Michigan 310 III Parts Catalog

If you’ve ever tried to order a brake slack adjuster for a Michigan 310 III and ended up with the wrong air chamber, you know why this manual exists. I’ve seen guys pull parts off a shelf based on a “looks close” match and then spend half a day re-plumbing air lines that don’t line up. That’s wasted time, and worse, it leaves a machine down. This Parts Catalog is the OEM source—144 pages of exploded views and part numbers that match what came from Clark Equipment. No guesswork. No “I think that’s the right one.” You get the exact factory breakdown for the 310 III, covering serial numbers Tractor G.M. 8VG101 and after, Scraper 55V101 and after.

Brake Components: Slack Adjuster and Air Valve

The brake system on a scraper isn’t something you want to patch together. The manual lists the Brake Slack Adjuster on pages 55, 115, and 117 in both tractor and rear brake assemblies. You’ll also find the Air Brake Valve (page 57) and the Brake Air Chamber (pages 55, 115, 117). These aren’t generic part numbers—they’re Clark-Approved numbers tied to the specific brake assemblies. If you need to replace a brake shield, that’s on page 17. The exploded view shows every bolt and bracket so you don’t buy a part that won’t fit.

Pay attention to the serial number ranges. The manual explicitly states: “Always furnish the distributor with the machine serial number when ordering parts.” That’s on page 3. I’ve seen too many mechanics skip that step and end up with a brake air chamber that has the wrong mounting flange. Don’t be that guy.

Valve Assemblies: From Air Brake to Hydraulic Control

The Valve coverage in this catalog is extensive. You’ve got the Air Compressor Governor (page 59), Downstream Pressure Regulating Valve Assembly (page 42), Cockpit Hydraulic Shift Control Valve Assembly (page 35), and the Hydraulic Control Valve Assembly (page 91). Each entry comes with the Clark part number, the quantity used, and an exploded diagram showing seals, springs, and bodies. If you’re rebuilding a valve bank, you can cross-check o-ring sizes against the factory listing. Aftermarket catalogs often combine several variations into one “universal” number—that’s how you get leaks. Stick with the OEM listing.

The Brake Valve, Air (page 57) is a specific unit. Don’t substitute a truck-style valve. The manual even includes the Air Horn and Horn Valve on page 59. Yes, even the horn gets its own page. That’s the level of detail here.

144 Pages of Exploded Views and Part Numbers

This isn’t a service manual. It’s a parts catalog—144 pages of index-organized breakdowns. You get the tractor and scraper sections separately. The Axle Assembly – Tractor (page 51), the Differential and Carrier Assembly (page 56), the Torque Converter Assembly (pages 39, 41)—all with clear diagrams and callouts. Even the Bottom Tank, Radiator (page 12) and the Radiator Core (page 12) are broken out so you can order the correct coolant passages.

Want to find the Cartridge Kit, Oil Filter – Transmission? It’s listed on pages 1 and 47. The index (starting on page A) gives you page numbers for over 200 assemblies. If you’re a shop owner, keep this manual by the parts counter. Hand it to your parts guy and say “find it here, then order it.” No more returns because someone picked the wrong Brake Slack Adjuster.

Finding the Right Part: Serial Number Ranges

Every parts manual from Clark Equipment includes a serial number range. Page 1 of this catalog states: “TRACTOR: G.M. – 8VG101 and after; SCRAPER: 55V101 and after.” If your machine falls outside those numbers (unlikely, but possible), you need a different manual. That’s why we carry related editions like MICHIGAN 310 III TRACTOR SCRAPER PARTS MANUAL No. 2448 and the Michigan Model 310 III Tractor Scraper Parts Manual No. 2145. For other heavy equipment, check the VOLVO BM 125C Wheel Loader Parts Catalog.

Cross-referencing serial numbers isn’t just a suggestion—it’s the difference between a part that bolts on and one that grinds against the frame. The manual also includes a warning on page 3: “Claims for damages, during shipment, should be made to the carrier immediately.” That’s a reminder to inspect parts right away. If you order a Valve from the factory listing and it arrives wrong, you have recourse. If you ordered from a third-party catalog with a generic number, you’re stuck with the return shipping.

Does This Manual Cover the Fuel System?

Yes. The Fuel Tank and Lines, Battery Compartment and Batteries section (page 15) includes the fuel filler cap, dipstick, strainer, and lines. The Fuel Filler Cap and Battery Hold Down are both on that page. If you need the Battery Cables or Wiring and Battery assembly, that’s on page 105. Everything is keyed to the original factory diagrams. No ambiguous “fuel system” drawing—you get the actual Clark part numbers.

Q: Why do I need a parts catalog if I already have a service manual?

A: A service manual tells you how to take it apart. A parts catalog tells you what to put back in. You can’t order the right gasket for a Valve assembly from a torque spec sheet.

Q: How do I know if my tractor serial number is covered?

The catalog covers Tractor G.M. 8VG101 and after, and Scraper 55V101 and after. If your serial number falls before these, you need an earlier edition. Check the plate on the frame—usually stamped near the steering cylinder mount. If you can’t find it, contact Clark with your machine model and year. But for the vast majority of 310 III machines in the field, this is the correct manual. It also includes the Air Filter, Brake Lines – Scraper (page 119), the Ejector Cylinder Assembly (page 126), and the Decals – Scraper (page 129). That last one might seem trivial until you need a replacement warning decal for safety inspection. Every page is factory original, not a third-party redraw.

You’ve got the machine. You’ve got the serial number. Now you need the parts. Don’t waste time flipping through cheap online parts diagrams that hide the real part numbers behind affiliate links. This is the real deal: 144 pages of OEM data printed in the U.S. by Clark Equipment. For reference on why factory documentation matters in the Automotive Industry Overview, that link covers the importance of standardized parts tracking. And if you’re curious about the broader scope of Automotive Industry Overview, that’s also worth a read. But right now, you need a brake slack adjuster for your 310 III. Access the Factory Manual and get the part number from the book before you pick up the phone.
