Michigan 380 Parts Catalog

I’ve seen too many guys try to save a few bucks on a brake assembly, then end up with a machine that won’t stop. That’s why you need the Michigan 380 Parts Catalog on your bench. This is the factory manual – 135 pages of exploded views, genuine Clark part numbers, and assembly breakdowns. No reprints, no aftermarket junk. You get the same book a Clark dealer used to order parts.

Brake Assembly: Why You Need the Factory Part Number

Brakes are not a guess. Turn to page 85. You’ll see the front and rear brake assembly with every spring, shoe, and adjuster called out by part number. The automatic brake adjuster assembly is on page 86. If you order one wrong part, you’re down for days. This catalog eliminates that. Use the machine serial number – it’s printed inside the front cover and on the data plate. Without it, you’re rolling dice.

135 Pages of Exploded Views and Part Numbers

Every major system has its own section. The blade and cutting edge start on page 5. The “C” frame and blade assembly, the end bits, the tilt cylinder – all drawn out with callouts. The axle assemblies (front drive page 73, rear drive steer page 79) show bearings, seals, and shafts. You aren’t guessing which bushing fits. The part number is right there. That’s the difference between a 15-minute order and a week of return shipping.

Cummins vs G.M. – Two Separate Sections

This catalog covers both engine options. G.M. powered machines from serial 2RG1 and thereafter. Cummins powered from 2RC1. The index splits accelerator pedal linkage (pages 16-17), air cleaner connections (pages 20-21), and even the ammeter (pages 114-115). If you mix them up, the parts won’t fit. The manual keeps it straight. I’ve seen guys order a G.M. water pump for a Cummins – waste of time. Follow the engine column in the index.

Does This Catalog Cover the Brake Accumulator?

Yes. Page 89 lists the brake accumulator and brake lines. The accumulator is a separate assembly from the master cylinder. If your pedal goes to the floor and you don’t have accumulator pressure, you need the accumulator part number – not a master cylinder rebuild. This catalog shows both. The parking brake assembly is on page 84. Every line, every fitting, every bracket. No aftermarket substitution cross-references. Factory only.

Order Parts Correctly Using the Serial Number

Inside the first page of the manual, there’s a note: “Always furnish the distributor with the machine serial number when ordering parts.” Do that. Write your machine serial in the blank provided. Then cross-reference the index. Need the transmission clutch groups? Pages 30 through 55 cover first and third, forward, reverse, high range, low range. Each clutch group has its own page with a parts breakdown. Don’t skim – look up the specific clutch pack. One wrong fiber disk and you’ll be pulling the transmission again.

Why Factory OEM Documentation Matters

Aftermarket parts catalogs often skip the small stuff – the seals, the snap rings, the shims. This manual includes every piece Clark put into the Model 380. The reservoir breather cap, the tailpipe, the seat (page 15), even the battery cables (page 118). If you’re rebuilding a machine that’s been sitting in a field for years, you need this level of detail. For reference on why factory documentation matters across all machinery, check the Automotive Industry Overview. The same principle applies to heavy equipment – you want the original engineering data.

If you’re working on other models, consider these related factory manuals: Michigan Model 380 Tractor Dozer Parts Manual No. 1336-R1 for an earlier serial range, or the VOLVO BM 125C Wheel Loader Parts Catalog for similar-era loaders. For a larger Michigan machine, the Michigan 851 Parts Catalog – 72-Page Factory Parts Manual covers the 851 model. All factory originals, no reprints.

One more thing about the automotive industry: Automotive Industry Overview gives context on why OEM sourcing became standard. Same reason you want a factory parts catalog – traceability and fit.

Does this catalog include torque specifications for brake assembly?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque values are not included. If you need torque specs, get the separate service manual.

How do I find the correct part number for the brake accumulator?

Use the index – look under “Accumulator, Brake” on page 89. That page shows the accumulator assembly with each component labeled. Cross-reference your machine serial number (Cummins vs G.M.) to ensure you’re ordering the correct accumulator canister. The part number format is typically 5 or 6 digits preceded by a dash. Write it down exactly, including any suffix letters. If you’re unsure, call a Clark dealer with the manual open. They’ll confirm.

I’ve torqued enough bolts to know that the only shortcut that works is using the right information from the start. This manual saves you the headache of wrong parts and lost time. Access the Factory Manual and get the correct part numbers on your first order.
