Michigan 125 Parts Catalog

I’ve been torquing head bolts since before some of you were born, and I’ve seen more parts catalogs than I’ve had hot meals. If you’re working on a Michigan 125 tractor shovel, you don’t want some aftermarket parts list with fuzzy drawings and parts numbers that don’t match. You need the real deal: a factory OEM Parts Catalog. This one is 110 pages, printed by Clark Equipment, and covers the Model 125 III A Articulated Tractor Shovel. It tells you exactly which part goes where, from the front axle to the cab wiring harness. None of this “looks like it should fit” nonsense.

Engine and Accessories: Page 1 Coverage

Page 1 lists the engine accessories: alternator, oil pressure lines, and the engine itself. When you need a new starter button or an engine hourmeter, this catalog gives you the Clark part number so you order the right piece the first time. I’ve seen guys waste a full day because they ordered a generic air cleaner that didn’t line up with the mounting bracket. This catalog ends that guessing.

Brake Assembly and Air Lines – Front and Rear

Pages 39, 43, 47, 56–58 cover the brake system: air brake valve, slack adjuster, air chambers, parking brake, and the foot valve. If you’re replacing a brake chamber or an air line, you check the exploded diagram, find the reference number, and order the exact part. No more “I think this is the right one.” The brake controls and parking brake assembly are also broken down, including the hand brake and de-clutch valve.

Transmission Clutch Groups and Converter

Pages 25–26 cover the clutch groups: first and second, input – reverse, third and fourth. The torque converter assembly and charging pump are on pages 32–33. The transmission control cover assembly, oil filter cartridge kit, and converter pressure regulating valve are all listed with proper part numbers. If you’re rebuilding the transmission, you’ll need this catalog to identify every seal, gasket, and bearing. Otherwise, you’ll be chasing parts from three different suppliers and still end up with the wrong clutch pack.

Hydraulic System Coverage – Bucket, Boom, Steering

The hydraulic system takes up several pages: bucket and boom hydraulic system (pages 70, 71, 71A), steering system (page 66), and the hydraulic pump for bucket/boom (page 74) and steering (page 64). Hydraulic oil reservoir, filter assembly, and suction lines are all diagrammed. When a boom cylinder starts leaking, you need the right seal kit. This catalog shows you the cylinder assembly breakdown on page 73 so you can order the exact piston seal and wiper.

Why Use a Factory Parts Catalog Instead of Aftermarket?

I’ve had aftermarket catalogs that mislabeled a front axle differential carrier as the rear drive version. Cost me two days and a customer. This OEM catalog is direct from Clark Equipment (La Brugeoise et Nivelles S.A., Belgium). It includes the machine serial number recording page, the correct part number sequences, and the assembly drawings that match what’s on your machine. For example, the front drive axle assembly (page 39) and rear drive axle (page 43) are separate, with different part numbers for the planet carrier assemblies. You can’t get that accuracy from a third-party scan. If you want to keep your Michigan 125 running without chasing ghosts, this is the document you need on your bench.

Audience Fit: Who Actually Needs This Catalog?

Home garage enthusiasts working on a retired Michigan 125, shop mechanics doing a full teardown, or equipment owners trying to keep the loader in service. If you’ve ever ordered a “compatible” brake chamber only to find the bolt pattern is 1/4 inch off, you already know the value of this catalog. It saves you the headache of returning parts and waiting for the right ones. Plus, if you’re a beginner, the exploded views show you how everything fits together so you don’t reassemble something backwards. Pair it with the Michigan Model 125 Series III Parts Manual for service procedures, and you’ve got the complete package.

What Does “110 Pages” Actually Get You?

Every page is a factory-printed diagram with reference numbers and a corresponding parts list. The index starts on page 3 and lists every component from Accelerator Pedal to Wiring Harness. You get detailed sections for cab assembly, electrical wiring diagrams (pages 84–90), steering cylinder, bucket leveler, and even decals and name plates. The PDF is a direct scan of the original manual, not a reprint with missing pages. When you download it, you can zoom in on those tiny part numbers without losing clarity. This is the same document that Clark dealers used in the 1970s.

FAQ: Four Questions You’ll Have

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. For torque values, you need the factory service manual. Check out the Michigan 125 Parts Catalog CL. 32174 – 32189 GM-DAF if you need a different model range.

Can I use this catalog to rebuild my transmission?

You can identify every part in the transmission, but you’ll also need the service manual for disassembly and reassembly procedures. The parts catalog shows you what goes where; the service manual tells you how to put it together. The Volvo BM Michigan 125C 1988 Parts Catalog – Factory OEM Parts Manual might be relevant for later models, but confirm your serial number.

Will this catalog help me order the right brake valve?

Yes. Page 58 shows the air brake valve and controls with part numbers. Compare your old valve to the diagram to verify. If the diagram matches, you order the correct part.

Why should I trust this catalog over a free online parts list?

Because free lists are often OCR copies with errors. This is a direct factory scan with no missing pages or transposed digits. One wrong digit can cost you $200 and a week of downtime. This catalog is the real OEM documentation, printed by the company that built the machine. For context, you can read about the Automotive Industry Overview or the Automotive Industry Overview – but the bottom line is: factory parts are factory parts.

Get the Right Part the First Time

Ordering parts for a Michigan 125 doesn’t have to be a crapshoot. With this catalog open on your tablet or printed out, you can cross-reference every bolt, hose, and bearing. Don’t waste time measuring old parts and hoping. Download the Factory Manual now and get your loader back to work.
