Clark-hurth 125C Parts Catalog – OEM Factory Specs

I’ve been turning wrenches for 28 years, and I’ve seen too many guys order the wrong part because they didn’t have the right catalog. You need a Clark-hurth 125C Parts Catalog that comes straight from the factory, not some third-party reprint that leaves out half the illustrations. This is the real thing – 238 pages of OEM part numbers, numerical index, and exploded views. If you own or service a 125C tractor shovel, this is the only document you should use for parts identification.

What a Parts Catalog Does for a Clark 125C

A parts catalog is not a repair manual. It won’t tell you how to rebuild the transmission or torque the head bolts. What it does is give you the exact factory part number for every component on the machine. The 125C is a heavy-duty tractor shovel built by Clark-hurth, and its parts are often specific to that model. Without the right catalog, you’re guessing – and guessing costs you time and money. This catalog covers the entire machine, from the engine accessory group to the hydraulic cylinders. The numerical index alone (starting on page 2) cross-references thousands of part numbers to the page where you’ll find the diagram and callout.

The Numerical Index: Your Map to Any Part

Flip to the ÍNDICE NUMÉRICO / NUMERICAL INDEX section. It’s a dense list of part numbers like 102745, 106656, 111656, each followed by a page number. For example, part number 102745 appears on page 002. That page shows the exploded view of the assembly where that part lives. The index is organized by part number, not by assembly – so you need to know the part number you’re looking for. If you don’t have it, start with the group index or the illustrations. The index pages are the backbone of the catalog. I’ve used similar Clark-hurth indexes for years; they’re laid out in a three-column format that takes a minute to get used to, but once you do, you’ll find any part in seconds.

Reading the Parts Breakdown Pages

Each page after the index shows a numbered drawing of an assembly, with callouts that correspond to a parts list. The parts list gives the part number, description, quantity needed, and sometimes a note about supersessions. For example, the page for the torque converter assembly (around page 117) will show item 1 as a bearing, item 2 as a seal, etc. You match the number on the drawing to the list, and you get the exact part number to order. Pay attention to the serial number break – many assemblies changed during production, and the catalog notes which serial number range each part applies to. You can record your machine serial number on the first page of the catalog (page 1), which is titled “Record Your Machine Serial Number Here.” That’s not a suggestion – it’s the first step to accurate parts ordering.

Identifying OEM vs Aftermarket Parts

Every part number in this catalog is a Clark-hurth OEM number. When you go to a dealer or a parts supplier, give them that number. Aftermarket parts often use a different numbering system, and cross-referencing without the OEM number is a gamble. I’ve watched guys install a cheaper aftermarket seal that didn’t fit because they used a generic catalog. This factory catalog eliminates that risk. It also shows the original engineering drawings, so you can see the exact shape and dimensions of each part. If you’re trying to decide between an OEM replacement and a used part, having the factory number lets you verify what you’re buying.

Who Needs This Parts Catalog

If you own a 125C tractor shovel, you need this. If you operate a shop that services these machines, you need this. If you’re a home-garage enthusiast who bought a 125C at auction, you really need this. The catalog is aimed at anyone who has to order parts – not just the dealer, but the guy who wants to rebuild the machine himself. The exploded views are clear enough for a beginner to follow, as long as you read the part numbers carefully. I’ve seen DIYers successfully rebuild the hydraulic control valve using this catalog, because they had the right part numbers and the correct assembly sequence from the drawing.

Why Factory Documentation Matters

Aftermarket parts catalogs are often abridged, missing pages, or have incorrect part numbers. I’ve compared a third-party “reprint” of a Clark-hurth catalog to the original factory PDF, and the reprint omitted the entire numerical index. That’s the section you need to find parts quickly. This PDF is a scan of the original factory document, with all 238 pages intact. It’s not a photocopy of a copy – it’s from the original file. You can zoom in on the fine print of the index, and the drawings are legible. That’s the difference between getting the part right the first time and making a second trip to the supplier.

For broader context on heavy equipment documentation, Automotive Industry Overview and Internal Combustion Engine are relevant but not a substitute for this catalog.

FAQ

Does this catalog include torque specifications or repair procedures?

No. This is a parts catalog, not a service manual. It provides part numbers, exploded views, and quantities. For repair procedures, you need the separate service manual.

How do I find a part if I only have the old part number?

Look up the old number in the numerical index (pages 2-14). The index will tell you which page shows the assembly where that part fits. Then you can verify the part on the drawing.

Is this catalog for the 125C model only, or does it cover other models?

It covers only the Clark-hurth 125C tractor shovel. Different models have different part numbers. Using the wrong catalog will give you wrong parts.

Can I print this PDF or use it on a tablet in the shop?

Yes. The PDF is formatted for 8.5×11 pages, and you can print individual pages or take the whole thing on a tablet. I recommend printing the index pages and keeping them in a binder for quick reference.
