Michigan 310 Parts Catalog – Factory OEM Parts Breakdown

I’ve spent more hours than I care to count hunting down part numbers for old Clark/Michigan scrapers. Customers show up with a machine that’s been sitting behind a barn since ’82 and expect me to magically know which seal goes into that air chamber. Without the factory parts breakdown, you’re guessing – and guessing on a machine with 5000 psi hydraulic lines is how you end up with a hospital visit. This Michigan 310 Parts Catalog is the actual OEM publication, not some aftermarket re-spray. 156 pages of part numbers, diagrams, and cross-references. You get the same information the Clark dealer used when these tractors were still on production lines.

Michigan 310 Parts Catalog: 156 Pages of Factory Breakdown

Every exploded view in this catalog corresponds to the original Clark Engineering prints. The Michigan 310 Parts Catalog is sectioned by system – engine, brakes, hydraulics, transmission, steering, frame. Each section lists part numbers with quantity per assembly, and where applicable, superseded numbers. For example, the Brake Slack Adjuster (page 16) shows the original Clark part number and the later replacement. If you’ve ever ordered a brake lining kit only to find it doesn’t fit because of a revision, you’ll appreciate having this document on your tablet. It also includes the machine serial number range: 52124 thru 52199 for the Tractor Section. That matters because internal changes happened mid-run.

Page 61 covers the Air Horn Foot Valve assembly. That valve is buried under the cab and nobody bothers to clean the lines before disconnecting – leads to dirt in the valve ports. The parts diagram shows every spring, plunger, and seal. Having the right seal part number means you don’t have to cannibalize a second machine.

Brake Assembly and Air Systems: Locating Part Numbers

The brake section in this manual covers the front brake assembly, parking brake assembly, brake air chamber, slack adjuster, and brake control valve. If you’ve got a 310 that’s losing air pressure at the brakes, the problem is often a worn diaphragm inside the brake air chamber (page 17). The catalog lists the diaphragm part number and the chamber assembly. Don’t waste time with generic chambers – the bolt pattern changed between serial numbers. This manual gives you the exact fit.

Also covered: brake air lines (tractor section, page 9) and the brake control valve (page 64). The control valve is notorious for sticking if the machine sat with stale air. The exploded view shows the internal spool and springs – you can order the rebuild kit by part number instead of replacing the whole valve.

Valve Systems and Hydraulic Controls

Beyond the brake valve, this catalog includes the Apron, Bowl and Ejector Control Valve (page 85), Air Horn Foot Valve (page 61), and the steering control valve (page 72). Each valve assembly has a separate parts list. The hydraulic control valve section is particularly useful for the bowl and ejector system – the GM and Cummins NT-380 versions have different valve bodies. Page 83 covers the Cummins hydraulic system, page 81 covers the GM. Mismatch the spool kit and you’ll either get no rollback or a stuck ejector.

Who Published This Manual and Why That Matters

Clark Equipment Company, Construction Machinery Division, printed this manual. It’s part number 1519-R-1. Every part number in this catalog is traceable to Clark’s original casting and forging drawings. Aftermarket catalogs often consolidate multiple models into one generic listing, which leads to a wrong bushing that fails in 50 hours. This manual is the source document. You can compare it to the Automotive Industry Overview standards for heavy equipment parts documentation – OEM is the only way to guarantee fit.

If you need the body section (the scraper part itself), that’s a separate manual – Clark Parts Manual No. 1534. But for the tractor side – engine, transmission, brakes, steering, hydraulics – this 156-page document is all you need. The Automotive Industry Overview covers the wider context of parts standardization, but this manual is specific and exact.

Check the TOC Before You Order a Single Bolt

The index at the front of this manual lists every assembly alphabetically. Accelerator pedal linkage, air cleaner connections, battery compartment, brake components, clutch cover, converter charging pump, decals, differential, engine hourmeter, fenders, fuel tank, gauges, head lamp, hydraulic reservoir, muffler, parking brake, propeller shafts, radiator, steering cylinder, transmission case, valve assemblies – it’s all there. 156 pages of factory-accurate drawings.

I’ve had technicians tell me they “just needed a part number” and ordered from a third-party site. Then the hole didn’t line up. Then they had to disassemble everything again. This catalog is the fix for that. Use it before you spend money on the wrong part. Related manuals you might need: VOLVO BM 125C Wheel Loader Parts Catalog for Volvo loaders, Michigan 851 Parts Catalog – 72-Page Factory Parts Manual for the 851 model, and Michigan 85III 1965 Parts Catalog – Factory OEM Parts Breakdown for the 85III.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values are not listed. You need the factory service manual for assembly torques.

Can I use this to rebuild the brake system on my 310?

Yes, for parts identification. The brake section covers slack adjusters, air chambers, linings, valves, and control cables. You will need the separate service manual for removal and installation procedures.

Is this a PDF copy of the original paper manual?

Yes. It is a high-resolution scan of the factory-printed manual, fully bookmarked. No reprints or third-party modifications. You get the exact Clark Equipment publication.

Does it cover both Cummins NT-380 and GM engines?

Yes. Separate sections for each engine – see page 1 for engine and accessories, pages 2-3 for controls, and pages 19-20 for fuel tank and lines. Part numbers differ between the two.

You’ve got a machine that needs parts. You don’t have time to guess and reorder twice. This is the factory document that tells you exactly which bolt, seal, gasket, or valve goes where. When you Access the Factory Manual, you’re getting the same reference the dealers used. No second-guessing, no returns because you picked the wrong brake chamber. Get the parts right the first time.
