Michigan 275-B, 425C101 Parts Catalog – Factory OEM Parts Manual for Articulated Tractor Shovel

Let me save you a headache. You’re trying to rebuild a Michigan 275-B, 425C101 Parts Catalog machine and the local parts guy keeps asking you for a part number you don’t have. Or you’ve already ordered a brake chamber that didn’t fit because the aftermarket catalog had the wrong illustration. I’ve been there – wasted hours chasing parts that don’t match. This 188-page factory manual from Clark Equipment puts every single part number for the 275-B Articulated Tractor Shovel in front of you, sorted alphabetically so you find what you need without guessing.

Brake System Parts: What the Manual Lists

Brakes on a loader are not something you want to mess up. This manual covers the entire brake system in multiple alphabetical groups. You get the Air Chamber Brake (section A3), the Brake Assembly itself (section B8), and the Parking Brake Assembly (section A5). There’s also the Brake Hand Valve (section B5), Brake Relay Valve (sections B5, B7), and the Brake Check Valve (section B7). Every part number is illustrated with exploded views so you can confirm you’re ordering the correct diaphragm, spring, or clevis. The index even includes “Brake Air Lines” at B5 and B7 – critical if you’re replacing rusted lines and need the factory routing.

Air Brake Lines and Valves: Factory Routing Diagrams

If you’ve ever tried to trace air lines on a 275-B without a diagram, you know it’s a rat’s nest. The manual shows the Air Lines Brake in sections B5 and B7, plus the Air Valve Brake in V2. You’ll also find the Air Reservoir (B5, B7) and Air Pressure Gauge (E5). These pages give you the exact part numbers for each fitting, line, and valve body. Don’t waste time measuring old lines – use the factory part number and order the correct pre-formed hose. The manual also lists the Alcohol Injector (Z3) for cold-weather operation, which is often missed by aftermarket sources.

Finding the Right Part Number

Open the manual and go straight to the alphabetical index starting on page 1. Need a new boom cylinder? Look under “Boom Cylinder Assembly” in section C10. Axle components? Sections A3 through A8 cover front and rear axle assemblies, differentials, and planet carriers. Every part number is tied to your machine’s serial number – and this manual specifically covers 275B machines with Cummins engine, serial numbers 425C101, 425C101ENC, and 425C101FSC. Write down the quantity, part number, and description before calling your distributor. That’s how you avoid “I think this is the right one” returns.

188 Pages of Factory Specs

188 pages might sound like a lot for a parts catalog, but each page is packed with exploded diagrams and callouts. The manual is organized alphabetically by component group, then each group has its own page numbering (like A1, A2, B1, B2). Revision numbers are appended with a hyphen – so if Clark updated a part, you’ll see the latest version number on the page. This is not a reprint from a third party; it’s the original OEM document published by Clark Equipment Company. The abbreviations and symbols listed at the front (e.g., “NOT ILLUSTRATED”, “NOT SOLD SEPARATELY”) help you interpret the drawings correctly.

Does This Manual Cover the 425C101 Serial Numbers?

Yes – the cover page explicitly states it contains information for machine serial numbers 425C101 and After, including 425C101ENC and 425C101FSC. If your machine falls outside that range, you’ll need a different manual. This precision is exactly what you want when ordering a $400 brake valve assembly. The manual also includes Group Z in the back for optional and accessory items, such as the Alcohol Injector or protective structures.

I’ve spent 28 years under hoods and under machines. Aftermarket parts catalogs often omit the small hardware – the lock washers, the O-rings, the special bolts – that you can’t find at a hardware store. This factory manual includes every piece. The Valve section (V2) alone covers air brake valves, control valves, and safety valves. You won’t have to guess whether a spring is included in the assembly; it’s all there in the illustration.

One more thing: always cross-check the part number with your distributor using your machine’s serial number. The manual even says “Always furnish the distributor with the machine serial number when ordering parts.” That’s not a suggestion; it’s the only way to guarantee fitment.

Automotive Industry Overview is also a good starting point for understanding equipment standards.

Is this the original factory manual?

Yes, printed by Clark Equipment Company, not a copy.

Does it include torque specs?

This is a parts catalog, so it lists part numbers and exploded views – not service procedures like torque values. You’ll need a separate service manual for that. However, each part illustration shows assembly order and quantities, which helps confirm you have all the pieces before starting the job.

How do I order parts from this manual?

Start by recording your machine’s serial number (found on a plate near the operator station). Look up the component in the alphabetical index (e.g., Brake Assembly – page B8). Find the correct illustration, read the callout numbers, and write down the quantity, part number, and description. Then call your Clark distributor or check with a dealer that handles Michigan equipment. Give them the serial number and part number – they’ll confirm availability and price. This manual also includes notes like “NOT SOLD SEPARATELY” so you know which parts come only as an assembly.

Can I use this for the 275-B with a different engine?

This manual is specific to the 275B with Cummins engine, serial numbers 425C101 and after. If your machine has a different serial prefix (like 425C100 or earlier), the part numbers may differ. Check the cover page – it lists exactly which serial number ranges are covered.
