some online aggregator. Second, the parts list is dated November 1996 (page 4 notice), which means it matches the production run of these Lader units. Third, the code number 19099-10781 ties back to the factory build sheet. Aftermarket parts catalogs? They’ll list a generic part that ‘compatible’. That gets you a cylinder head that doesn’t align with the dowel pins. Ask me how I know.

How to Use the Illustrated Parts List

Open to page 3. You’ll see the ILLUSTRATED PARTS LIST header in three languages. Each figure number corresponds to a part in the list. When you’re pulling the engine down, lay the catalog open next to the workbench. Mark the part numbers as you remove components. Ordering? Give the dealer the part number from this list – not the description. Descriptions vary by translator. Numbers don’t.

One warning: this catalog is subject to change without notice (see page 4 notice). Check the date on your unit’s serial plate. If your engine code doesn’t match F2503-T-B-IRMER-1-S1, call Schäffer directly before ordering. A 1996 list might miss later revisions.

What This Catalog Does NOT Cover

It doesn’t give you repair procedures, torque specs, or diagnostic flows. That’s not its job. This is a parts catalog only. If you need the full service manual with assembly instructions, you’ll want the Schäffer Lader Z600-BBS-EC-1 Spare Parts List Schäffer Lader Z600-BBS-EC-1 Spare Parts List – that has the exploded views plus torque values. For the D1503-M-E3B variant, check this Schäffer Lader D1503-M-E3B Spare Parts List. And if you’re curious about other Schäffer Lader models, start here Schäffer Lader Spare Parts List.

External context: the Kubota industrial engine family is widespread in construction equipment. You can read the Automotive Industry Overview for background on how these engines are standardized. But for this specific Lader, the factory catalog is your only reliable source.

Does this parts catalog include torque specifications for the cylinder head?

No. This is a parts list, not a repair manual. You need the service manual for torque values. But the part numbers for head bolts, gaskets, and washers are all listed by figure.

My Schäffer Lader has the D1503 engine – will this catalog work?

No. This catalog is specifically for the Kubota F2503-T-B-IRMER-1-S1 variant. Using it for a different engine model will give you wrong part numbers. Order the correct catalog for your engine code. If you’re unsure, check the engine data plate.

You want parts to show up that actually bolt on? Access the Factory Manual. It’s a PDF, 52 pages, original Schäffer print. No third-party or aftermarket condensed version. You get the exact part numbers that the factory used in 1996. That kind of accuracy keeps your Lader running instead of waiting on wrong deliveries.
