Clark-hurth 275ⅢIA 1981 Parts Catalog – Factory Specs for the Michigan Wheel Loader

I have seen more aftermarket parts catalogs than I care to remember. The kind where the part numbers don’t match, the illustrations look like they were faxed twice, and you end up ordering a brake shoe that fits nothing. That is why when you need a Clark-hurth 275ⅢIA 1981 Parts Catalog, you get the OEM print – not some scanned rehash. This is the same document the Clark Equipment Company put out in 1981 for the Michigan 275IIIA wheel loader. 173 pages of part breakdowns by serial number. No guesswork.

Parts Group Coverage – From Accelerator to Wheel

Every section in this catalog is organized by the machine’s actual assemblies. The table of contents starts with the Accelerator Pedal and Linkage (page 1A5) and runs through the Axle Groups (front and rear), the Brake Group (front and rear brake assemblies, parking brake, foot controls, lines), the Cylinder Group, the Hydraulic Group, the Transmission Group, and the Valve Group. Need to find the part number for the parking brake lever linkage? That is in the Brake Group under “Parking Brake Lever and Linkage” page 1D7. The catalog shows exploded views with item numbers and part descriptions. No interpretation needed.

Why a Parts Catalog Is Not a Service Manual

Some guys buy this thinking it will tell them how to rebuild a transmission. It won’t. That is a service manual job. This is a parts catalog – pure identification. You get the part number, the quantity, and often the model serial number range that part fits. For example, the engine control section (page 1A5) lists anchor spring part numbers specific to Cummins 4046 series and Detroit 4136A. If you have the wrong anchor spring, the engine control linkage won’t return. This catalog prevents that.

173 Pages – What You Actually Get

The book is 173 pages of factory-original part breakdowns. Every page is a direct scan of the Clark Equipment print. The index on page 2 lists 20 major groups. The hydraulic group alone covers main lines, steering lines, transmission lines, and the reservoir. The wiring group includes a full wiring diagram on page 3C5, plus cab light kit, electrical equipment, heater and demister, and windshield wiper kit. You get the part numbers for the entire machine – from the boom bellcrank to the propeller shafts. Even the Tool Kits section on page 2F8 lists the special tools needed for assembly and disassembly.

Serial Number Matching – Critical

This catalog is keyed to machine serial numbers. The front page lists serial number ranges for Cummins 4046 and Detroit 4136 engines. You record your machine’s serial number inside the cover. Then you cross-reference each part listing. If your machine is serial number 1C8410DSPR822, you need the parts that match that build. This catalog gives you that. Do not use a generic aftermarket parts list – they ignore serial number breaks and you will get the wrong part.

Real-World Use Case: A Parking Brake Job

I had a customer bring in a Michigan 275IIIA with a parking brake that would not hold. Without this catalog, you start guessing part numbers. With it, you go to Brake Group – Parking Brake Assembly on page 1D6. You see the lever, linkage, and cable part numbers. You order the correct parts. The job goes from three days of cross-referencing to three hours of actual wrenching. That is the value of an OEM parts catalog.

Frequently Asked Questions

Is this a service manual or a parts catalog?

Parts catalog. It lists part numbers, quantities, and serial number applications. It does not contain repair procedures or torque specs. If you need that, get the service manual.

Does this catalog cover the brake system?

Yes. The Brake Group includes front and rear brake assemblies, parking brake assembly, parking brake lever and linkage, brake foot controls, and brake lines. Pages 1D4 through 1E1.

Can I use this catalog for a different model like the 85III?

No. This is specific to the 275IIIA. Part numbers are unique to this model and serial number range. Using it for another model will give wrong parts. We offer specific catalogs for other models – see the related manuals above.

How do I verify my part number with this catalog?

Find your machine’s serial number. Then locate the assembly section (e.g., Transmission Group). Each part listing shows the part number, description, quantity, and serial number break (if any). Cross-check your serial number against the break. If your serial falls within the listed range, that part fits. If not, move to the next variant.
