Michigan 125A Parts Catalog

Michigan 125A Parts Catalog – if you are working on a 125A Tractor Shovel, you need the OEM parts breakdown. Aftermarket parts lists are garbage. I have seen guys order the wrong wheel cylinder because some third-party catalog swapped front and rear numbers. This factory manual runs 139 pages and covers every nut, bolt, seal, and bracket. It is not a repair manual – it is a parts manual, meaning you get part numbers, not torque specs. But without the right part number you are dead in the water. I keep a copy on the tablet in my roll cart.

7 Systems Covered – Not One Missed

Flip through the index. You get the Brake Assembly—Front Axle (page 63) and Brake Assembly—Rear Axle (page 64) broken out individually. The Brake Lines and Fittings run pages 69-70. That matters when you are chasing a leak on a jobsite at 6 AM and the parts counter wants the exact tubing number. The Wiring and Parts section (page 75) gives you the battery holder, cables, and ignition components. You also get Boom Cylinder Assembly (page 61) and Bucket Cylinder Assembly (page 62). Every cylinder has its own exploded view. No generic “hydraulic cylinder” nonsense.

Does the Manual Cover the Fuel System?

Yes. The index lists Fuel Lines (page 15), Fuel Tank and Mountings (page 17), and the Primary Fuel Filter (page 15). The engine itself gets a separate engine manual – that is referenced at the front of this parts catalog. You are not left guessing which filter element fits. Part numbers are original Clark Equipment numbers. Cross-check them with your local dealer and they will match.

Original OEM Print, Not a Re-digitized Mess

This is a scan of the original Clark Equipment Limited parts manual – No. 401 for the Model 125A Tractor Shovel. The OCR excerpt on page 1 shows the “IMPORTANT NOTE” about part prefixes: parts prefixed with ‘M’ are interchangeable with American parts; parts prefixed with ‘AW’ are British design and not interchangeable. That kind of detail saves you from ordering a part that does not fit. I have seen aftermarket reprints omit those prefix notes. Then the apprentice bolts an AW part onto an M machine and strips the threads. Do not be that guy.

If you need the next revision, check the Michigan 125A Series II Tractor Shovel Parts Manual No. 402 for later serial number breaks. There is also a MICHIGAN 125A TRACTOR SHOVEL PARTS MANUAL that covers the same base model. And for the older ‘1670’ manual run, see the Michigan Model 125A Tractor Shovel Parts Manual No. 1670.

Brake Systems: Detailed Explosions

The manual covers both front and rear brake assemblies, the brake pedal gear and controls, parking brake controls, the master cylinder, and the hydrovac assembly. For a machine that pushes dirt and snow, the brakes take a beating. You can order the correct wheel cylinder rebuild kit without pulling the drum twice. The Brake System Master Cylinder section on page 71 gives you the master cylinder assembly with individual pistons, seals, and springs. If you are doing a total brake overhaul, you need this book open on the bench.

Wiring Diagrams and Steering Cylinders

Page 75 covers the Wiring and Parts as well as the Battery Holder Wiring and Parts. Yes, it includes the horn, lights, and hourmeter. The Steering Cylinder Assembly is on page 46. And the Booster Pump—Steering is on pages 53-54. If you are chasing a steering drift that is not alignment, you need to identify the booster pump internals. Aftermarket catalogs often skip the booster pump breakdown. This one does not.

Who Needs This Manual?

Home garage mechanics who bought a used Michigan 125A for property work. Fleet maintenance guys who want to keep parts inventory accurate. Beginners who are learning to identify components by sight – the exploded diagrams are clear and labeled. Pros who have rebuilt five of these and still need the right seal part number. If you are ordering parts and the supplier asks “front or rear brake cylinder?”, you can answer with page 63 or 64 and never guess wrong.

FAQ

Is this a service/repair manual or just a parts catalog?

Parts catalog only. It has no torque specs or step-by-step repair instructions. You still need the factory service manual for disassembly and reassembly procedures. But for ordering parts, nothing beats this.

Does it include aftermarket part number cross-references?

No. It lists only Clark Equipment OEM part numbers. That is a strength – aftermarket cross-reference books often have errors. Use this manual to get the factory number, then cross it yourself with your supplier.

For context on how these heavy-equipment parts catalogs fit into the broader industry, see the Automotive Industry Overview on Wikipedia. You will find more about the evolution of construction machinery documentation there. Automotive Industry Overview also covers the shift from paper catalogs to digital, but do not let that fool you – the data has not changed.
