FIAT Kobelco MD300LC 1988 Parts Catalog – OEM Factory Specs for Excavator

If you’re hunting for a part on a 1988 FIAT Kobelco MD300LC and you’re flipping through aftermarket websites, you’re burning billable hours. I’ve watched junior techs order the wrong hydraulic fitting three times because they didn’t have the factory exploded view. This Parts Catalog – issued July 1988 by Kobelco Construction Machinery America – is the same 239-page binder the dealer parts counter uses. Every part number, every description, every quantity is verified against the original YC-0101 series machines. No guesswork.

Section Breakdown: What the 239 Pages Cover

The manual is split into nine sections, starting with General Information and General Maintenance, then moving through Superstructure, Undercarriage, and Attachments. Sections 5 and 6 cover Tools and Spare Parts plus Optional Parts – critical when you need to retrofit a non-standard bucket or add a hydraulic kit. Section 7 lists the nameplate data so you can decode your machine’s serial number. The real meat for a working tech is Sections 8 and 9: Electrical and Hydraulic Components, and Engine Components. Those chapters give you the exact exploded assemblies with item numbers, part numbers, and quantities. Need the heater assembly for a cab? Page 4 shows the full heater assy breakdown with capscrews, resistors, and control cables. That level of detail saves you a return trip to the supplier.

Electrical and Hydraulic Components – Factory Part Numbers

Section 8 lists every wire harness, switch, sensor, and hydraulic line. The OCR scan of this catalog shows a wiring assembly (24100J8372F5) with all connectors, battery leads, and indicator dust covers. If you’re chasing an intermittent electrical fault on a MD300LC, you’ll find the exact part number for the harness or sensor – not a generic cross-reference. I’ve seen aftermarket catalogs list a “similar” part that doesn’t match the factory connector. This catalog eliminates that risk. Pair it with the factory service manual for torque specs, but for parts ordering, this is the last word.

Engine Components – Finding the Right Piston or Gasket

Section 9 covers everything from the engine block to the intake heater and oil filter assembly. The exploded views show how each component stacks. You get the part number for the engine harness, the thermo sensing unit, even the sub tank level switch. If you’ve ever had to match a pre-1990 FIAT engine part to a modern replacement, you know how frustrating it is. This catalog gives you the OEM number so you can cross it correctly. For an overview of how internal combustion engines work, reference Internal Combustion Engine on Wikipedia – but the part numbers here are specific to the 300LC.

Audience Fit – Who Needs This 1988 Catalog?

Home garage enthusiasts who own an older excavator often get stuck because dealerships no longer stock every nut and bolt. This catalog lets you call any parts supplier with the exact FIAT Kobelco number. Professional mechanics working on a fleet will save the client money by ordering the right part on the first call. Shop owners who want to avoid liability from wrong-fit parts – this catalog is your insurance. If you work on other Kobelco models, check the FIAT Kobelco ED150, ED150-IE 2013 Parts Catalog OEM for a newer machine, or the FIAT Kobelco ED150, ED150-2 2009 Parts Catalog OEM Manual for intermediate years. The FIAT Kobelco LK650-II 1992 Parts Catalog – OEM Factory Specs covers a larger loader-backhoe. But for the MD300LC, this is the one.

Source Authenticity – OEM Press, Not Aftermarket Reprint

This is not a photocopy from a third party. The original file is a scanned OEM document from Kobelco Construction Machinery America, LLC, printed in U.S.A. in July 1988. The book number is S3YC1601-NA. Every page carries the copyright and disclaimer. Aftermarket parts catalogs often omit revision history or applicable machine serial number ranges. This catalog includes those details. The revision history on page 3 notes that Kobelco reserves the right to change specs – but the data in this edition applies to machines YC-0101 and up. You can trust that the part numbers listed were correct at the time of manufacture.

Why a 1988 Parts Catalog Still Matters Today

Older equipment doesn’t stop breaking. If you maintain a 1988 MD300LC excavator, you need the original factory part numbers to source genuine or equivalent replacements. The Electrical and Engine sections alone are worth the price. A single wrong ordering mistake can cost more than the price of this catalog. For context on the broader automotive industry and how parts catalogs fit into service workflows, see Automotive Industry Overview on Wikipedia. But for your specific machine, this is the only parts catalog you need.

FAQ

Is this the same manual the dealer uses?

Yes. It’s the exact OEM parts catalog issued by Kobelco Construction Machinery America in 1988. Dealers used this S3YC1601-NA binder to order parts for the MD300LC.

Can I use this to identify parts without the machine VIN?

The catalog applies to machines with serial number YC-0101 and up. If your machine falls in that range, the part numbers and exploded views match. For machines outside that range, you may need to verify with your dealer. The catalog includes an applicable page that lists the serial number break. For example, the heater assembly on page 4 is listed under YC-0101 – so if your machine is YC-0102, you’re good. If it’s earlier, some parts may differ. Always cross-check the section nameplate data (Section 7) to confirm your machine matches the catalog’s applicable range. This catalog has saved me hours when I couldn’t read the faded part number on a 30-year-old component – I just matched the illustration to the shape and found the number.
