Michigan 310 III Parts Catalog – OEM Factory Parts Manual

You’ve got a Michigan 310 III tractor scraper on the lift, and you need a brake slack adjuster. You pull the old one, see the part number is worn off, and order three different possibilities from three different suppliers. Two arrive wrong, one is close but the casting is different. That’s a day wasted, and the machine sits. I’ve been there. A factory Parts Catalog kills that guesswork. This is the original document from Clark Equipment Company – not a third-party reprint, not a scanned PDF with missing pages. You get the same part numbers, diagrams, and index that the dealer’s parts counter uses. 92 pages, bound as a manual, covering the tractor section of the 310 III for serial numbers 5VG101 through 5VG999.

92 Pages of Factory-Indexed Parts

Every page in this catalog is built around the OEM index. Flip to the index (page 3 of the manual) and you see Brake entries listed alphabetically: Brake Slack Adjuster, Brake Air Chamber, Brake Air Lines, Brake Assembly – Front, Brake Controls, Brake Shield, Brake Valve, Air. Each one points to a specific page number. You don’t flip through random sections. You go straight to page 47 for the brake slack adjuster or page 49 for the air brake valve. That index is the difference between a 5-minute part lookup and an hour of frustration. The manual also includes a machine serial number range and a supplement section for later serial prefixes like 6VG. You’ll know exactly which parts apply to your machine.

What This Catalog Covers: Brake, Valve, and Drivetrain

The catalog breaks down the Michigan 310 III into logical groups. Engine and accessories start on page 1. Transmission and torque converter assemblies run from page 17 through 40. The brake system – front brake assembly, air chamber, slack adjuster, air valve, lines – is covered from page 41 to 51. Steering system, hydraulic controls, and cab components round it out. Each assembly has a clear exploded diagram with numbered callouts. You match the callout number to the parts list, get the part number, and order it. No ambiguity. The manual also includes a section on Valve assemblies: the hydraulic control valve (pages 71-72), the air brake valve (page 49), and the check valve (page 51). If you’re rebuilding a hydraulic system or replacing a leaky air valve, the diagram shows you exactly which O-rings, springs, and bodies belong together.

How to Use This Manual for Accurate Part Ordering

Open the catalog to the index. Find the component you need – say “Brake Slack Adjuster.” The index says page 47. Turn to page 47. You see an exploded view of the brake assembly with a callout number for the slack adjuster. The parts list below gives the part number, description, and quantity per machine. Write it down. Order against that number. That’s the whole process. The manual also includes a note at the front: “Always furnish the distributor with the machine serial number when ordering parts.” Write your serial number on the cover of the manual. Do it now. That number, combined with the part number from the catalog, gets you the right part the first time. I’ve seen guys order a brake air chamber without checking the serial number and get a chamber that doesn’t match the mounting bracket. This catalog prevents that.

Why Aftermarket Parts Catalogs Fall Short

Aftermarket catalogs from third-party publishers often re-draw diagrams, drop part numbers, or combine multiple models into one generic page. You end up with a part number that almost works – but the bolt pattern is off by a quarter inch, or the piston diameter is wrong. The Michigan factory catalog was printed by Clark Equipment Company. It’s the same document their parts distributors used. When you see a part number like “2M676B2044SPR-311” (that’s the manual’s own print code), you know it’s authentic. No re-drawn diagrams, no omitted hardware. If you’re working on a 310 III, you want the factory source. For related manuals, check out MICHIGAN 310 III TRACTOR SCRAPER PARTS MANUAL No. 2448 for the body section, or Michigan Model 310 III Tractor Scraper Parts Manual for a combined edition. For other equipment, VOLVO BM 125C Wheel Loader Parts Catalog might be useful.

Real-World Application: Rebuilding the Brake Air System

Take a common job: replacing the air brake Valve on a 310 III. You pull the old valve, it’s stamped with a number that’s partly worn. You check the catalog index – “Air Brake Valve” – page 49. The diagram shows the valve assembly with a callout for the valve body, a separate callout for the diaphragm, and another for the plunger. The parts list gives part numbers for each. You order the valve body as an assembly, and you have the diaphragm and plunger numbers in case you need them. The manual also lists the air compressor governor (page 51) and the air lines (page 51). While you’re in there, you can replace the governor and check the lines. That’s a complete system overhaul from one catalog. The Brake section alone covers the front brake assembly, slack adjuster, air chamber, and all associated hardware. If you’re doing a brake job, you need this catalog open on the bench.

Does this catalog include torque specifications for the brake assembly?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque values are in the service manual. You need both for a complete repair.

Can I use this catalog for a Michigan 310 (non-III) model?

No. The 310 III has different drivetrain and brake components. The index and part numbers are specific to the III series. Ordering parts for a 310 from this catalog will likely result in incorrect parts.

How do I know which serial number range my machine falls into?

Check the machine’s serial plate, usually on the frame rail or inside the cab. This catalog covers serial numbers 5VG101 through 5VG999 for the tractor section. If your serial starts with 6VG, refer to the supplement at the rear of the manual. The supplement is included in this 92-page document.

What if I need a part that is not listed in the index?

The index is exhaustive for the tractor section. If you cannot find a part, double-check the spelling or look under a broader category. For example, “Brake Air Chamber” is listed under “B” as “Brake Air Chamber,” not “Air Chamber, Brake.” The index uses both forms in some cases. If it’s truly missing, the part may be in the body section (separate manual, see MICHIGAN 310 III TRACTOR SCRAPER PARTS MANUAL No. 2448).

This catalog is printed on paper, not a digital file that loses resolution. It’s the original factory document. If you’re servicing a Michigan 310 III and you need to order parts without calling the dealer every time, get this manual on your bench.
