Oakes Manufacturing L-600 Parts Catalog – OEM Parts Breakdown for Your Loader

Ever order a part for your L-600 and get the wrong one because some online parts diagram was a photocopy of a photocopy? I’ve seen it happen. You lose time, money, and sometimes the machine sits. This Oakes Manufacturing L-600 Parts Catalog is the original factory document—64 pages of what you actually need to order parts correctly the first time. No guesswork.

If you’re working on an L-600 Rounder Hydrostatic Loader, you need the exact part numbers from the source. Aftermarket parts lists get things wrong—I’ve had a customer order a hydraulic cylinder seal kit based on a third-party list and it didn’t match the bore. Page 24 covers the electrical system completely: wires, switches, solenoids. Page 26 shows the engine and attaching parts with every bolt and bracket. That level of detail is what keeps the machine running.

Loader Parts Section – From Main Frame to Idler Assembly

The Loader Parts section runs pages 4-28. It covers the main frame (both old and new style), lift arm assembly, rims and tires, hydraulic circuitry with either 2-spool or 3-spool valve setups, hydrostatic pump and circuitry (old and new), steering controls, idler assembly, and electrical. Each sub-section has an exploded view with numbered callouts and a parts table listing part numbers, descriptions, and quantities. That means you can point to the exact component you need and order it blind.

Does This Catalog Cover the Engine and Electrical Systems?

Yes. The Engine Parts section spans pages 29-45 and breaks down the cylinder block group, internal engine group, gear cover and oil pump, governor and starter, ignition group (old style too), carburetor, fuel system, and starter. Every component—down to the valve in the cylinder head—is listed with its factory part number. Electrical system parts for the loader itself are on page 24. This is not a service manual; it’s a parts identification tool. You still need the service manual for torque specs and procedures. But if you need the right gasket or bolt, this catalog has it.

7 Major Systems Broken Down with Exploded Views

Seven systems are detailed: Main Frame, Hydraulic Circuitry (2 and 3 spool valve), Hydrostatic Circuitry (old and new), Steering Controls, Idler Assembly, Engine and Attaching Parts, and Attachments (Buckets, Grapple, Pallet Fork). Each system uses clear line drawings with parts indexed to a numeric table. For example, the Hydraulic Cylinders section on page 28 lists every seal, rod, and fitting. You get the quantity needed and the exact part number. The numerical index on pages 49-52 cross-references every part number to the page and illustration callout. This is the factory system, not some generic reprint.

Use the Numerical Index to Find Any Part Fast

The numerical index is a time-saver. If you have a part number from a worn-out component, look it up starting on page 49. It tells you which page and which callout number to find. No flipping through the whole book. This catalog also includes a section for attachments—buckets (page 47), grapple (page 46), pallet fork (page 48)—so if you’re adding an implement, you know the mounting hardware part numbers. For larger loaders, check the Oakes L-1000 Loader Parts Manual. For vintage equipment, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide covers old fastener specs. And if you need wear part specs for another model, see Futura FC200-FC400 Parts Catalog – OEM Wear Parts Specs.

Attachments: Buckets, Grapple, Pallet Fork – Part Numbers Listed

Attachments are a separate section starting on page 46. If you’re retrofitting a grapple or replacing bucket teeth, the manual gives the part numbers for the entire assembly. This saves you from measuring worn parts and hoping a generic piece fits. The parts catalog is the definitive source—copying from a scanned manual that was copied from a copy loses resolution. This is a direct factory PDF from Oakes Manufacturing. Understanding how OEM parts improve reliability is critical; see Automotive Industry Overview for context on quality standards. The principles of automotive manufacturing apply here; refer to Automotive Industry Overview for background.

Stop chasing parts through memory. Access the Factory Manual and keep your L-600 running with the right components.

Frequently Asked Questions

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are in the service manual.

Can I use this to identify hydraulic cylinder parts?

Yes. The Hydraulic Cylinders section on page 28 lists every seal and rod. You’ll need the part number and quantity.

What is the difference between “Old Style” and “New Style” sections?

Good question. Oakes updated the L-600 over the years. The manual separates the older production models from the newer ones. For example, the Main Frame and Attaching Parts have separate sections for Old Style (page 6) and New Style (page 4). Same for Hydrostatic Circuitry and Idler Assembly. If you’re not sure which you have, you need to compare your loader’s serial number or visually inspect the components. The manual gives exploded views for both, so you can match parts. This is critical because ordering the wrong style part will not fit.

Is this the same as the Owner’s Manual or Safety Manual?

No. This is the Parts Catalog (part number 01555012). The Owner’s Manual is 01556010 and Safety Manual is 02076017. Each serves a different purpose.
